Fridays FAQ #2 Tire & Wheel Fitment

Backspace, Bigger Tires, and Clearances: 

We get a lot of questions about wheel choices.  This should hopefully clear up some of the confusion people have,  especially when dealing with IFS lifts.  The backspace and rim width are the two critical items when selecting a wheel to go with an aftermarket lift.  The backspacing will determine the clearance to the steering knuckle.  This is very important, because too much backspacing will put the rim in contact with suspension components, and will vary by the rim sizeOften times the factory rim will go back on after a kit is installed, but only with a stock tire.  You can see how much a tire overhangs the rim (tire bulge), this gets a lot worse when you go up to a 35 x 12.50 tire.  The factory width tire on most of trucks is 275mm, which translates to 10.8 inches wide.  Adding a 12.50 tire would decrease the clearance by almost 1 inch, and this is enough to make that combination not work.  This is why we specify a certain width wheel (to eliminate some of the tire bulge) and a certain backspacing (to guarantee clearance to steering components).

Too little backspacing will put the wheel outside of the wheel well really far.  This is great for suspension component clearance, but really bad for fender clearances.  When the tire sticks out it is likely to rub on the bumper and backside of the front fender while the wheel is turned.  Sometimes some creative trimming will fix this problem, but most people do not like to trim excessively on brand new trucks.  The other problem with a wheel that sticks out really far is it increases tire scrub.  This can cause issues with traction control systems as well as increase the wear on factory components. 

If you are in love with a certain wheel, contact us with the specifications, check with us before you order them.  We can let you know if you will have possible interference issues.  Don’t be too upset when we say that you should think about a different rim.  We have test fit lots of different rims and our listings represent the best specifications for getting the biggest tire on your truck.

    i have 2 inches of body lift already on my 2001 F150 and i was told i could fit 38’s after installing this kit, is this true if not what is the largest tire i can fit, the widest, and what wheel size is recommended?

  2. Zone Admin Reply

    @Justin H
    Which kit are you asking about, combining our 6” suspension lift with a 2” body? The max size is really dependent on the wheels and tires you select, the width and the wheel backspacing. Some 38’s measure out to be 36.5” actual height, so a flat answer to will 38’s fit gets a little tricky… A wider tire or smaller backspacing (stuck out farther) will be more likely to rub when turning. If you plan to run the stock fenders and stock bumpers I’d say a 37×13.50 is probably a safer bet to run with your setup. We haven’t tested combining the suspension/body lifts with that tire so we can’t guarantee their won’t be some trimming necessary, but I’d look for a 9-10” wide rim with 4.5-4.75” backspacing. Wheel diameter is up to you, the larger you go the more expensive the wheels/tires get.

    I am thinking about installing either your 4″ or 6″ suspension lift on my 2004 F150 4×4. I am currently running stock wheels (17″) with 285/70/17 Nitto Terra Grapplers. Would I run into any issues by staying with my current wheel/tire setup? Or would I need to buy an aftermarket wheel with different backspacing?

    • Zone Admin Reply

      Hey Nick, the stock 17s will not fit back on the truck after installing the lift do to clearance issues of the tie rod mounted to the new steering knuckles. We have more information on our website about recommended wheel/tire specs and feel free to call our tech support line for further clarification (888) 998-9663

    Hey there,

    I am considering your 6″ Suspension lift for my 2011 F-150 4×4. It has the 20″ wheel option, which I believe is 20 x 9.5″.

    Would I be able to continue to run the stock wheel and tire combination on this truck, and if so, what size wheel is ideal in either 18 x 9″ or 20 x 9.5″
    (offset / backspacing).

    I like the appearance of the wide lipped wheels but I realize these have huge backspace and thus, are generally not suitable in my application.

    I’m content with something like the PRO-Comp Diesel, but don’t know if any of their stock sizes are suitable for this kit.

    Thanks

    I have a 98 f150 got the zone 6″ lift and also a leveling kit for the front. I want to do 20×12 -44 offset wheel is that possible? What size tires will I be able to fit nicely? Any ideas..

    • Zone Offroad Products Reply

      Being that it’s outside our recommended wheel/tire specs, we can’t guarantee fitment without some modifications being needed. You’ll likely want to stick to a 33-35” tall tire on there to allow fitment when turning lock-to-lock. An aftermarket front bumper or front bumper trimming will open up extra clearance as well.

  6. Jeff Reply

    My current tired are 38 13.50 18 toyos and I am thinking of going down to 35 but the width of the tires I like are 12.50 will that still fit on the rims?

    • Carter @ Zone Offroad Reply

      That would depend on the width of the wheels you are currently running. Most tire companies have a recommended wheel width listing on their sites, depending on the tires its likely around an 8.5-11” wide wheel

  7. Austin Reply

    Hi, I have a 2008 silverado and am planning on doing the 4.5″ lift with 20×9 Fuel Vapor wheels with +1 offset. Ill be running 33×12.5 R20s on it. I was curious as to whether I would have any issue or if I should be ok. The offroad shop said it should all work fine.

    • Carter @ Zone Offroad Reply

      Hey Austin,
      That setup work work great and is right within our recommended specs. The 20×9 (+1 offset) measure out to roughly 5″ backspacing.

  8. Scott Reply

    I have a 2014 Silverado 1500 planning on doing a 6.5 zone lift with cali off road twisted rims 0 offset 35×12.50×20. Do I need any back spacing?

    • Carter @ Zone Offroad Reply

      Hey Scott, we spec our 6.5″ lift kit to fit 35×12.50×20 tires on 20×9 wheels with 5-5.75″ backspacing. Based on your message you seem to be a little confused on what backspacing is. Backspacing and offset are 2 ways to measure the wheel spec. Backspacing is a measurement from the wheel mounting surface to the backside of the wheel, measured in inches. Offset is the measurement of how far the wheel mounting surface is “offset” from the center of the wheel, measured in millimeter and relative to the width of the wheel. Without knowing how wide your 20″ Cali Offroad wheels are its difficult to say how 0 offset is.

  9. Chris Dunn Reply

    I have a 2009 Silverado Z71 Extended Cab. I’m going to order the 6.5″ lift. I want to stick with my factory 18″ wheels. I’m pretty sure they have back spacing of 5.7″ +31 offset. I currently have 285/65R18 Trail Grapplers but I’m worried they will look tiny after lift. I’m not wanting much outside fenders . Would like flush or less than a inch outside but would like a tire as tall as I can get. What size would you recommend and would the 285/65 look retarded if I kept them for time being. Also will I need spacers in the rear to even track width….? Tire sizes I was thing was 285/75 , 295/70 , 305/70 or if it would work a 315/70R18. If I need to trim a little plastic im good with that…I’m also not worried if I have a little rub on full lock turning. This is my weekend truck as I have a company truck as my daily driver. Thanks

    • Carter @ Zone Offroad Reply

      Hey Chris,
      your 285/65r18 tires measure out to 32.5×11.50 when they were new. You’ll still have a fair amount of clearance in the fender opening running our 6.5″ lift. We recommend the 6.5″ kit to be used with aftermarket 18×9 wheels (w/ 5″ BSing) to increase the clearance between the steering knuckle and sidewall of the tire. If you want to run the stock wheels I’d recommend contacting our tech support department for their recommendations for tire size/clearance at (888) 998-9663 or tech-zone@sporttruckusainc.com

    I have a 2500hd duramax, Im looking to do the 5in lift but want to keep my stock 18 inch wheels. Will I be able to if i put spacers and do a little trimming?

    • Carter @ Zone Offroad Reply

      Hey Ken, while aftermarket 18s are recommended, the stock 18″ wheels can be used in combination with wheel spacers to achieve our recommended 4.5-5″ wheel backspacing. For more on the topic contact Zone sales/tech support at (888) 998-9663 or sale-zone@sporttruckusainc.com

    I have a 2011 ford f150 4×4 with a 2.5 leveling kit. The wheels I want are 20×10 with -19 offset and 4.75 backspacing. Could I fit a 35×13.50r20 on my truck.

    • Carter @ Zone Offroad Reply

      That wheel/tire combo will require some fender trimming to fit with just 2.5″ of lift. Ideally you would have 6″ of lift to fit that tire/wheel combo on the ’09-14 Ford F150 trucks.

  12. Jimmy Reply

    I have the zone 8 inch lift from stage three motor sports. I’m wanting to put a 20×12 wheel. And a 37 x 13.5 nitto mud. Will that work? My truck is a 2012 f 150.

    • Carter @ Zone Offroad Reply

      Hey Jimmy, that setup is outside of our recommend specs for the F150 being that our kit is designed as a 6″ IFS lift system so we can’t guarantee fitment without any trimming being needed.37×13.50 tires on 20×12 wheels should fit comfortably on there with 8″ of lift for daily driving, however some trimming may be needed especially if used offroad.

  13. JOSH Nelson Reply

    I got your uca 3″ adventure series lift for a 07 gmc sierra 2500hd classic id like to put the 20×10 fuel vapor wheel with -18 offset with a 4.75 backspacing with 33×12.50r20 or 35s (if possible) would that work? If not would wheel spacers help?

    • Carter @ Zone Offroad Reply

      Hey Josh,
      Our recommended specs for that 3″ UCA lift kit are to fit 33×12.50 tires on 9″ wide wheels with 5″ backspacing. That said a 20×10 wheel with 4.75″ BSing can be installed, however are more likely to require some trimming to clear at full turn, especially in offroad situations where the suspension may be flexed. Wheel spacers wouldn’t help with clearance, they would actually make it tire clearance worse when the wheels are turned.

  14. Heath Reply

    I have a 2014 Ram 1500 with stock 20” wheels. My plan is to install a MaxTrack 4.5 inch lift, (4.5 inch front, 1.5 inch rear) then go with 35x 12.5 20s (BFG All Terrain KO2) and stay with the STOCK wheels. If I use 1.5 inch wheel spacers, will this combination work without any trimming or rubbing? Thanks in advance

    • Carter @ Zone Offroad Reply

      Hey Heath, being a suspension manufacturer ourselves its difficult to offer recommendations on another company’s kit without knowing their kit specifics, track width changes and wheel/tire recommendations. The Zone Offroad 4″ kit doesn’t increase track width and allows fitment of 35×12.50 tires when used with 20×9 wheels using a 4.5-5″ backspacing. Most of the factory 20″ RAM wheels are 20×8 w/ 5.25-5.5″ BSing so you’ll want to use around 1-1.5″ wheel spacer.

  15. Paul Sangineto Reply

    Hi peops, Im lookin to get your 5.5 lift kit for my 15 GMC Canyone SLE All Terrain 4×4, your recommended max tire size is 295/70 r17, my wheel is Moto metal 984 17×9, -12 offset, 4.53 bs, your listed wheel is 17×8 with 4.5 bs. Will my wider wheel be cool here, if I have to trim a little plastic inside the wheel well, my installer is cool with minimal trimming. MANY THANX…

  16. Paul Sangineto Reply

    I forgot to mention, if that set up doesnt work, would it help to drop down to a 295/65/17 or285/65/17 which is my linit, I’m even open to a 285/65/18×9 Raceline wheel, let me know my options . I aprecise your expertise, I just wanna get this right the first time…Later ,THX…

  17. Charles Reply

    I have a 2014 GMC Sierra 1500 with 18inch factory wheels. I want to get the 4.5inch lift but want to keep the factory wheels. Online it says cannot reuse 17 or 18″ wheels. Is that true and if so can I reuse with a spacer on front wheels and if so what size spacer

    • Carter @ Zone Offroad Reply

      Hey Charles, thanks for reaching out and for your interest in Zone Offroad. To answer your question the stock 17-17″ wheels can’t be reinstalled with our 4.5″ kit due to the large backspacing causing clearance issues with the new suspension components. If wheel spacers were installed to achieve our recommended backspacing measurements then you would be fine to reinstall the factory wheels. The size of spacer would depend on your particular wheel, but likely around a 1″ spacer for the front.

    Can I run 33×12.50 tires with 18×9 + 18 offset wheels back spacing is 5.708″ with your 4″ suspension lift on a 2011 silverado z71 4wd?

    • Carter @ Zone Offroad Reply

      Hey Matt,
      We spec our 4.5″ IFS Lift Kits for your 2011 Chevy Silverado 1500 to allow fitment of 33×12.50 tires on 18×9 wheels with 5″ BS. 18×9 wheels with 5.7″ BS will have a clearance issue between the wheel and steering tie rod end.

    I have an 04 Silverado 1500. I’m looking to buy the 6″ suspension lift and 3″ body lift. Im wanting to know if 315/75/16 tires with tread width 9 3/4″ and tires 16×10 with 4.5 backspace will fit if trimming isn’t an issue.

    • Carter @ Zone Offroad Reply

      Hey Katy,
      You shouldn’t have any issue fitting that tire/wheel combo on there with that amount of lift. We spec our 6″ lifts to fit 35×12.50s (equiv to 315/75r16) on 16×8 wheels with 4.5″ BS, the extra width of the 16×10 will require some trimming for clearance in all driving situations on road and off, but if you’re adding the body lift you will have the clearance. What I’d suggest is install the suspension lift, wheels and tires first to check clearance and get a better idea how much trimming would be involved. You may decide to trim rather than add the body lift.

    I have a 2017 Sierra 1500 and can’t decide between the 4.5” Lift and the 6.5” Lift. I want to fit 35×12.50×20 Toyo M/t’s. I’m lookin at the fuel Assualt rims either the 20×10 with a -18mm offset or the 20×9 with a +1mm offset. Which would be the best rout to go for the best ride. I also deliver in this truck and was looking to keep it as low as possible but will be willing to go to the 6” Lift. Just weighing my options.

    • Carter @ Zone Offroad Reply

      Hey Tyler,
      Thanks for reaching out and your interest in Zone Offroad. On your ’17 GMC 1500 you can fit a 35×12.50 tire with as little as our 4.5″ of lift, however you will need to stick to the recommended wheel specs listed on our website, 20×9 wheels with 5.75″ backspacing and even then some trimming will likely be required. Our 6.5″ lift kit is better suited to fitting that wheel/tire combo, but even then a 35×12.50 tire on a 20×10 wheel with 4.75″ backspacing may require some trimming to clear in all driving situations on and off-road.

    So I am looking into either getting your 4.5” or 6.5” suspension radius arm lift kit for my 2014 ram 2500 (Diesel) but I had a couple questions. I noticed that the 6.5” comes with a progressive coil for the rear as well as a new coil for the front, while the 4.5” kit just comes with spacers in the rear, my question is which is better for ride quality if these effect it at all? Does the coil spring in the rear make the truck ride nicer than putting a spacer in with stock spring? Also I see that you guys are saying in the descriptions that with the 4.5” lift I could clear 37×12.50 tires with a 17×9 wheel with a negative 5.625 offset. And with the 6.5” lift I could clear 37×13.50 tires with a 17×9 wheel with a negative 5.625 offset. My question about this is that I have an 18” stock wheel on right now and I can’t go down to a 17” do to clearance around the brakes so will this change anything being that I have to use at least an 18” wheel? Also will that backspacing that your calling out for make my tire stick way outside the fenders? I would like to use the 4.5” kit but was just wondering about those few things. The only reason I’m thinking 4.5 over the 6.5 is simply because I like the looks of the trucks that don’t have a bunch of fender space and I want to run 37’s no bigger. I like when the tire is closer to the fender but without rubbing on anything and without having to trim anything obviously and I like the tire to stick out of the fender a little bit but not like half of the tire sticking out. so I was just wondering if the 4.5 would work for what I’m looking to do.

    • Tyler Reply

      I would like to be able to run either 37×13.50×18 tire and wheel combo or 37×12.50×18 combo without a bunch of my tire sticking way outside of my fender but like I said I don’t mind if it sticks out a little. Basically just wondering your opinion on what my best bet would be to clear these tires and wheels.

      • Tyler Reply

        Also one last question sorry, this will all bolt right up to my truck right? Like I said 2014 ram 2500 diesel, it’s the big horn model with rear coil springs

    • Carter @ Zone Offroad Reply

      Hey Tyler, thanks for your interest in Zone Offroad. You had a lot of questions in there and I’ll try to answer them all. I’ll also say our sales team is available to assist you over the phone at (888) 998-9663 and you can stop by your local Zone Offroad dealer with questions too, http://zoneoffroad.com/find-dealer.

      Coil springs – you are correct that the 4.5″ kits are set up with front full length progressive rate coils along with a 2.5″ rear coil spacer where the 6.5″ kit uses front and rear full length progressive rate coil springs. The progressive rate coils mimic the factory front/rear coil spring design to offer a soft ride on road with the benefits of increased spring rate when towing, hauling, and cycling the suspension offroad. The factory suspension uses progressive rate coils as well, ride quality is similar with either kit, we only offer replacement rear coils for the taller lift heights.

      Wheel/tires – Our recommended wheel/tire specs are just that, recommendations based on what we’ve tested and confirmed compatible. Other sizes can be used, but may require additional modification/ fender trimming. In your case I can’t say as to whether a 17″ would be able to fit or not, I would assume it would as I don’t know of an OE big brake for the RAM that requires 18″+ wheels. Our tire tire size recommendation is listed based on 17s, but comparably specs 18-20-22-24″ wheels can be installed for similar clearance.

      Backspacing – Our backspacing measurements are on the moderate side and while they will stick out more than the factory wheels, the measurement is set up to position the wheel/tire combo for maximum clearance to the suspension and fender when driving/turning. 37s are a tight fit on 4.5″ of lift, even with following our wheel/tire recommendations. While the fit nicely for around town driving, you may find they still some minor rubbing at times when the truck is flexed out with the tires turned (offroad) that would require some additional trimming to maximize the wheelwell clearance for larger tires. The 6.5″ lift is the safer bet for tire clearance, especially if you are planning to run a wider 37×13.50 tire.

      Installation – this is a 100% bolt on kit, no welding required. Step-by-step instructions are available at

    2015 ram 1500 4×4 crew cab with 5.7l. With your zone 6 inch with 5 inch rear coil spring will a 37/13.5r22 on a 22×9.5 wheel with 5.72 in back spacing and 12 mm offset? Will I need spacers and how far will I sticknout past the fender? Thanks!

    • Carter @ Zone Offroad Reply

      Hey Brian, we haven’t tested that particular wheel/tire combo on the RAM 1500 with our 6″/5″ lift kit to give a definitive answer. That said our recommendations for that kit are for 20×9/22×9 wheels with 5″ backspacing when using 37×13.50 tires and even then some trimming may be necessary to clear in all driving situations (on and off-road). The 5.72″ backspacing will cause them the tires to be very tight to the suspension/steering and potentially rub if your tire has an aggressive sidewall, there is a chance you won’t have any issues though. In speaking with our tech support team they mentioned if using a wheel with larger than 5″ backspacing to limit tire size to a a 35×12.50 or 37×12.50 to help with potential clearance issues. We don’t take measurement of how far the tire/wheel sticks out past the fenders, best place to check out photos and judge for yourself is our customer gallery at http://zoneoffroad.com/bad-to-the-bone

    Hey guys! I just finished installing the C4 lift on my truck. It looks awesome! I have three concerns. I have a 2006 GMC 2500 lbz duramax. I have Moto Metal MO975 wheels. 17×9 wheel with 18mm offset and 5.71 backspacing, I’m running 315/70/17 currently. First concern, how much knuckle clearance is needed between the knuckle and tire. Second concern is will a 35×12.50×17 work? Right now I seem to have 2-4 mm of knuckle clearance. Its not rubbing anywhere so I didn’t know if this was ok. Third concern is my driveshaft. This is a short bed crew cab single piece driveshaft and the yoke is sticking out 2in out from where it was in the back of the transfer case. Any ideas why and if that’s ok? Looks like I only have 2 in of yoke left inside the transfer case.
    Thanks
    Nick

    • Carter @ Zone Offroad Reply

      Hey Nick, to answer your questions:

      1) if you check our website or instruction sheet we list our recommended wheel specs as 17×9 wheels (5-5.5” BS) for sufficient clearance, while you have a small amount of clearance with your current setup its ideal to have more in the event of any tire deflection to keep them from rubbing. A small 1/4” wheel spacer would do the trick to bring them back within our recommended wheel specs for 17” wheels.

      2) 315/70r17 and 35×12.50×17 are typically considered the same size tire, exact dimensions will vary slightly from tire to tire, we spec the 4.5” kits to fit 35×12.50 tires so the fact the tires aren’t rubbing is consistent with our recommendations.

      3) On your rear driveshaft, the why you asked about is because it has a lift on the truck now and that is perfectly normal. The driveshaft has a splined input into the back of the transfer case so it can move in and out as the suspension moves up and down. When you install a lift basic geometry says the distance is longer so the driveshaft length need will be longer. Our kits are designed to retain the factory driveshafts and you still have sufficient of spline engagement on the shaft. If you are concerned with it your two options are to lengthen your rear driveshaft (through your local driveline shop or swap to a longer aftermarket unit for more strength.

    I have 2007 Chevy 6″ lift and currently have 18×9 wheels with 305/70r18 tires.i have never had any problems with rubbing or suspension clearance but the tires stick out about 2 inches out of the wheel well. What wheel can I put on to bring the tires in more but keep the same height?

    • Carter Reply

      Hi Bobby, are you asking about a Chevy 1500 or a 2500/3500 model truck? The chassis/suspension are different, we offer a 6.5″ lift for the 1500 models and a 6″ lift for the 2500 models. In either case we list recommended tire wheel specs on our website, for more on the topic you can contact our customer service/tech support team at (888) 998-9663

    hello gents,
    Got a 2017 f150 FX 4 with tires 35 x 12.50, rims 17×9 , looking for a 6 inch suspensiosn lift, ur lfit says fitment 18inchs minimum, alot of people are saying that one inch wont do anything and others saying that one inch will completely screw up your build, maybe adding some Wheel spacers that i have that are 2 inch would help for when iji buy the 6 inch lift?

    Open for suggestions .

    • Carter @ Zone Offroad Reply

      Hey Matt, the reason we spec for 18″ or larger diameter wheels is due to clearance issues between the suspension/steering and the smaller diameter wheels. Our kit includes new steering knuckles that are taller and use a repositioned steering arm mount to allow the OE steering rack and linkage to be retained and function properly. Due to the new steering arm mounting location 17″ or smaller wheels (stock or aftermarket) cannot be reinstalled with our kit.

    I will be installing a zone 6.5 lift on my 2016 Silverado 1500. I want to put wheels that are 22×9 with +24 offset and with 5.94 backspacing attached to a 35×12.50R22 tire. Will this work or will i have fitment issues. Thanks.

    • Carter @ Zone Offroad Reply

      Hi Jonah, I responded to your duplicate questions on our social media pages, but to reiterate:

      Our 4.5″/6.5″ kits are designed to allow fitment of the stock 20-22″ wheels (which have a similar width/backspacing spec to the wheels you’re planning on using). The clearance between tire sidewall and steering knuckle will be tight when installing 35×12.50 tires on factory spec’d wheels and depending on the aggressiveness of the sidewall you may consider a small (1/4″) wheel spacer to bring them out within our recommended 5.5-5.75″ backspacing measurement. Other than that it will be a nice combo on there. If you have other questions feel free to ask or reach out to our sales/tech support team at (888) 998-9663

    Hi I should be receiving my 6″ lift for my 2004 chevy 2500hd 4×4 tommrow, plan on having it installed this weekend. My question is after I have the loft installed will my stock 16″ rims and 265 tires StI’ll fit until I can purchase aftermarket rims and tires? Thanks

    • Carter @ Zone Offroad Reply

      Hi Bob,
      our #C4 6″ lift kits for the ’01-10 HD allow the fitment of 16″ wheels with 4.5″ backspacing to allow for sufficient tire/wheel clearance for to with the suspension and steering. If installing them with factory 16×8 wheels (w/ 5.6″ backspacing) you’ll likely run into some clearance issues that may require a a set of wheel spacers be installed.

      Hi Kevin, officially we haven’t tested/approved our 5.5″ lift kits for the 2WD Colorado models, only 4WD at this point. That said there are a number of similarities between those models and ride height so 5.5″ of lift will allow clearance for 285/5r18 tires on a 18×9 wheel. You may run into clearance issues in the front steering that would require a set of small wheel spacers to bring them out to our recommended 4.5″ backspacing. For more on the topic contact our sales/tech support team at (888) 998-9663

    Hey on a 2018 Silverado 1500 would a 4.5″ lift work with my stock tires? they are 265 65r18.

    Ive got a ’13 ram 1500 express that has 20×9 kmc’s with a +15 offset and BSing of 5.59. If i understand it right that is too much backspace for a 4 inch lift to fit a 35×12.5 tire correct? Would that be an issue with rubbing the fender that could be fixed with a new bumper? Or with it hitting the steering/suspension components?

      Hi Jack. Our wheel tire recommendation for 4″ lift kit is to fit 35×12.50 tires on 20×9 wheels with 4.5-5″ backspacing. While stock 20″ wheels (or similar to stock spec wheels) can be reinstalled with the lift, you are limited to a factory size (width) tire due to clearance issues with the steering components. One solution would be to use a small wheel spacer to bring your current wheels out within our recommended wheel spec range.

    I have a 2006 tundra double cab with a 3 inch lift. I would like to run 295/70/17 on a set of either 17×8 with 4.5 back spacing or 17×9 with 4.75 backspace.
    Would either option work?

    • Carter @ Zone Offroad Reply

      Hi Dustin,
      Being we don’t offer any kits for the ’00-06 Tundra I don’t have accurate wheel/tire recommendations to provide. The 295/70r17 (33.5 x 11.75″) may work, but is likely a bit on the large size for 3″ of lift and may require trimming, even with 8-9″ wide wheels (4.5-4.75″ backspacing). Sorry I can’t be more help here
