37s on a Tundra With a Small Lift: What It Really Takes (2026)
I earn a commission if you buy through these links or codes, at no extra cost to you. I only list brands I've used or tested on my own trucks.
Yes, 37-inch tires can fit a Tundra on a small lift, around 2.5 inches up front, but the lift alone doesn't do it. Plan on cutting, and the cab mount is the big one. On a 2022 Tundra we got 37s to full lock with no rubbing after some chopping and cutting. That setup was fine for daily driving and dirt roads, but real off-road use needs more cutting.
So, we've done this on both generations. Our own 2020 Tundra ran 37s on a 2.5-inch lift, and at the shop we fit 37s to a customer's 2022. We've also put 35s on a 2025 with no lift at all, for anyone who wants bigger tires without doing too much.
What we've actually run
| Truck | Lift | Wheels and tires | What it took |
|---|---|---|---|
| 2025 Tundra (3rd gen) | None | Stock TRD wheels, 35x12.50R20 | No trimming, no mud flap removal. Barely touches the liner at full crank. Will rub if you wheel it |
| 2022 Tundra (3rd gen, customer truck) | Westcott preload collar kit | 37s | Chopping and cutting. No rubbing at full lock. More cab mount and air dam cutting needed for real off-road use |
| 2020 Tundra (2nd gen, ours) | 2.5" with ICON suspension | Method Con 6, BFG KM3 37s | The video covers the lift and wheels. See the cab mount section below |
| 2022 Tundra CrewMax (3rd gen, my brother-in-law's) | King 2.5 front, 3.0 rear bypass, Dobinsons rear coils | RRW RR7-S 17x8.5, Toyo R/T Trail 37x12.50R17 | Full overland build, and a much bigger suspension spend than a small lift kit. Total Chaos upper control arms and a chromoly rear link kit are part of it |
3rd gen Tundra (2022+): it fits, but it's a street setup at first
On that customer's 2022, the lift in the video description is the Westcott Designs preload collar kit. Runnin4Tacos lists that kit for 2022 to 2026 trucks at 2.5" front and 1" rear on static suspension, and 2" front and 7/8" rear on AVS or air ride trucks.
We made the 37s fit with some chopping and cutting, and the wheels turned to full lock with no rubbing. There was plenty of clearance for normal day-to-day driving and dirt roads. But to make that truck completely usable off-road, we'd have had to chop the cab mount some more and cut plastic off the air dam.
So that's the honest version. Full lock on pavement and full suspension travel on a trail are two different tests. If you plan to flex the truck, plan on the extra cutting.
2nd gen Tundra (2007-2021): chop or relocate the cab mount
For the 2nd gen, you have two options:
- Cab mount chop: the budget option. It removes part of the mount for clearance, but it's typically only enough for up to 34 to 35-inch tires.
- Cab mount relocate: this moves the mount further back, which makes room for true 35s or even 37s with no rubbing at full suspension travel.
If you're running true 37s and you go off-road, the relocate is the better long-term answer on this truck. The one I featured is the DRT relocate for 2007 to 2021.
Spacer or coilover for the lift?
Both can give you the same height with the same wheels and tires. They don't ride the same, though. A spacer works your factory spring and shock outside of what Toyota designed them for. A coilover replaces the whole assembly, so the shock and spring are built for that height.
The one real benefit of a spacer is that it's cheap and you keep your factory shocks a while longer. If you're fine with a stiffer ride, it works. But about 6 or 7 out of 10 customers who get a spacer lift come back wanting something different. In my spacer vs coilover video we pulled a preload collar spacer lift off a 3rd gen Tundra and put ToyTec Boss 2.5 coilovers on it, with ToyTec rear shocks and Icon rear lift springs.
On our 2020 we went with Icons. We've had Fox, Kings and now Icons, and I don't have any regrets. It rides really well all around.
Parts people forget on a lifted 3rd gen
- Upper control arms. On 4x4 3rd gens, aftermarket upper control arms are required if you lift the front more than 2 inches. ToyTec's 2.5 Boss kit is 2 to 3 inches up front and its page lists aftermarket arms as required, so budget for them. My ToyTec post has more on which kit goes with which truck.
- Axles. Longer CV axles from Toyota are also recommended. I have a separate video on the axle issue if you take a lifted 3rd gen off-road, because the stock ones can bind and fail on uneven terrain.
- Power. Our 2020 was on 37s with a lot of weight on it, and we added a Harrop supercharger to get that pep back.
Wheels
Offset changes the whole rubbing situation. The factory TRD wheel is a high positive offset, so it sits flush with the body and doesn't poke. That's a big part of why 35s clear on the stock wheels with no lift, while most of the 35s-no-lift videos out there use zero offset wheels with a lot of poke.
For 37s, my brother-in-law's truck runs RRW RR7-S in 17x8.5. When I checked, RRW listed the RR7-S in +25 for the 2022+ Tundra, and the RR7-H hybrid beadlock in +12 or +25 depending on finish. For the 2nd gen, it listed the RR7-H in 17x8.5 with a +0 offset. Check the listing for your truck before you order. The code TVO below is for Relations Race Wheels specifically.
Or just do 35s with no lift
On a 2025 Tundra we put 35x12.50R20 tires on the stock TRD wheels with no lift. We didn't even have to take out the mud flaps like we thought we would. At full crank it barely touches the liner, and on pavement and over bumps we got zero rubbing, forward and reverse. It will rub if you're actually wheeling it, so treat it as a daily driver setup. It's the cheapest way to make a 3rd gen look lifted.
My verdict
If you mostly daily drive and want the look, do 35s on your stock TRD wheels and don't touch anything. If you want 37s on a 3rd gen and you stay on pavement and dirt roads, a small lift plus some chopping and cutting gets you there, and you can turn to full lock with no rubbing. If you're going to flex it off-road, plan on more cab mount and air dam cutting on a 3rd gen, or a cab mount relocate on a 2nd gen, and budget for upper control arms and axles on the 3rd gen. For me personally, we went with Icons on our 2020 and I have no regrets. A spacer is the cheap way in and it works if you're fine with a stiffer ride, but a lot of spacer customers come back wanting something different.
On a Tacoma, see 37s on our 2024 with King shocks, or the biggest tire with no lift.
FAQ
Can you fit 37s on a Tundra with a 2.5-inch lift?
Yes. We ran 37s on our 2020 Tundra with a 2.5-inch lift, and fit them to a 2022 on a Westcott preload collar kit. Expect cutting. The 2022 needed chopping and cutting to clear at full lock.
Do you need a cab mount chop for 37s on a Tundra?
On the 2022 we fit, yes, it took chopping, and it would have needed more for real off-road use. On a 2007 to 2021 Tundra, a chop is typically only enough for up to 34 to 35-inch tires. A cab mount relocate makes room for true 37s at full travel.
What's the biggest tire on a Tundra with no lift?
We fit 35x12.50R20 tires on a 2025 Tundra with stock TRD wheels, no lift, no trimming and no mud flap removal. It's fine for daily driving, but it will rub if you wheel it.
Do I need upper control arms to lift a 2022+ Tundra?
On 4x4 3rd gen Tundras, aftermarket upper control arms are required if you're lifting the front more than 2 inches. Longer CV axles from Toyota are also recommended.
