Biggest Tire on A Stock 2023 Toyota Tundra (NEW GEN)
Want to know what the biggest tire you can fit on your stock 2023 New Gen Tundra running on stock suspension, then you’ve come to the right place. A big tire upgrade is usually one of the first and most popular modifications to off-road trucks since it’s the easiest way to get a more aggressive look, increase the ride height, and improve traction and capability both on and off-road. So what are your big tire options on the New Gen Tundra?
The biggest tire you can fit on a New Gen 2023 Toyota Tundra is a 33-34-inch tire without any suspension upgrades or modifications. Fitting 35s with the stock suspension without a lift kit requires some minor modifications to the wheel fender liners to be pinned back as well as removal of the mud flaps. Installing a 1.5-2” lift kit will allow your Tundra to easily handle 35-inch to 37-inch tires.
The next part of this article will discuss what is required to make a 35-inch tire fit on a stock Tundra with no lift kit. Please note that this is not necessarily the best option for your truck if you intend to do any off-roading or towing since there is minimal clearance or room for maximum wheel articulation. This is simply to answer what the biggest tire can be fitted on a stock Tundra 2023 (New Gen) without a lift kit and some minor modifications.

35-inch Options (35×12.5×20)
When doing a big tire upgrade, many Tundra owners opt for 35s. This is because the Tundra has these huge wheel arches that are just dying to be filled. Even 35s don’t do it complete justice, however, it is a much better look than stock.

Mud Flaps And Wheel Arch Carpet
The first thing you’ll need to do is remove the front mudflaps. This creates that extra bit of clearance you need to allow the wheel to turn to full lock. Every bit counts!
Next, we look at the interior lining of the wheel arches.
The nice thing about the Tundra is the veld-like carpet Toyota used instead of the usual plastic covers inside the arch. The wheel fender carpet is quite flexible and shouldn’t do any damage to the tire when turning at full lock or backing up if it touches, it’s just annoying. A simple fix is to trim away a small plastic bit behind the front part of the arch and pin the veld/carpet back.
For this job, you will need a decent heat gun and Dremel Cutting tool. If you don’t already own one then I would recommend you check out this Top-Selling Infrared Thermo gun on Amazon with almost 17000 good ratings. Also, for trimming fender liners I recommend investing in this Dremel Variable Speed Cutting Tool (Amazon) It will give you better control than an aggressive grinder leaving your trimming looking a lot more professional and neat.
You can remove the front body mount to create more clearance on the rear area of the front wheels. The carpet liner simply needs to be pulled back and re-bolted to its new position. The nice thing with the tundra is there is already a factory hole in the exact spot you want to remount the liner to so there’s no need to drill new holes to remount the carpet of the front wheel arch.
The fact that Toyota used carpet instead of plastic in the wheel arches means it’s so much easier to manipulate the wheel wells and reposition the carpets for extra clearance.
Of course, if you have a small 2” lift kit then the repositioning of the wheel arche carpets would not even be necessary.

35s on Stock TRD Pro Wheels/Rims
If you want to fit 35’s x12.5-inch tires on your stock Tundra TRD rims/wheels, it is possible, however, there will be some contact on the UCA (Upper Control Arms) which means you will need to fit a small ¼-inch spacer to create some extra clearance there. The other alternative is an aftermarket rim/wheel with a slightly less positive or more negative offset which means better backspacing.
Be aware that a more negative offset wheel/rim will mean more wheel poke which is illegal in certain countries and will require you to add some flared arches of some sort. Your 3rd option is to run a slightly narrower 35-inch tire like an 11.5-inch wide on the stock TRD rims and you should be fine.

285/75/18, thinner 35s work. If going to 35×1250 need a level up front and rim width/offset is key

35×12.5 r18 on stock suspension SR5 non off road. +18 offset Method 706’s

I had to remove the bracket that held the liner to fold and tuck the liner further back. 2 x 12mm bolts holding that bracket in each side. Only doing this temporarily until my leveling kit comes in. Then I’ll be putting them back in.

285/60r20 Recon Grapplers is what I put on my stock limited. I actually worked with the tire place and tried a few because I wanted the biggest without any rubbing. I think this is the biggest you can go for the 20-inch wheel without rubbing issues. They look amazing too!

Conclusion
In conclusion, without a 2” lift kit or suspension upgrade you are limited to 33-34” tires, and zero additional modifications are needed. If you choose to go for 35s you’ll need to do some minor modifications to the carpet in wheel wells. You will also need to remove the front mud flaps for extra clearance. A 2” leveling kit with stock TRD rims will help with UCA clearance, and If you choose to go with more negative offset aftermarket wheels, it would improve UCA clearance and backspace with no need to do any additional modifications.
