Biggest Tire on a Stock Tundra 2014-19 – No Lift
The Tundra has a very positive wheel offset from the factory so you won’t be able to fit a 0 offset or negative 12 offsets. This means the wheel hubs are pushed further outwards, which limits you somewhat to a more positive offset rim.
- Stick to +18-20 and you’ll be good.
- There might be some minor plastic trimmings, depending on how aggressive the tire tread pattern is, however, nothing is too complex, and
- No advanced tools or skills are required.
- You need to remove front mud flaps located in the front of the tire which is mounted on the front bumper and held securely by 2x 10mm bolts.
Max Tire Size with a 3” Lift Kit
The 3-inch lift kit is significantly more popular than the 4” lift kits on the Tundra’s. With a 3” lift kit you’re getting up to 1” more clearance and lift than a leveling kit and the rear is also lifted slightly.
- The maximum size you can run with a 3” lift kit on a Tundra on a 9 wide rim x20” is a 305×55.
- The positive 18 and positive 20 offset works well with this setup.
- Also, make sure you understand the implications of a lift/leveling kit if your truck is still under warranty.
- The 305mm wide x 55” tire measures 33.2 in metric values.
Max Tire Size with a 6” Lift Kit
Once you go as big as 6” leveling kits, you’re losing some of the Tundra UTE functionality and it’s becoming more of a show pony. When you go this high you can fit more than 12” wide rims with 35” tires.
- A popular choice is a negative -44 offset 12” wheel on the ’20s (20×12 -44).
- This wheel configuration offers a very wide, show-truck stance.
- If you want to squeeze in 37” tires, you’ll have to fit a front aftermarket bumper for better clearance and no scrubbing at full lock.

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.

Pinch Weld Mod
So one of the first things you’ll need to do is the pinch weld modification to get the wheels to clear properly. This is done by removing all the plastic trim and exposing the thin metal plate that protrudes.
- Many owners cut thin slits and bend the pinch weld inwards towards the wheel arch.
- You can bend it either way and then hammer the weld flat,
- If you bend it outwards you can use that thin metal strip as a flange to secure the plastic fender liner back onto.
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)
Going bigger tires might look awesome, however, you want to limit how big you go, especially if you still want to maintain the full functionality of your truck. Bigger isn’t always better since the bigger you go, the more modifications you’ll need to make as well as recalibrating your speedometer reading.
