Toyota Tundra 2nd gen (XK50) wheel fitment
The second-generation Tundra kept the same 5x150 hub for its whole run, from the 2007 launch through the 2014 facelift to 2021. Factory 18 and 20-inch wheels sit at ET60, so owners chasing a wider stance usually fit lower-offset wheels, often with a front level and a 33 to 35-inch all-terrain tyre.

Explained in our guides
Read these before choosing wheels for the Tundra: they explain the offset, fitment and hub numbers in this guide.
- Wheel offset explained: choosing ET without guessingUnderstand positive and negative wheel offset, calculate inner clearance and outer position, and choose an ET using measurements from your own car.
- Lifted truck wheel fitment: backspacing, 33s, 35s and trimmingPlan larger truck tyres around lift-kit requirements, backspacing, steering and articulation. Compare 33 and 35 inch tyres without assuming a lift guarantees clearance.
- Hub-centric vs lug-centric wheels: choosing hub ringsLearn what hub rings do, how to specify their inner and outer diameters, and why centring, wheel seats and vibration need separate checks.

Factory 18s with 285/75 R18 on a level

- 18 × 8 inch, ET60 · 285/75 R18
A 2018 SR5 CrewMax owner on Tundras.com runs 285/75 R18 on the factory wheels with a 2.5-inch front level, reporting a slight rub on the front arch liner only at full lock in reverse.
18x9 ET20 on a 3-inch level
- Front and rear
- 18 × 9 inch, ET20 · 275/70 R18
A 2013 SR5 in ThreePiece's Tundra build roundup runs 18x9 ET20 wheels with 275/70 R18 tyres on a 3-inch front, 1-inch rear lift. The front air dam was removed and the wheels poke about three-quarters of an inch.
Width and offset guidance
Offset range
Check the exact setup
There is no confirmed range for this car yet. Compare a known wheel with your proposed size and measure both sides.
Common width limit
Measure before ordering
A maximum width has not been confirmed. Tyre shape, ride height and alignment all change the available space.
These figures belong to the setups described here. Combining the widest wheel with either end of the offset range does not guarantee a safe fit. For how ET moves the wheel in and out, read wheel offset explained; for how far the tyre can sit out, see flush, poke and tucked fitment.
Clearance notes
- All factory 18 and 20-inch wheels are ET60, so moving to ET20–ET40 aftermarket wheels pushes the tyre a long way out. That clears the upper control arm and cab mount but brings the tread closer to the air dam and arch at full lock.
- Owners on levelled trucks commonly remove the front mud flaps and trim or remove the air dam for tyres of 285/70 R18 and larger.
- Full 35x12.50 tyres can hit the front cab mount at full lock, and some owners cut and plate the mount to clear them.
- The hub bore is about 110 mm. Use hub-centric rings if the wheel bore is larger.
- We list 131 Nm (97 lb-ft), the figure usually given for the factory alloy wheels. Steel wheels may differ, so check the owner's manual.
- Check full steering lock and suspension travel with the car loaded. Match wheel load rating, tyre load and speed ratings, fastener seats and brake clearance.

Questions
What is the bolt pattern of a 2007–2021 Tundra?
5x150, with an M14x1.5 thread and a hub bore of about 110 mm, unchanged across the generation.
What is the most common tyre size on a levelled second-gen Tundra?
285/70 R18, roughly 33.7 inches tall. 285/75 R18 is the usual next step, and owners have run it on the factory wheels with a 2.5-inch level and only slight liner contact at full lock.
What offset are the factory Tundra wheels?
The 18x8 and 20x8 wheels are ET60. The 17x8 option is ET50.
Will 35-inch tyres fit with just a levelling kit?
Often not cleanly. A 35x12.50 tends to touch the front cab mount at full lock, and most builds that run 35s use wheels around ET15–ET25 plus trimming.
What wheel size does the Toyota Tundra 2nd gen (XK50) use?
Factory wheels are 18 × 8 inch, 20 × 8 inch and 17 × 8 inch, depending on trim. The stock table lists the offset for each.
What is the Toyota Tundra 2nd gen (XK50) centre bore?
110.1 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
What is the Toyota Tundra 2nd gen (XK50) wheel nut torque?
131 Nm (about 97 lb-ft) for the original nuts. Confirm in your handbook, especially with aftermarket wheels or nuts.
