This guide covers the six-stud four-wheel-drive GMT400 Yukon, including the two-door models and the Yukon GT appearance package, which share the same hubs as the four-door. Owners usually keep 16-inch wheels and step up to 285/75 R16 all-terrains with the torsion bars raised, while wider low-offset wheels generally need a lift and some trimming.

Read these before choosing wheels for the Yukon: they explain the offset, fitment and hub numbers in this guide.
Starting points for a build. Read the notes with each setup, especially if your car is lowered or has different brakes.
Several GMT400 forum owners run this on the factory 16-inch wheels with the torsion bars turned up by up to about 2 inches. Most report no rubbing; a few see light contact at full lock.
Reported on a 1999 Yukon Denali with a rear leaf added and the torsion bars raised for roughly 1.5 to 2 inches of lift. The owner trimmed a little from the bumper and running board edges to stop rubbing.
Recommended on the Tahoe Yukon Forum as clearing the control arm with 285s, and listed on a levelled 1999 Tahoe in the Custom Offsets gallery. The Tahoe shares the Yukon's four-wheel-drive hubs.
Run by a 1999 four-door Tahoe 4x4 owner on the Tahoe Yukon Forum with a 2-inch front levelling kit and a 1.5-inch rear block. It needed the front bumper bent and the rear arch trimmed.
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.
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.
Upload a photo and start with a look that suits the Yukon. Try the wheels, colour and stance before you spend on parts.
An AI preview shows the look. It cannot verify physical fitment.
These tools start with the 4WD, 16-inch alloy, standard tyre front size. Choose your own trim or axle in the calculator if it differs.
The GT was a four-wheel-drive two-door, so it uses 6x139.7 with M14x1.5 wheel nuts, the same as other 4WD GMT400 Yukons.
No. Two-wheel-drive GMT400 Yukons use a 5x127 pattern, so six-stud 4WD wheels will not fit them.
Owners commonly run 285/75 R16 on the factory 16-inch wheels with the torsion bars raised a little. Expect light rubbing at full lock on some trucks.
Wheels from a four-wheel-drive GMT400 Tahoe, Suburban or K1500 share the 6x139.7 pattern and hub, so they bolt on. Check the offset, as factory wheels varied.
Factory tyre (tire) sizes for the 1992–1999 GMC Yukon 1st gen (GMT400) are 245/75 R16 and 265/75 R16, depending on trim. Your tyre placard shows the size for your car.
Factory wheels are 16 × 7 inch, depending on trim. The stock table lists the offset for each.
78.1 mm. Aftermarket wheels with a larger bore need hub-centric rings sized to it.
This guide is a starting point, not a fitment guarantee. Specs can differ by market, trim and previous modifications. Confirm all sizes, clearances and fastener requirements with a qualified wheel and tyre professional before buying or fitting parts.
