Explained in our guides
Read these before choosing wheels for the Silverado 1500: 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.

Levelled all-terrain
- Front and rear

Listed by RealTruck for the GMT800 with a 2-inch levelling kit. Check bumper and liner clearance through steering lock and suspension compression; tyre shape affects trimming.
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
- These hub dimensions apply to the six-stud 1500, not the eight-stud 1500HD, 2500 or 3500.
- 2007 includes both GMT800 Classic and the newer GMT900. Confirm the body generation when ordering.
- GM specifies 190 Nm for the wheel nuts. Use the nut seat required by the selected wheel.
- A levelling kit does not establish clearance at full compression; test the tyre against the bumper, liner and suspension.
- 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.
