Chevrolet Silverado 1500 3rd gen (K2XX) wheel fitment
The 2014–2018 Silverado 1500 left the factory on 17, 18, 20 or 22-inch wheels, all on the same six-stud hub. Most owners either fit a levelling kit and slightly taller tyres on the factory 20s, or go to 17 or 18-inch wheels with all-terrains for a lifted look.

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, factory 17-inch wheels
- Front and rear
- 17 × 8 inch, ET24 · 285/70 R17
RealTruck lists 285/70 R17 on the factory 17s once the front is levelled by 2 inches. This tyre is about 6% taller than the WT's 255/70 R17, so the speedometer will read low.
3.5-inch lift on 18x9 wheels
- Front and rear
- 18 × 9 inch, ET18 · 285/65 R18
RealTruck lists 285/65 R18 on 18x9 wheels at ET0 to ET20 for 2014–2018 trucks with a 3.5-inch lift; this entry uses ET18. Follow the lift maker's wheel requirements.
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 2014–2018 Silverado 1500s use 6x139.7 with a 78.1 mm centre bore and M14x1.5 studs, so factory wheels from this generation and the 2019-on T1 trucks share the same mounting dimensions. Check brake clearance and the nut seat before swapping.
- Sources disagree on some factory offsets. Two fitment databases give ET24 for the 17-inch wheel and ET27 for the 20-inch, while an OEM wheel supplier lists ET28 and ET24. Read the offset stamped on your wheel if it matters.
- Levelling kits change the front ride height only. Taller or wider tyres on factory-offset wheels can touch the upper control arm, so check at full lock before driving far.
- GM's figure is 140 lb ft, about 190 Nm.
- 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.
