Tire size comparison
Diameter change, speedometer error, and whether it will rub.
Large enough that rubbing at full steering lock or under suspension compression is common. Usually solved by removing the front mud flaps or trimming the air dam.
- Sits 0.46" higher at the axle and needs 0.46" more clearance at the top of the wheel well.

Wheel fitment on the Chevrolet Silverado 1500
Any wheel you put these tires on has to match 6x120mm with a 66.9mm center bore. Aftermarket wheels are frequently bored larger to fit several vehicles; those need hub-centric rings so the hub carries the vehicle weight rather than the M14 x 1.5 studs.
Offset is the other half of fitment and the one that decides rubbing. A lower or negative offset pushes the wheel outward for a wider stance, which buys inner clearance at the steering knuckle but moves the tire toward the fender lip and increases load on the wheel bearing. If you are going wider, expect to think about offset at the same time.
Common questions
What size tires does a Chevrolet Silverado 1500 come with?
The 2019–2025 Chevrolet Silverado 1500 ships with sizes from 255/70R17 on base trims up to 275/60R20 on LTZ, High Country 20". Overall diameter across the range runs 31.1 to 33.0 inches, which is why wheel size alone tells you very little about how tall the tire is.
What is the biggest tire I can fit on a stock Chevrolet Silverado 1500?
Coming from a common 275/65R18 at 32.1 inches tall, staying within about 3% means roughly 33.0 inches — one step up. Owners routinely go further with the front mud flaps removed and the air dam trimmed, but past 5% you are into leveling kit and offset territory. Run your exact pair through the calculator above.
Do I need to keep the same wheel size on a Chevrolet Silverado 1500?
No, as long as the new wheel matches the 6x120mm bolt pattern and the 66.9mm center bore, clears the brake calipers, and the total tire diameter stays close to stock. Going down a wheel size with a taller sidewall to keep the same overall diameter is a common and generally sound swap.
