Complete wheel fitment specifications, compatible wheel sizes, and clearance guide
The 2024 GMC Sierra 1500 rolls off the lot with 275/60R20 tires on 8.5-inch wide wheels at a +24mm offset. This is a full-size truck platform built for towing and hauling, with tall sidewalls for load capacity and a relatively aggressive offset for a wide, planted stance. The bolt pattern is 6x139.7 (6x5.5 inches), shared across GM's full-size truck and SUV lineup.
Here are the general fitment guidelines for the 2024 GMC Sierra 1500:
| Wheel Size | Tire Size | Width Range | Offset Range | Notes |
|---|---|---|---|---|
| 18 inches | 265/70R18 | 8.0-9.0" | +15 to +30mm | Better off-road tire selection |
| 20 inches | 275/60R20 | 8.5-9.5" | +15 to +35mm | Stock size, widest options |
| 22 inches | 305/45R22 | 9.0-10.0" | +10 to +30mm | Street look, reduced sidewall |
| 24 inches | 305/35R24 | 10.0-12.0" | -12 to +20mm | Show truck, stiff ride |
Owners have developed several proven configurations:
The 6x139.7 bolt pattern means the Sierra has 6 lug holes on a 139.7mm (5.5-inch) diameter circle. This is the standard across GM's full-size lineup, so wheels are directly interchangeable with the Chevrolet Silverado 1500, GMC Yukon, Tahoe, and Suburban. Toyota Tundra and Tacoma also use 6x139.7, though hub bore sizes differ.
Cross-compatible vehicles with 6x139.7: Chevrolet Silverado 1500, Chevrolet Tahoe, GMC Yukon, Toyota Tundra, Nissan Titan. Always verify hub bore and offset.
Offset is the distance from the wheel's mounting face to the centerline. The Sierra 1500's stock offset of +24mm positions the wheel within the fender well.
Going more positive: Going more positive (+30mm or higher) tucks the wheel under the fender. This is the factory approach, designed to clear heavy-duty brake packages and allow suspension travel under load.
Going more negative: Going more negative (+10mm or lower, including 0mm and negative offsets) pushes the wheel past the fender line for the popular poke look. Below 0mm, mud flaps become legally required in most states.
Safe range for 2024 Sierra 1500: +5mm to +35mm for stock-height. Lifted trucks (3-6 inches) can go as low as -12mm.
Stock clearance: Generous. Nearly 2 inches of clearance to the fender at ride height.
What fits without modifications: 295/60R20 or 285/65R20 tires fit without body modifications on stock suspension.
What requires modification: 305/55R20 or wider benefit from front air dam trimming. 35-inch tires on lifted trucks need full suspension upgrades.
Every vehicle varies based on suspension modifications, ride height, and manufacturing tolerances. Use the WillItRub calculator to verify your specific wheel and tire combination before purchase.
