GMC Sierra 1500 Tire Size Chart by Year and Trim
The GMC Sierra 1500 is mechanically nearly identical to the Chevrolet Silverado 1500, sharing the same frame, drivetrain, and wheel specifications. The differentiation is primarily in styling, trim levels, and interior appointments — Denali is GMC's top-tier luxury trim and has no Silverado equivalent.

Frequently Asked Questions: GMC Sierra 1500 Tires
Are GMC Sierra and Chevy Silverado wheels interchangeable?
Yes, completely. Both trucks share the 6×139.7mm bolt pattern, 78.1mm hub bore, and nearly identical offset ranges. Denali wheels fit Silverado, High Country wheels fit Sierra, AT4 wheels fit Trail Boss, and vice versa. TPMS sensors are GM-universal (315 MHz), so they transfer without relearning in most cases.
What tire size comes on the 2024 GMC Sierra AT4?
The 2024 GMC Sierra AT4 comes with 275/65R18 all-terrain tires (approximately 32" diameter) on 18" wheels. The more aggressive AT4X variant uses 275/70R18 (33") tires, and the AT4X AEV Edition steps up to 33×12.5R18 with serious off-road tread. All AT4 trims include a 2" factory lift.
How much do Sierra Denali tires cost?
Sierra Denali 22" tires (275/50R22) typically cost $220-400 per tire, with installation running another $30-50 per tire. A full set replacement on a Denali typically costs $1,000-1,700 installed. The Denali Ultimate uses premium OEM tires (often Goodyear Eagle Touring) that cost at the upper end of that range.
Can I put Denali 22" wheels on my SLE Sierra?
Yes. All Sierra 1500 trims from 2014-2026 share the same bolt pattern, hub bore, and compatible offset range. OEM Denali 22" wheels are a popular upgrade for SLE/SLT owners because the used market is large — expect to pay $400-600 per wheel for clean takeoffs. TPMS sensors transfer directly.
What is the bolt pattern on a GMC Sierra 1500?
All 2014-2026 GMC Sierra 1500 trucks use a 6×139.7mm (6×5.5") bolt pattern with 78.1mm center bore. This is the GM full-size truck standard and is shared across the entire GM 1500-series lineup including Silverado, Tahoe, Yukon, Suburban, and Escalade.
Does the Sierra EV use different tires than the gas Sierra?
Yes. The Sierra EV Denali (2024+) uses specialized 275/55R22 EV-optimized tires designed for the additional weight of the battery pack (approximately 9,000 lbs curb weight vs 5,400 lbs for gas Sierra Denali). Standard truck tires will wear significantly faster on the EV. Higher tire pressure (42-44 PSI) is also required.
