What tires come on GMC 2500?
Trucks labeled GMC 2500, most commonly the Sierra 2500HD, do not have a single tire specification. The original equipment tires vary by year, trim level, and optional packages. In recent models, you’ll typically see 17– to 20-inch wheel configurations with several common tire sizes. Always check the door placard or window sticker for your exact size.
OEM tire configurations by wheel size
The following sizes reflect common stock configurations seen on Sierra 2500HD trucks with different wheel diameters. Exact sizes can vary by model year and trim, so verify your specific vehicle.
- 17-inch wheels: LT245/75R17 or LT265/75R17 — frequently found on base or work-focused trims.
- 18-inch wheels: LT275/65R18 or LT265/70R18 — common on mid-level trims with upgraded ride and payload options.
- 20-inch wheels: LT275/60R20 or LT275/55R20 — typical on higher trims or when an appearance package is chosen.
These examples illustrate typical OEM tire sizes used with different wheel options. Your exact tire size may differ, so always confirm with the vehicle’s official placard or build sheet.
Guidance for replacing tires on the Sierra 2500HD
When selecting replacement tires, consider the truck’s heavy-duty duties, payload, and towing needs. The right choice balances load capacity, tread pattern for your climate, and wheel compatibility. The Sierra 2500HD often benefits from tires designed for durability and stability under heavy loads, with options spanning all-season, all-terrain, and winter tires.
- Determine your typical use: on-road commuting, mixed terrain, or off-road and worksite conditions.
- Check load rating and speed rating to ensure they meet or exceed OEM specifications for payload and towing.
- Maintain proper tire pressure and wear evenness; consider a 5–6 year replacement horizon regardless of tread depth, depending on usage.
- If you plan to upgrade wheel size, verify that the new size maintains acceptable sensor accuracy and ground clearance, and consider reprogramming if needed.
Consult GM’s guidelines or a trusted tire professional to confirm compatibility with your drivetrain (gas or diesel) and to ensure safe, reliable performance.
Where to find the exact tire size for your GMC Sierra 2500HD
The most reliable source for your exact OEM tire size is the driver’s door placard (often on the door jamb) and the owner’s manual. The build sheet or window sticker, available from GM or a dealership, also lists the original equipment tire size. If you’re purchasing a used truck, verify the size on the tire sidewalls and cross-check it with the placard to avoid mismatches.
