Tire sizes by trim

Recommended replacement tires

Your 2017 GMC Sierra 2500HD is a heavy-duty truck that requires E-load range tires to handle its weight and towing capacity. Here are a few popular replacement options across different price points:

• Premium: Michelin Defender LTX M/S - A long-lasting, all-season tire with excellent wet and dry traction. Expect to pay a premium for Michelin's quality and warranty.
• Mid-tier: Cooper Discoverer AT3 LT - A great all-around, all-terrain option that offers a good balance of on-road comfort and off-road capability without breaking the bank.
• Budget: General Grabber HTS60 - A solid highway-terrain tire that provides a comfortable ride and good value for the price.

When to inflate to max load psi

For heavy-duty trucks like the Sierra 2500HD, the recommended cold tire pressure on the door placard is for normal, unloaded driving. When you're towing a heavy trailer or hauling a significant load in the bed, you should inflate your rear tires to the maximum pressure indicated on the tire's sidewall. This is typically 80 psi for E-load range tires. Inflating to max load psi provides a more stable platform, reduces tire flex and heat buildup, and prevents premature wear. Once you've unloaded the truck, be sure to air the tires back down to the recommended cold pressure for a more comfortable ride and even tread wear.

Lug nut torque & pattern

• Lug nut torque: 140 lb-ft (190 Nm)
• Lug nut pattern: When tightening the lug nuts, it's important to follow a star pattern to ensure the wheel is seated evenly against the hub. For an 8-lug wheel like the Sierra 2500HD, tighten the nuts in a crisscross sequence (1-5-2-6-3-7-4-8).

Common tire issues for this vehicle

The most common tire-related issues for the 2017 GMC Sierra 2500HD are often related to improper inflation and alignment. Given the truck's weight and capability, running underinflated tires can lead to rapid and uneven wear, especially on the outer edges. It's also crucial to maintain proper alignment, as these trucks can be prone to inner tire wear if the alignment is out of spec. Regular rotations (every 5,000–7,500 miles) are essential to maximize tire life.
