Tire Sizes by Trim

Recommended Replacement Tires

Choosing the right replacement tires for your 2015 GMC Yukon is crucial for maintaining its ride quality, handling, and safety. Here are a few popular options across different price tiers:

• Michelin Defender LTX M/S (Premium Tier): A popular choice for SUVs and light trucks, offering excellent all-season traction, a comfortable and quiet ride, and long tread life. Expect to pay around $220-$280 per tire.
• Goodyear Wrangler SR-A (Mid-Range Tier): Often an OEM tire on many trucks and SUVs, the Wrangler SR-A provides a good balance of on-road comfort and light off-road capability. Prices typically range from $180-$240 per tire.
• Falken Wildpeak H/T02 (Value Tier): This tire offers a durable design and good all-season performance for highway driving, making it a solid choice for those seeking value without significant compromise. Expect to pay around $150-$200 per tire.

When to Inflate to Max Load PSI

The 2015 GMC Yukon is not a heavy-duty truck. Therefore, you should never inflate your tires to the maximum PSI indicated on the tire's sidewall for normal driving conditions. The "Max. Press." on the tire sidewall is the maximum cold inflation pressure a tire can hold when carrying its maximum load, and it's determined by the tire manufacturer, not the vehicle manufacturer.

Always refer to the tire pressure placard located on the driver's side door jamb for the recommended cold tire inflation pressures for your specific Yukon. Over-inflating your tires can lead to a harsh ride, premature tire wear in the center of the tread, and reduced traction.

Lug Nut Torque & Pattern

The lug nuts on your 2015 GMC Yukon should be torqued to 140 lb-ft (190 Nm). It is critical to tighten the lug nuts in a star or crisscross pattern to ensure even pressure and proper wheel seating. After driving approximately 50-100 miles after a wheel removal or rotation, it's a good practice to re-check the lug nut torque to ensure they haven't loosened.

Common Tire Issues for This Vehicle

Owners of the 2015 GMC Yukon sometimes report a few common tire-related issues:

• Uneven Tire Wear: This can often be attributed to improper tire inflation, lack of regular tire rotations, or an alignment issue. Regular checks of tire pressure and rotations every 5,000-7,500 miles can help mitigate this.
• Vibrations at Highway Speeds: Vibrations felt at higher speeds can indicate an issue with tire balance, a bent wheel, or a tire defect. It's important to have these checked by a professional.
• TPMS Sensor Malfunctions: While not exclusive to the Yukon, TPMS sensor batteries can eventually die, or sensors can be damaged during tire service, leading to warning lights on the dash. The 315 MHz sensors in the 2015 Yukon are generally reliable, but issues can arise with age or improper handling. If you see a TPMS warning light, have it diagnosed promptly.
