2017 GMC Yukon — Tire Size & Pressure Specs

Maintaining the correct tire and wheel specifications on your 2017 GMC Yukon is essential for safety, ride comfort, and preserving the longevity of your suspension components. Whether you are driving an SLE, SLT, or the luxurious Denali, here is the comprehensive guide to your Yukon’s tire sizes, pressures, and wheel specs.

Tire sizes by trim

The 2017 GMC Yukon came equipped with several wheel and tire combinations depending on the trim level and optional packages selected at the factory.

Always check the tire information placard located on the driver’s side door jamb to confirm the exact factory specifications for your specific vehicle.

Recommended replacement tires

Given the weight and towing capabilities of the 2017 GMC Yukon, it requires tires that can handle heavy loads while providing a quiet, comfortable ride. Here are a few top-rated replacement options:

• Michelin Defender LTX M/S (Premium): The gold standard for full-size SUVs. Offers exceptional tread life, excellent wet traction, and a quiet ride.
• BFGoodrich All-Terrain T/A KO2 (Mid-High): A great option if you take your Yukon off-road or deal with heavy snow. Very durable but will reduce fuel economy slightly.
• Falken Wildpeak A/T3W (Mid-Tier): An excellent balance of off-road capability and on-road manners at a more affordable price point than the KO2.
• Kumho Crugen HT51 (Budget): A solid, budget-friendly highway terrain tire that delivers reliable all-season performance and a smooth ride.

When to inflate to max load psi

While the 2017 GMC Yukon is a half-ton platform (not an HD truck like a Sierra 2500), it still boasts impressive towing capacity. The standard recommended tire pressure is 35 PSI. However, if you are towing a heavy trailer near the maximum towing capacity or carrying a full payload of passengers and cargo, you may need to increase your rear tire pressure to accommodate the extra weight.

Typically, increasing the rear tires to 38-40 PSI (never exceeding the maximum cold PSI listed on the tire sidewall, which is usually 44 or 50 PSI for standard load tires) will reduce sidewall flex, improve towing stability, and prevent tires from overheating. Once the load is removed, bleed the pressure back down to 35 PSI.

Lug nut torque & pattern

• Bolt Pattern: 6x139.7 mm (also known as 6x5.5 inches)
• Lug Nut Thread Size: M14 x 1.5
• Lug Nut Torque: 140 lb-ft (190 Nm)

Note: Always use a calibrated torque wrench when tightening lug nuts. Overtightening can warp the brake rotors, and undertightening can result in wheel detachment. Re-torque the lug nuts after 50-100 miles of driving following a wheel installation.

Common tire issues for this vehicle

• Uneven Wear on 22-inch Wheels: The optional 285/45R22 tires on the Denali trims have shorter sidewalls, making them more susceptible to alignment issues and inner-edge wear. Regular alignment checks every 10,000 miles are highly recommended.
• Magnetic Ride Control Interaction: For Denali trims equipped with Magnetic Ride Control, worn or out-of-balance tires can trigger unusual vibrations that mimic suspension failure. Always ensure tires are road-force balanced.
• TPMS Sensor Battery Failure: The 315 MHz TPMS sensors on the 2017 model are approaching the end of their 7 to 10-year battery life span. If you are replacing your tires soon, it is wise to replace all four TPMS sensors simultaneously to avoid future labor charges.
