2022 GMC Yukon — Tire Size & Pressure Specs

As an ASE-certified master technician, I regularly service full-size SUVs like the 2022 GMC Yukon. Getting the right tires, keeping them properly inflated, and maintaining the correct torque specifications are critical for vehicle safety, ride comfort, and tread life. Below is your comprehensive guide to the 2022 GMC Yukon’s tire sizes, pressures, and wheel specifications.

Quick Answer: 2022 GMC Yukon Tire & Wheel Specs

Here are the baseline specifications for the 2022 GMC Yukon. Always verify your specific vehicle's specs by checking the tire information placard located on the driver’s side door jamb.

• OEM Tire Size: 275/65R18 (Base SLE/SLT) up to 275/50R22 (Denali)
• Recommended Cold Tire Pressure: 35 PSI Front / 35 PSI Rear (Standard load)
• Bolt Pattern: 6x139.7 mm (also known as 6x5.5")
• Wheel Size: 18x8.5", 20x9", or 22x9" (Offset varies from +24mm to +28mm)
• Load Index / Speed Rating: 116T (18-inch), 115T or 115S (20-inch), 111H (22-inch)
• Spare Tire Size: 265/70R17 (or a matching full-size spare depending on the towing package/trim)
• TPMS Frequency: 433 MHz

Tire Sizes by Trim

The 2022 GMC Yukon is available in a variety of trims, ranging from the practical SLE to the luxurious Denali and the off-road-focused AT4. Each trim utilizes different wheel and tire combinations.

Recommended Replacement Tires

Because the Yukon is a heavy, body-on-frame SUV, you need tires that can support its weight while providing a smooth, quiet ride. Here are a few technician-recommended options:

• Premium / Best Overall: Michelin Defender LTX M/S – Exceptional tread life, fantastic wet traction, and very quiet on the highway. (Premium Tier)
• Off-Road / All-Terrain: Falken Wildpeak A/T3W – Perfect for the AT4 trim or anyone looking to take their Yukon off-road without sacrificing daily driving comfort. (Mid-Range Tier)
• Highway / Value: Cooper Discoverer HT3 – A reliable, durable highway tire that offers good performance and longevity at a more accessible price point. (Value Tier)

When to Inflate to Max Load PSI

While the Yukon is a full-size SUV and not a heavy-duty (HD) 2500/3500 pickup, it shares a chassis platform with the Sierra 1500 and is often used for heavy towing.

The standard recommended pressure is 35 PSI. However, if you are towing a heavy travel trailer, boat, or hauling a cabin full of passengers and cargo near the Gross Vehicle Weight Rating (GVWR), you should consult your owner's manual. For XL models or when fully loaded, you may need to increase the rear tire pressure closer to 39–41 PSI (never exceeding the max cold pressure stamped on the tire sidewall, typically 44 or 51 PSI for standard load tires) to reduce sidewall flex and prevent heat buildup. Always drop the pressure back to 35 PSI once the load is removed to prevent uneven center tread wear.

Lug Nut Torque & Pattern

Proper wheel installation is a matter of safety. If lug nuts are under-torqued, the wheel can come loose. If over-torqued, you risk warping the brake rotors or snapping a stud.

• Lug Nut Torque: 140 lb-ft (190 Nm)
• Thread Size: M14 x 1.5
• Tightening Pattern: Always use a 6-lug star (crisscross) pattern. Seat the lug nuts snugly by hand, then torque them in sequence to ensure the wheel sits perfectly flush against the hub.

Common Tire Issues for this Vehicle

1. Outer Edge Wear: Because the Yukon is a heavy, tall vehicle, aggressive cornering often scrubs the outer shoulders of the front tires. Regular tire rotations (every 5,000 to 7,500 miles) are essential.
2. Cupping/Scalloping: If the heavy-duty shocks or struts begin to wear out, or if the wheels are out of balance, the tires may begin to "cup" (develop high and low spots). This creates a loud, rhythmic humming noise at highway speeds.
3. TPMS Sensor Failures: The 433 MHz sensors have internal batteries that typically last 5-7 years. While your 2022 model is currently fine, expect to replace these sensors when you get your second or third set of replacement tires.
