2025 GMC Yukon Tire Size & Pressure Guide

As an ASE-certified master technician, I’ve serviced countless full-size GM SUVs over the years. The 2025 GMC Yukon is a massive, highly capable family hauler that demands the right set of tires to maintain its smooth ride, towing stability, and all-weather capability. Because of its weight and independent rear suspension, keeping your Yukon's tires properly inflated and rotated is essential for maximizing tread life.

Below is your comprehensive guide to the 2025 GMC Yukon tire sizes, pressures, wheel specs, and torque requirements.

Quick Answer: 2025 GMC Yukon Tire & Wheel Specs

Here are the baseline specs you need to know before buying new tires or swapping wheels on your 2025 Yukon:

• OEM Tire Size: 275/65R18 (Base), with 275/60R20, 275/50R22, and 275/40R24 as trim-dependent options.
• Recommended Cold Tire Pressure: 35 PSI Front / 35 PSI Rear (check driver's side door placard to confirm for your specific trim/wheel combo).
• Bolt Pattern: 6x139.7 mm (6x5.5 inches).
• Wheel Size & Offset: 18x8.5, 20x9, 22x9, or 24x9. Factory offset typically ranges from +24mm to +28mm.
• Load Index / Speed Rating: 115T to 116H (Varies by tire size; always match or exceed the factory load rating for a heavy SUV).
• Spare Tire Size: 265/70R17 (Temporary/compact matching outer diameter) or a matching full-size spare on certain AT4/Denali packages.
• TPMS Sensor Frequency: 433 MHz.

Tire Sizes by Trim

The 2025 GMC Yukon is offered in several trims, from the base Elevation to the off-road-focused AT4 and the luxurious Denali Ultimate. The wheel and tire packages vary significantly across the lineup.

Recommended Replacement Tires

Given the 2025 Yukon’s nearly 6,000-pound curb weight, you need a tire with a strong sidewall and excellent wet traction. Here are my top recommendations based on years in the shop:

• Premium / Best Overall: Michelin Defender LTX M/S 2 An industry standard for heavy SUVs and half-ton trucks. They offer a buttery smooth ride, exceptional wet braking, and last incredibly long even under heavy loads.
• Off-Road / All-Terrain (Great for AT4): BFGoodrich All-Terrain T/A KO2 (or KO3) If you take your Yukon off the beaten path or deal with heavy snow, these provide aggressive traction without howling on the highway.
• Mid-Tier / Value All-Season: Cooper Discoverer HT3 A highly capable highway-terrain tire that provides a quiet ride and good treadwear at a more approachable price point.

Lug Nut Torque & Pattern

Properly torquing the wheels on a full-size SUV is a major safety concern. Over-tightening can warp brake rotors, while under-tightening can lead to a loose wheel.

• Lug Nut Torque: 140 lb-ft (190 Nm).
• Tightening Pattern: 6-lug crisscross (star) pattern.
• Socket Size: 22mm or 7/8".

Always use a calibrated torque wrench and re-check the torque after 50 to 100 miles of driving when installing new wheels or after a tire rotation.

Common Tire Issues for this Vehicle

While the modern independent rear suspension on the GMC Yukon provides a phenomenal ride, it also means there are more alignment angles to keep in check compared to older solid-axle generations.

1. Inner/Outer Edge Wear: Because the Yukon is so heavy, slight misalignments (especially toe angles) will scrub the edges of the front tires very quickly. I highly recommend an alignment check every 12,000 to 15,000 miles.
2. Premature Wear on 22" and 24" Wheels: The massive 22-inch and 24-inch wheels on the Denali and Denali Ultimate look great, but they come with thinner tire sidewalls. These lower-profile tires tend to wear out faster (often lasting only 30,000 to 40,000 miles) and are much more susceptible to pothole damage.
3. TPMS Sensor Battery Life: While it won't be an issue on a brand new 2025 model for a few years, expect the 433 MHz TPMS sensors to require replacement around the 7-to-10-year mark when their internal batteries die.
