2025 GMC Acadia — Tire Size & Pressure

As an ASE-certified master technician, I know that maintaining the right tire specs on your vehicle is one of the most critical aspects of safety, fuel economy, and handling. The 2025 GMC Acadia, recently redesigned to offer more space and capability, demands specific tire and wheel requirements to keep its advanced all-wheel-drive systems and suspension performing as engineered.

Whether you are looking to replace worn-out factory tires or just checking your pressures before a long family road trip, this guide covers everything you need to know about the 2025 GMC Acadia’s tire and wheel specifications.

Quick answer

Here are the baseline factory tire and wheel specifications for the 2025 GMC Acadia:

• OEM tire size: 255/65R18 (Base/Elevation), 265/65R18 (AT4), up to 275/45R22 (Denali)
• Recommended cold tire pressure: 35–36 PSI (front & rear, refer to the driver’s side door jamb placard for your specific trim)
• Bolt pattern: 6x120 mm
• Wheel size: 18x8.0 to 22x8.5 (Offset generally between +45mm to +50mm)
• Load index/Speed rating: 109H to 111H (varies by size/trim)
• Spare tire size: T135/70R18 (Compact spare)
• TPMS frequency: 433 MHz

Tire sizes by trim

Depending on the trim level you chose, the 2025 Acadia rolls out of the factory with different wheel and tire setups. Always verify your specific size on the tire sidewall before purchasing replacements.

Trim Level	Standard Tire Size	Optional/Upgrade Size
Elevation	255/65R18	255/55R20
AT4	265/65R18 (All-Terrain)	N/A
Denali	255/55R20	275/45R22

Recommended replacement tires

When it is time to replace your tires, choosing the right rubber is essential for maximizing the ride quality of this premium SUV. Here are my top recommendations based on performance and budget:

• Michelin Defender LTX M/S 2 (Premium): Excellent tread life, incredibly quiet, and provides fantastic all-season traction. Best for highway driving and longevity.
• Falken Wildpeak A/T Trail (Mid-Range/All-Terrain): Perfect for the AT4 trim or anyone wanting a more aggressive look without sacrificing on-road comfort. Excellent wet and light snow performance.
• Continental CrossContact LX25 (Mid-Range): A great balance of ride comfort, wet braking, and fuel efficiency.
• Cooper Endeavor Plus (Budget-Friendly): A solid entry-level all-season tire that delivers reliable performance and decent wear for the price point.

When to inflate to max load psi

Note: The 2025 GMC Acadia is a mid-size/large crossover SUV, not a Heavy-Duty (HD) truck.

Unlike HD trucks (like the Sierra 2500HD) which require adjusting rear tire pressures to 80 PSI when towing heavy fifth wheels, the Acadia does not have a "max load" dual-pressure requirement for daily vs. towing use. You should maintain the 35–36 PSI cold pressure listed on your door placard at all times.

If you are towing up to the Acadia's maximum capacity (up to 5,000 lbs with the proper tow package), ensure your tires are at the recommended placard pressure before they heat up. Do not inflate them to the "Max Press" listed on the tire sidewall (usually 44 or 51 PSI), as this will cause uneven wear, a harsh ride, and reduced traction.

Lug nut torque & pattern

Proper wheel installation is vital to prevent warped brake rotors or a catastrophic wheel separation.

• Bolt Pattern: 6x120 mm
• Lug Nut Torque: 140 lb-ft (190 Nm)
• Thread Size: M14 x 1.5

Always use a calibrated torque wrench in a star or crisscross pattern when tightening lug nuts. I highly recommend re-torquing the wheels after 50 to 100 miles of driving anytime a wheel has been removed.

Common tire issues for this vehicle

While the newest generation of the Acadia is quite robust, there are a few tire-related things owners should watch out for:

1. Uneven shoulder wear on 22-inch wheels: The low-profile tires on the Denali trim are more susceptible to poor alignment and lack of rotation. Make sure you rotate them every 5,000 to 7,500 miles.
2. Pothole damage: Similarly, the 22-inch wheel option has very little sidewall cushion. Drivers in areas with poor roads may experience impact breaks or bent rims more frequently.
3. TPMS sensor battery life: While not an immediate issue for a 2025 model, GM's 433 MHz sensors typically last 5 to 7 years. If one fails down the road, it's usually best to replace all four at your next tire change.
