Tire Sizes by Trim

The 2022 GMC Acadia comes with a couple of different tire and wheel options depending on the trim level:

It's always best to check your vehicle's door placard for the exact tire size and pressure recommendations for your specific Acadia.

Recommended Replacement Tires

When it comes time to replace the tires on your 2022 GMC Acadia, you have a wide range of options. Here are a few popular choices across different price tiers:

• Premium Option: Michelin Defender LTX M/S

  • A top-rated all-season tire known for its exceptional longevity, comfort, and all-weather traction. Excellent for those who prioritize a smooth, quiet ride and long tread life. (~$220-$280 per tire)

• Mid-Range Option: Continental CrossContact LX25

  • Offers a great balance of performance, comfort, and value. This all-season tire provides reliable wet and dry traction, good tread life, and a comfortable ride. (~$180-$240 per tire)

• Value Option: Cooper Discoverer HTP II

  • A solid choice for budget-conscious buyers looking for reliable all-season performance. It delivers good handling and a comfortable ride for its price point. (~$150-$200 per tire)

• All-Terrain Option (for AT4): Falken Wildpeak A/T Trail

  • If you have the AT4 trim or simply desire more off-road capability for light trails without sacrificing too much on-road comfort, the Wildpeak A/T Trail is a great crossover all-terrain tire. (~$190-$250 per tire)

When to Inflate to Max Load PSI

Unlike heavy-duty trucks designed to carry significant loads, the 2022 GMC Acadia is a mid-size SUV and does not typically require inflation to a "max load" PSI. The recommended tire pressure found on your door placard (usually 35 PSI for the Acadia) is designed to provide the best balance of safety, ride comfort, fuel efficiency, and tire longevity for all normal driving conditions, including when the vehicle is fully loaded with passengers and cargo within its Gross Vehicle Weight Rating (GVWR).

Always adhere to the pressures specified on your vehicle's door jamb sticker. Overinflating your tires beyond the recommended pressure can lead to a harsher ride, premature tire wear in the center of the tread, and potentially compromise handling.

Lug Nut Torque & Pattern

Proper lug nut torque is crucial for wheel retention and safety. For the 2022 GMC Acadia, the lug nut specifications are:

• Lug Nut Torque: 140 lb-ft (190 Nm)
• Lug Nut Pattern: Always tighten lug nuts in a star or criss-cross pattern. This ensures even seating of the wheel against the hub and prevents warping of the brake rotor. Start by hand-tightening all lug nuts, then progressively tighten them to the specified torque in the star pattern.

It's good practice to re-check the lug nut torque after the first 50-100 miles of driving after a wheel has been removed and reinstalled.

Common Tire Issues for This Vehicle

While the 2022 GMC Acadia is generally reliable, some common tire-related considerations can arise:

• Uneven Tire Wear: Misalignment, improper tire pressure, or worn suspension components can lead to uneven tire wear (e.g., inner or outer edge wear, feathering). Regular tire rotations (every 5,000-7,500 miles) and alignment checks can help mitigate this.
• TPMS Sensor Issues: The TPMS (Tire Pressure Monitoring System) uses sensors in each wheel to monitor tire pressure. While generally reliable, these sensors can occasionally fail due to battery depletion (they have an internal battery that lasts several years) or damage during tire changes. The 2022 Acadia uses a 315 MHz frequency for its TPMS sensors.
• Tire Noise: As tires wear, they can sometimes become louder, especially if uneven wear patterns develop. Choosing a quality tire with good noise reduction characteristics can help maintain a quiet cabin.
• Pothole Damage: Low-profile tires, like the 235/55R20 option, can be more susceptible to damage from potholes, leading to sidewall bulges or bent wheels. Driving cautiously on rough roads is advisable.

Maintaining proper tire pressure, rotating your tires regularly, and addressing any alignment issues promptly will help ensure optimal tire life and performance for your 2022 GMC Acadia.
