Tire sizes by trim

Recommended replacement tires

When it's time for new tires on your 2021 Chevrolet Equinox, you have a wide range of excellent options. Here are a few popular choices across different price tiers, known for their performance, longevity, and comfort.

• Michelin Defender T+H (Premium Tier): These tires are a top pick for all-season performance, offering excellent wet and dry traction, a comfortable ride, and a long tread life. They are a great investment for drivers who prioritize safety and durability.
• Goodyear Assurance ComforTred Touring (Mid-Tier): As the name suggests, these tires excel in providing a very comfortable and quiet ride. They also deliver reliable all-season traction and good treadwear, making them a solid all-around choice for daily driving.
• General Altimax RT43 (Value Tier): The Altimax RT43 is a fantastic value option. It provides competitive all-season grip, a smooth ride, and impressive tread life for its price point. It's a popular choice for those seeking quality without breaking the bank.

Always ensure your chosen replacement tires match the OEM tire size, load index, and speed rating specifications for your specific Equinox trim level.

When to inflate to max load psi

The 2021 Chevrolet Equinox is a passenger SUV, not a heavy-duty truck. Therefore, you should never inflate your tires to the "max load" pressure listed on the tire's sidewall. This pressure is the maximum a cold tire can hold to support its maximum rated load and is generally too high for everyday driving in a vehicle like the Equinox.

Always refer to the tire pressure placard located on the driver's side door jamb for the recommended cold tire inflation pressure. For the 2021 Equinox, this is typically 35 PSI for all four tires, regardless of tire size.

Lug nut torque & pattern

Proper lug nut torque is crucial for wheel safety and to prevent issues like warped brake rotors. For the 2021 Chevrolet Equinox, the recommended lug nut torque specification is 100 lb-ft (135 Nm).

When tightening lug nuts, always follow a star or criss-cross pattern. This ensures even pressure distribution on the wheel hub assembly. Tighten the nuts in stages, gradually increasing the torque until the final specification is reached.

Common tire issues for this vehicle

The Chevrolet Equinox is a popular SUV, and while generally reliable, some common tire-related issues owners might encounter include:

• Uneven Tire Wear: This can often be attributed to improper tire inflation (under- or over-inflation), misaligned suspension, or unbalanced wheels. Regular tire rotations (every 5,000-7,500 miles) and alignments are key to preventing premature and uneven wear.
• TPMS Sensor Issues: The TPMS (Tire Pressure Monitoring System) in the Equinox operates at 315 MHz. Occasionally, sensors can fail, especially after several years or if the battery within the sensor dies. This will usually trigger a warning light on your dashboard.
• Vibrations at Highway Speeds: This is often a sign of unbalanced wheels or, less commonly, a bent wheel or tire defect. If you experience vibrations, have your tires and wheels inspected by a professional.

Regular tire maintenance, including consistent pressure checks, rotations, and alignments, will help you avoid most common tire issues and extend the life of your tires.
