Rear tires being worn down on the inner side of the tires?

If you are experiencing uneven tire wear on the inner side of the rear tires on your 2003 Chevrolet Cavalier, there are a few potential causes to consider:

Wheel Alignment: Improper wheel alignment can cause uneven tire wear, particularly on the inner or outer edges of the tires. It is possible that your vehicle's rear wheels are misaligned, leading to the specific wear pattern you described. Have a professional mechanic perform a four-wheel alignment to ensure the wheels are properly aligned.

Suspension Components: While you mentioned that you replaced the rear struts, it's worth checking the condition of other suspension components, such as control arms, bushings, and trailing arms. Worn or damaged suspension components can affect wheel alignment and lead to uneven tire wear. A thorough inspection by a mechanic should help identify any issues.

Tire Inflation: Incorrect tire inflation can contribute to uneven tire wear. Make sure that your rear tires are inflated to the recommended pressure specified by the vehicle manufacturer. Regularly check and adjust the tire pressure to maintain proper inflation.

Driving Habits: Aggressive driving, excessive cornering, or consistently carrying heavy loads can put additional stress on the rear tires and contribute to uneven wear. Consider adjusting your driving habits to minimize strain on the tires.
