Causes of Inner Tire Wear on All Four Tires?

[MacStella]

Severe inner tire wear can occur during vehicle operation. Tire Pressure Issues: Insufficient tire pressure leads to wear on both side edges, while overinflation causes wear in the center of the tread. Failure to rotate tires regularly may also result in uneven pressure between rear dual tires, accelerating wear on the higher-pressure tire during driving. Therefore, it's advisable to check whether both side tires have normal pressure. Abnormal Four-Wheel Alignment Data: For vehicles driven for some time, changes in four-wheel alignment data may cause deviation. In such cases, a four-wheel alignment service at a 4S shop or repair facility is necessary. Chassis Problems: Daily driving causes component wear and aging, leading to changes in major chassis parts that may result in tire deviation and wear. Professional adjustment or part replacement at a 4S shop is required.
