What Causes Inner Tire Wear on Rear Wheels?

[VonCaleb]

The reasons for inner tire wear on rear wheels are: 1. Incorrect toe-in or insufficient camber angle of steering wheels, which falls under inaccurate four-wheel alignment; 2. Failure to perform wheel balancing after tire repair or replacement. To address inner tire wear, specific analysis is required for each case. If caused by inaccurate four-wheel alignment, a four-wheel alignment should be performed; if caused by wheel balancing failure, wheel balancing should be done. Taking wheel balancing as an example, since tire mass is not perfectly uniform, when the vehicle travels at high speeds, the uneven mass distribution is amplified, making the vehicle prone to deviation. Therefore, balancing weights are added to the tires to achieve balance. Balancing weights are present on both the inner and outer sides of the tire. If the vehicle frequently travels on bumpy roads causing the outer balancing weights to fall off, it can lead to inner tire wear.
