What are the causes of inner tire wear on rear wheels?

[FelicityFitz]

The causes of inner tire wear on rear wheels are: 1. Insufficient toe-in or camber angle of steering wheels, which indicates inaccurate four-wheel alignment; 2. Failure to perform dynamic balancing after tire repair or replacement; 3. Excessive differences in tire pressure. The functions of tires are: 1. Transmitting driving force, braking force, and steering force to achieve vehicle operation; 2. Supporting vehicle load; 3. Reducing and absorbing vibrations and impacts during driving to prevent severe vibrations from damaging automotive components. Tire maintenance methods include: 1. Regularly removing stones from tire treads; 2. Minimizing prolonged exposure to sunlight; 3. Timely checking tire pressure; 4. Paying attention to suspension maintenance; 5. Periodically inspecting front wheel alignment; 6. Adopting proper driving techniques by choosing appropriate road surfaces, avoiding objects that may puncture or scratch tires, and steering clear of chemical spills that could corrode tires.

I've noticed that inner tire wear on the rear wheels is quite common, mainly related to aging suspension systems. Issues like worn bushings in rear suspension arms or deformed links can cause excessive wheel camber, accelerating inner tire wear. It may also be connected to improper wheel alignment - incorrect parameters can lead to uneven tire stress. Additionally, insufficient or uneven tire pressure makes tires more prone to deformation from compression. Last time I ignored this issue, the tires wore out quickly - not only costing more for replacements but also compromising driving safety, potentially causing vibrations or even blowouts at high speeds. For prevention, I regularly check tire pressure for consistency, perform wheel alignment checks every six months, and promptly visit professional shops for suspension adjustments when issues are detected.

During vehicle repairs, I've encountered numerous cases of excessive inner tire wear on rear wheels. The most common causes are damaged chassis components, such as aged rear suspension arm bushings or cracked bushings, which increase wheel camber and cause tire scrubbing. It could also result from unrepaired frame deformation after a collision. Additionally, incorrect wheel alignment parameters like toe or camber settings often lead to inner edge wear. For diagnosis, first use an alignment machine to check angle accuracy, then inspect suspension arms and links for looseness. As prevention, advise owners to avoid neglecting rough road conditions, perform regular maintenance checks to reduce bushing fatigue. Delayed repairs may damage wheel bearings or speed sensors, increasing repair costs.

After driving for so many years, I've found that rear tire wear issues mostly stem from alignment deviations or tire pressure problems. When tire pressure is too low, the inner side bears more force and wears out faster. Aging suspension components like rubber bushings can also cause the wheels to tilt inward. If detected early, it's easy to fix with an alignment adjustment or replacing the bushings. Delaying repairs accelerates tire wear, making the car shake more and less stable at high speeds, with higher risks when turning in the rain.
