What are the causes and solutions for cracks on the sidewall of tires?

[VanAshley]

Tire sidewall cracks causes: 1. Poor maintenance or driving on gravel roads and construction sites, where hard objects come into contact with the tire, causing damage to the inner layer under heavy pressure; 2. Long-term use leading to rubber aging, resulting in numerous fine cracks on the sidewall, a common phenomenon for tires older than 4 years. Solutions for tire sidewall cracks: 1. Outer edge wear: If significant wear is observed on the outer edge of the tire along the driving direction, it indicates frequent under-inflation. Inflate according to the "highway" standard, which is 30 kPa higher than the normal standard; 2. Convex and wavy wear: If the tire shows wavy wear around its circumference, it suggests severe wear of components like shock absorbers, bearings, and ball joints. It is recommended to inspect the suspension system and replace worn parts before changing the tire.
