Reasons for Cracks on the Sidewall of Tires

[McLane]

Reasons for cracks on the sidewall of tires: 1. Poor maintenance or driving on gravel roads and construction sites, leading to contact with hard objects that cause damage to the inner layers of the tire under heavy pressure; 2. Long-term use of the tire causing rubber aging, resulting in numerous fine cracks on the sidewall. Tires older than 4 years often exhibit this phenomenon. Methods to address cracks on the sidewall of tires: 1. Outer edge wear: If significant wear is observed on the outer edge of the tire in the direction of travel, it indicates that the tire is frequently underinflated. 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 such as shock absorbers, bearings, and ball joints. It is recommended to inspect the wear condition of the suspension system and replace worn parts before changing the tire.
