Reasons for Cracks on Tire Sidewalls?
1 Answers
Tire sidewall cracks can occur due to the following reasons: 1. Natural aging. During prolonged use, exposure to wind and sunlight causes rubber to naturally age, leading to cracks—this is a normal phenomenon. Generally, tires on vehicles over 5 years old will develop cracks, which do not affect normal usage. However, if the cracks are dense or reveal the inner tire, immediate replacement is necessary to prevent safety hazards. 2. Impact damage. When driving frequently on uneven or gravel roads, tires are inevitably subjected to impacts, which is also normal. Minor impacts do not hinder normal use, but severe impacts can reduce tire lifespan, requiring timely replacement.
