What is the classification for a defect in tire tread depth?

A defect in tire tread depth is classified as a major issue because it significantly impacts the vehicle's safety and performance. Adequate tire tread depth is crucial for ensuring proper traction, stability, and control, especially in adverse weather conditions such as rain or snow. Insufficient tread can lead to hydroplaning, longer stopping distances, and overall reduced handling capability, which can greatly increase the risk of accidents.

This classification aligns with safety regulations that recognize tire maintenance as a fundamental aspect of vehicle operation. Therefore, any concern regarding tread depth is taken seriously as it directly influences the vehicle's ability to perform safely on the road. The classification aims to highlight the necessity of addressing such defects promptly to maintain safe driving conditions.
