For what reason might a vehicle fail a Class D inspection related to its tires?

A vehicle might fail a Class D inspection related to its tires due to inadequate tread depth because tire tread is critical for ensuring proper traction and handling. Tread depth significantly affects a vehicle's ability to grip the road, especially in wet or slippery conditions. Insufficient tread depth can lead to hydroplaning, reduced braking efficiency, and a higher likelihood of losing control of the vehicle. Therefore, inspectors closely check the tread depth of tires as part of the inspection process to ensure they meet safety standards and are capable of performing effectively under various driving conditions. Ensuring adequate tread depth is essential for both safety and compliance with inspection requirements.
