What is the minimum allowable depth of the tires on the rear axle of a school bus?

The minimum allowable depth of the tires on the rear axle of a school bus is set at 2/32 of an inch. This specification is important for ensuring adequate traction and safety while driving. Tires with insufficient tread depth can significantly reduce the performance of the vehicle, especially in wet or slippery conditions.

In the context of school buses, which are often responsible for transporting children, maintaining the required tire tread depth is crucial for the safety of both the passengers and other road users. Adhering to this standard minimizes the risk of accidents due to tire hydroplaning or loss of grip on the road.

Furthermore, regulatory standards and vehicle maintenance guidelines emphasize the importance of regularly checking tire depth to ensure compliance with safety regulations. This minimum requirement helps to promote overall road safety and vehicle reliability.
