What is the minimum tire tread depth before rejection?

The minimum tire tread depth before rejection is established to ensure adequate traction and safety on the road. A depth of 2/32 inch is the threshold; any tire with a tread depth less than this is considered unsafe for operation. This minimum depth helps maintain necessary grip, especially in wet or slippery conditions, reducing the risk of hydroplaning and improving braking performance.

Tires must provide sufficient tread to channel water away and maintain contact with the road surface. When the tread wears down to 2/32 inch or less, the tire's ability to perform in adverse conditions diminishes significantly, posing a safety risk for both the driver and others on the road. It's critical for vehicle inspections to adhere to this standard as part of the overall commitment to road safety and vehicle performance.
