What is the minimum tread depth on all fleet vehicles?

The minimum tread depth for all fleet vehicles is set at 4/32 of an inch. This standard is established to ensure adequate traction and safe handling of the vehicle under various road conditions. Tires with sufficient tread depth are crucial for maintaining grip on wet or slippery surfaces, which directly affects the vehicle's braking distance and overall stability. If the tread depth falls below this minimum, the risk of hydroplaning increases, and the vehicle may not perform effectively in inclement weather.

Maintaining the minimum tread depth is also essential for maximizing the lifespan of the tires and promoting consistent vehicle performance in the field. Regular inspections should be conducted to monitor tread depth and ensure safety compliance within fleet operations. This practice aligns with safety standards in vehicle maintenance as well as operational responsibilities for driver/operators.
