Answer 1

The minimum tire tread depth permitted by federal DOT standards on all steer axle tires on trucks, tractors, or buses is 4/32 in.

Step-by-step explanation:

The minimum tire tread depth permitted by federal DOT standards on all steer axle tires on trucks, tractors, or buses is 4/32 in.

This means that the tire tread depth should be at least 4/32 of an inch.

Having sufficient tire tread depth is crucial for ensuring proper traction and grip on the road, especially in wet or snowy conditions.
