What is the minimum tread depth for the steer-tire?

• A. 2/32 inch
• B. 8/32 inch
• C. 4/32 inch
• D. 6/32 inch

Answer: (C)

Steering tires must maintain enough rubber to keep precise control and resist hydroplaning, so the minimum allowed tread depth on the steer axle is 4/32 inch. This depth helps ensure good grip in wet conditions and stable handling. Measure with a tread depth gauge or ruler across several grooves around the tire; if any groove is shallower than 4/32 inch, the tire should be replaced. The 2/32 inch minimum applies to other tires, not the steer, while 6/32 or 8/32 inch would be more than the required minimum and are not the standard legal threshold for steer tires.
