Any tire on a steering axle of a power unit with less than ________ inch tread at any point on a major tread groove, is cause for failure of the inspection. Fill in the blank.

a) 5/32
b) 2/32
c) 1/8
d) 4/32

Answer 1

According to the FMCSA, any tire on a steering axle of a power unit with less than d) 4/32 inch tread at any point on a major tread groove is cause for failure of the inspection.

Step-by-step explanation:

According to the Federal Motor Carrier Safety Administration (FMCSA), any tire on a steering axle of a power unit with less than 4/32 inch tread at any point on a major tread groove, is cause for failure of the inspection. This means that the tire tread depth should be at least 4/32 of an inch to pass inspection.

Tread depth is an important factor for tire safety and grip on the road. It helps to maintain traction and channel water away from the tire surface, reducing the risk of hydroplaning. Insufficient tread depth can compromise the tire's ability to grip the road properly, especially in wet or slippery conditions.
