The differences surprised us! Vehicles equipped with the 2/32 minimum tire tread depth took about 100 more feet to stop and were still traveling at about 45 mph at the same distance the vehicles equipped with the 4/32 deep tires had already come to a complete stop!
In the UK, 1.6mm across 75% of the width of the tread. There is no national law in the U.S. on tread depth. However 42 states consider 2/32 the minimum. California & Idaho coâ¦nsider 1/32 the minimum. Arkansas, Montana, New Mexico, North Dakota, South Carolina, and West Virginia have no minimum. A tire below 3/32 cannot pass the Texas safety inspection. In Canada the minimum is 2/32. Some experts including Consumer Reports consider 4/32 the minimum. My opinion is that when the tire has less than 3/32 it should be replaced.
