What is the minimum tire tread depth for patrol tires?

• A. At least 4/32 inch
• B. At least 2/32 inch
• C. At least 6/32 inch
• D. At least 1/32 inch

Answer: (B)

Tread depth directly affects how well a tire can grip the road, especially in wet or slick conditions. As tread wears down, water and debris have fewer channels to escape, which increases the risk of hydroplaning and extended stopping distances. For patrol tires, the minimum permissible depth is two thirty-seconds of an inch. This depth marks the point at which the tire still has enough tread to evacuate water and provide some grip, while anything shallower would be unsafe and often illegal to use. The other options either imply more tread than the minimum or less than what is considered legally safe, so the lowest acceptable depth you should rely on for patrol tires is two thirty-seconds of an inch. To verify, use a tread depth gauge or a reliable gauge to check periodically and replace tires before they fall below this threshold.
