Massachusetts Minimum Tire Depth

Massachusetts Minimum Tire Depth

In Massachusetts the minimum tire thread depth is 2/32 inches. Tires must have at least 2/32 inches of tread depth in the proper grooves and no fabric breaks or exposed cords. Tires should be tested in various locations and in between different treads around each tire.

​How to check your tire’s tread depth

Massachusetts Minimum Tire Depth

The best way to check tire depth is by using a tread depth gauge.  If you don’t have a gauge you can use a penny.  Place a penny into several tread grooves across the tire. If part of Lincoln's head is always covered by the tread, you have more than 2/32" of tread depth remaining.

​Will my tires pass inspection?

Tires are worn out when they have worn down to 2/32" of remaining tread depth. Your car will not pass a state inspection.
