What is the minimum tread depth required for tires to be street legal?

The minimum tread depth required for tires to be street legal is typically set at 2/32 of an inch, which is equivalent to 1/16 of an inch. This standard ensures that tires have sufficient tread to provide adequate traction, especially in wet or rainy conditions, thereby enhancing safety on the road. Tires that do not meet this minimum depth could lead to decreased performance, particularly on slippery surfaces, increasing the risk of hydroplaning and loss of vehicle control.

Having the correct tread depth is vital for effective handling, braking, and overall vehicle stability. This requirement is enforced to promote safe driving practices and to minimize the number of accidents caused by tire-related issues.
