Description
Tire tread depth measures the height of the rubber that contacts the road—typically in 32nds of an inch. New tires usually start with 10/32″ to 12/32″ of tread. Adequate tread depth is vital for traction, water dispersion, and overall safety, especially in wet or slippery conditions. As tread wears, grip and handling decrease, increasing the risk of hydroplaning and longer stopping distances. Checking tread depth regularly—using a gauge or the simple penny test—helps ensure tire safety. If the tread is below 2/32″, it’s time for replacement, as the tire is legally bald in many areas. Uneven wear can also indicate alignment or pressure issues. Tires with deeper treads offer longer life and better traction but may cause more road noise. Regular inspection and timely replacement of worn tires are key to maintaining vehicle safety, control, and performance on the road.
