what is a good tread depth
Here in the U.S., tire tread is measured in 32nds of an inch. A brand-new tire has a tread depth around 10/32nds of an inch (approximately 1/3 of an inch). Some tires, like winter tires or off-road tires, may have a deeper tread. As you drive on the tires, the tread gradually wears down. If you reach the point where thereâs 2/32nds of an inch of tread or less left, the tires are bald and are considered legally worn out in most states.
