What is the minimum tread depth required in every major groove of a front tire?

The minimum tread depth required in every major groove of a front tire is 4/32 of an inch. This standard is critical for ensuring adequate traction, handling, and overall safety of the vehicle. Tires with less tread depth can significantly increase the risk of hydroplaning on wet surfaces and can reduce braking effectiveness. By maintaining a tread depth of at least 4/32 of an inch, drivers can help ensure that their vehicles have sufficient grip on the road, especially during adverse weather conditions. This depth is particularly important for front tires, as they bear the brunt of steering and handling forces. Keeping tires within this minimum depth helps promote better performance and safety on the road.
