FAQ
Frequently Asked Questions About Tire Safety
What does 4/32 mean on a tire?
4/32 means the tire has four thirty-seconds of an inch of remaining tread depth. Tread depth affects braking, traction, and the ability to channel water away from the tire.How do I check my tire tread depth accurately?
Use a tread depth gauge to measure tread depth in multiple spots across the tire. Measuring in several grooves helps identify uneven wear.When should I replace my tires for better wet-weather safety?
For improved wet-weather braking and traction, many safety recommendations advise replacing tires around 4/32 of an inch, even if the legal minimum is lower.Do all states have the same tire tread depth laws?
Most states use a 2/32-inch legal minimum tread depth, but inspection requirements and enforcement vary by state.What is the 4/32 Initiative?
The 4/32 Initiative is an effort to modernize minimum tire tread depth standards to 4/32 of an inch to improve wet-weather performance and reduce hydroplaning-related risks.
The 4/32 Initiative is a data-backed effort to modernize tire safety standards and improve real-world driving safety.
