Purpose
The Safe Tread Alliance exists to save lives by advancing tire safety standards in the United States. Current regulations allow tires to wear down to unsafe depths 2/32”, and in some states as low as 1/32”. These thresholds are outdated and deadly. Inspired by Europe’s R117-04 regulation, which balances safety, environmental responsibility, and consumer protection, STA leads the charge to establish a 4/32” minimum tread depth standard across the nation.
By advocating for smarter regulations, educating the public, and correcting misinformation such as the dangerous penny test, STA’s purpose is clear: to protect families, prevent tragedies, and ensure that every tire on America’s roads is truly road ready.
Mission Statement
The Safe Tread Alliance is committed to setting a new tread depth standard in the United States to replace outdated and unsafe thresholds. Current regulations allow tires to be worn down to 2/32” and in some states as low as 1/32” a dangerous minimum that costs lives every year.
Inspired by Europe’s proven R117-04 regulation, we advocate for a 4/32” minimum tread depth nationwide. This standard saves lives by reducing stopping distance, preventing hydroplaning, and improving overall road safety.
We are equally dedicated to correcting widespread misinformation such as the outdated messaging like the penny test that gives drivers a false sense of security. This misinformation is killing lives. By driving national awareness, advancing public education, and leading advocacy in the absence of stronger federal regulation, STA’s mission is clear: to protect families, prevent tragedies, and ensure that every tire on America’s roads is truly road ready.
