Safe Tread Alliance | Raising the Standard for Tire Safety in America

Outdated tire laws are putting drivers at risk every day. Safe Tread Alliance is a national coalition dedicated to modernizing tire safety standards, protecting families, and preventing preventable tragedies on America’s roads.

Why Tire Safety Matters in the United States

In the U.S., tires are legally allowed to remain on the road until tread depth reaches 2/32 of an inch — and in some states, as low as 1/32. At these depths, traction is compromised, stopping distances increase, and hydroplaning risk rises significantly.

HA Safer Tire Standard: The 4/32 Solution

Inspired by Europe’s R117-04 regulation, Safe Tread Alliance advocates for a 4/32-inch minimum tread depth standard nationwide to improve wet-weather traction, reduce stopping distance, and save lives.
