Tread Lightly: Worn Tires Put Drivers at Risk

ORLANDO, Fla. (Jun. 7, 2018) – Afternoon downpours could spell disaster for millions of road trippers this summer, thanks to an unlikely suspect – tires. New research from AAA reveals that driving on relatively worn tires at highway speeds in wet conditions can increase average stopping distances by a staggering 43 percent, or an additional 87 feet — more than the length of a semi-trailer truck — when compared to new tires. With nearly 800,000 crashes occurring on wet roads each year, AAA urges drivers to check tread depth, replace tires proactively, and increase following distances significantly during rainy conditions.
“Tires are what keep a car connected to the road,” said John Nielsen, AAA’s managing director of Automotive Engineering and Repair. “Even the most advanced safety systems rely on a tire’s basic ability to maintain traction, and AAA’s testing shows that wear has a significant impact on how quickly a vehicle can come to a stop in wet conditions to avoid a crash.”
In partnership with the Automobile Club of Southern California’s Automotive Research Center, AAA conducted testing to understand performance differences at highway speeds between new all-season tires and those worn to a tread depth of 4/32” on wet pavement. AAA research found that:
