The differences surprised us! Vehicles equipped with the 2/32 minimum tire tread depth took about 100 more feet to stop and were still traveling at about 45 mph at the same distance the vehicles equipped with the 4/32 deep tires had already come to a complete stop!
But age is not the only factor. Tread matters too. A worn tire can be just as dangerous, or even more so, than one that is simply old. While the minimum safe tire tread depth is 2/32â³, consider replacing your tires at the 4/32â³ mark, especially if you drive in rainy and snowy conditions.
