ST. LOUIS — Just when we were questioning the value of the American penny, we were reminded about its alternative value of a measuring stick. The old tire tread penny trick!
Before we review the particulars, it's important to note that for your safety, you should always consult tire professionals about tire safety, including tire wear. However, if you aren't too sure if you're tires are lacking in treadwear, Abe Lincoln can be of assistance.
According to the National Highway Traffic Safety Administration, tire tread provides the gripping action and traction that prevents your car or truck from slipping and sliding, especially in winter road conditions. Tires are not safe and should be replaced when the tread is worn down to 2/32 of an inch.
5 On Your Side stopped by Firestone to talk with Tim Liebig. At Firestone, they have a special tread gauge to tell your tire story, but Tim also shared the easiest way to check your tread without making a special trip to the tire shop: "So if you don't have time to go into a tire store, you can do the old Abe Lincoln … put your penny in a tread and see how your treads are lookin'."
A rule of thumb is the rule of the penny.
"Lincoln's head upside down to measure the tread," Leibig said. "If you see the head, then, it's time to get tires or start considering getting tires before the winter."
So, if you can see his entire head. your tires are worn to 2/32 of an inch or less. Those tires can be a serious safety risk. Their stopping distance and the traction they get are significantly decreased.
Make sure the car is in park before you check and try it out. Honest Abe won't lie about your tire safety.
