Q: How do I know when I need new tires? – Mr. Larrimore
A: Mr. Larrimore,
When your tread wears down to 4/32 of an inch you start to lose significant traction on wet or snowy roads. A Washington quarter, placed upside down in the tread grooves at several points is a handy gauge. You’re ok if the tread covers part of Washington’s head. To be legal in most states, tires must pass the Lincoln penny test, a minimum tread depth of 2/32 of an inch. Manufacturers also place wear bars in the grooves between tire treads. When the tread is nearly flush with the bars, it’s time to replace your tires.
