The condition of your tires is a significant factor in how well your car rides, and tires with insufficient tread can cause serious accidents, especially on wet roads. Luckily, you don't need to be a mechanic to keep tabs on the state of your tires.
The deeper the tread is on your tires, the more friction they have against the road. This is especially important when the road is wet. Friction is needed to stop properly, to maneuver around corners and curves, and to keep from hydroplaning.
The West Virginia State Code does not specify a minimum tire tread requirement.
At the end of 2007, West Virginia was one of six states that had no tread requirement. Forty-two states required tire tread to be at least 2/32-inch deep, while two specify just 1/32 inch.
Many tires have bars that run across their width, under the rubber. You can only see them once the tire has worn down to 2/32 of an inch. When they are visible, change your tires.
Stick a penny into the groove of your tire, with Lincoln's head going first. If you can see the top of his head, your tread is too low and you should replace your tires.
