Always check for visable damage to the tire itself. If there is no visible damage, the easiest way to check tire wear is the penny test. Place a penny "head down" into the groove of a tire, If you can see the top of it's head, your tires need replace, legally. However, you should replace your tire when the tread is reduced below 4/32 of a inch. The easiest way to measure this is actually to us the "Quarter test". Do this test the same as the penny test on with a quarter, for a more accurate reading or check your tires "wear bars" which are bars within your tread that are below the tread and are the minimum safe depth for your tire.
