A tire wearing on the outside edge can be a sign that the wheels are not aligned. Misalignment (camber and toe-in) can reduce the life of your tires, so be sure to routinely inspect for uneven tread wear. Wheel alignment can be checked by simply looking at the wear pattern on tires or by a trained technician with the use of an alignment rack. Always make sure the tires have plenty of tread (4/32” of an inch minimum) so you don’t lose traction.
An easy way to check your tread depth is to insert a penny in the tread groove or look at the wear bars (a raised molding inside the groove). If you can see all of Abe’s head or the bars are even with the top of the tread, the tires need to be replaced.
