Checking for worn tires
We recommend assessing your tires’ wear and tear once a month. Here’s how:
Narrow bands may appear in the grooves across the tire’s tread, shown in the picture. When these wear bars are even with the tread depth, meaning only 2/32” of tread remains, replace the tire. If tread is worn below 2/32 of an inch, water can’t be channeled away from the tread, which can cause hydroplaning at high speeds. Snow traction is also reduced.
Place a penny in the most shallow tread groove with Lincoln’s head down. If you can see the top of his head, the tire should be replaced.
