You can substitute a tire tread depth gauge with a U.S. coin to measure those critical few 32nds of an inch of remaining tread depth. When placing a penny into several tread grooves across the tire, if part of Lincoln's head is always covered by the tread, you have more than 2/32" of tread depth remaining.
We believe that snow capability is greatly diminished when your tire's tread depth dwindles to approximately 6/32" of remaining tread depth. The rule of thumb on measuring this amount of tire tread is to once again use a penny. If after placing the penny into several grooves across the tire the Lincoln Monument is always covered by the tread, you have enough remaining tread to handle snow-covered roads.
