Review And Compare Tires Before You Buy
Penny Tire Test – Video
U.S. coins can be substituted for a tire tread depth gauge as tires wear to the critical final few 32nds of an inch of their remaining tread depth.
Place 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.
