Checking tire tread depth is a straightforward and efficient means to make sure your tires are protected and authorized to drive on. It may be executed with a wide range of instruments, together with a penny.
To test your tire tread depth with a penny, merely insert the penny into the tread with Lincoln’s head going through down. If the highest of Lincoln’s head is roofed by the tread, your tires have not less than 2/32 of an inch of tread remaining, which is the authorized minimal in most states. If the highest of Lincoln’s head is seen, your tires must be changed.
