How To Know When You Need A Tire Replacement

One telling factor that you need to be aware of to determine the condition of your tires is tread depth (a vertical measurement from the top to the bottom of the tire's deepest grooves). With good treads, your car will be able to get better traction on the road. When tire treads have declined, your vehicle may struggle to drive in wet weather conditions. Worn treads can also make other parts of your vehicle wear down quicker. The state of Michigan suggests that you replace tires when they've worn down to 4/32 inch, as it is considered illegal to drive with your front tires lower than 4/32 inch and rear tires below 2/32 inch. Otherwise, the insufficient tread is deemed to be illegal and may land you a ticket.

 

Measuring Tread with Spare Change

If you don't have access to a tread depth gauge to measure your tread, do not fret! Did you know that tire tread depth can be checked with a U.S. penny (2/32 inch) or quarter (~4/32 inch)? 

  1. Insert the coin into the groove between two ribs with Lincoln's or Washington's head facing down.
  2. If the top of the head of the coin figure is covered, your tires have sufficient tread.
  3. If you can see Lincoln's or Washington's entire head, your tires have worn to less than 2/32 inch (penny) or less than 4/32 (quarter); and it is time for new tires!
