Maintenance Monday: Penny Tire Tread Test
When should your tires be changed? The penny test is a great way to check your tire tread and to make sure that your wheels are safe enough for the road. Place an upside-down penny in the grooves. As long as part of Abe Lincoln's head is covered, then the tread is high enough and your tires are fine.
- Place a penny between the tread ribs on your tire. A “rib” refers to the raised portion of tread that spans the circumference of your tire. Tire tread is composed of several ribs.
- Turn the penny so that Lincoln’s head points down into the tread.
- See if the top of his head disappears between the ribs. If it does, your tread is still above 2/32” , If you can see his entire head, it may be time to replace the tire because your tread is no longer deep enough.
Consistent wear around the whole tire is normal, but uneven tread wear could be a sign of improper inflation, wheel misalignment, or a variety of other things. If you see uneven tread wear, you should have a technician inspect your vehicle.
