Ah! The quarter test. The quarter test is ideal for those who are monitoring their tires’ tread depth. If you have had the tires for a while and are wondering if they are getting close to needing to be replaced.
You may be more familiar with the penny test. The penny test is used to determine if the tires need to be replaced right away.
When driving, only a tiny portion of each tire is in contact with the road, and that’s why experts say it’s so important that your tires be in good shape.
New car tires start with a tread depth of 10/32nds to 12/32nds. When you feel your tires are getting worn, I would recommend doing the quarter test.
The Quarter Test
The Penny Test
Insert a penny into the tread area with the head pointing down. If you can see all of Lincoln’s head, the tire(s) need to be replaced ASAP! The tread depth is at 3/32 to 2/32 inch. At this point, your tires are too worn out to be considered legal, or safe, and you could actually be issued a ticket if you were in a car accident and you were at fault.
