You may have learned a few car maintenance basics while you were learning how to drive. To check the tread on your tires, use a penny.
The cost of this simple test has gone up over the years. Many automotive experts recommend using a quarter for this check instead of using a penny. Tony Markovich explains how to do this in an article for TheDrive. Here is what to know.
What is the significance of tire tread?
Markokvich says that the tire tread is cut in a pattern of grooves and ridges. The tread is important because it is how a vehicle grips the road.
If precipitation is involved, the grooves and ridges become less effective at allowing the vehicle to maintain traction. The treads help keep the car in control when the roads are slick.

Markovich said that the rule assumed that 4/32 of an inch was the safe limit. The quarter test is used when it comes to tire safety.
