Proper tire maintenance can lead to improved vehicle handling, avoidable breakdowns, better fuel economy and a longer life for your tires. However, there are multiple factors to take into account when determining whether tires need to be replaced. Here is a short list of you can do easily to check the life of your tires. If you have any question about the health of the tire(s), always check with a professional.
The penny test is probably the most well-known way to determine whether or not you should replace your tires. Over time, your tire tread wears down. Using a penny, hold it with Lincoln’s head down between the tread. If you can see the top of his head, it’s time to replace those tires. At this point, the tires are no longer safe.
The quarter test is done the same as the penny test, but with Washington’s head down. The difference is that if you can see the top of Washington’s face, it’s showing the depth of 4/32” of an inch or more. 4/32” is the amount of tread you’d like to have for winter or adverse weather conditions. Independent tests have shown that tires perform better at this tread depth.
When you purchase a new set of tires, you typically have about six years with normal (up to 10,000 miles per year) use. After six years, you should replace your tires as a safety precaution. Tires can last up to ten years and even appear to be in good condition, however, there could be condition issues not visible. Often times, you will start to see cracks in the sidewall of the tires.
