Tires play a large part in your vehicle's overall health. Tires have an impact on your car's safety, smoothness of ride and fuel efficiency, which is why it is very important to keep your tires in good shape and replace them quickly when they are no longer usable. Take a look at some of the things that tires do for you, and learn more about how to know when it is time for new tires.
Tire Inflation Effects Gas Mileage
Properly inflated tires can increase your vehicle's fuel efficiency up to 3.3 percent. For every psi below the proper inflation, fuel efficiency decreases 0.3 percent because of extra friction on the tires. Properly inflated tires last longer and are safer. The proper air pressure can be found on a sticker in the door jamb of the driver's side door, and you can check the pressure with a tire gauge. Over inflated tires are not safe, and will not help with gas mileage.
Reading Tire Treads
Tire treads are designed to improve traction and divert water to prevent hydroplaning. If the tread is in bad condition, then it is time to get the tire replaced. Check your treads for tread wear bars that will appear as the tread wears down. All tires are designed with these tread wear bars so that owners can know when it is time to replace them. If you see that these bars have come even with the tire tread, then you know it is time to replace the tire.
Another trick you can use to check the health of your tire's tread using a penny. Place a penny inside the tire's tread. If you can see all of President Lincoln's head, then you know it is time for new tires.
How Often Should I Replace My Tires?
The NHTSA places the maximum lifespan of a tire at ten years. After five years of use, you should have your tires checked at least once a year by a professional. But you should always keep an eye on your tires' conditions, and pay attention to how the tires feel on the road. A rough ride or unusual vibrations can be a sign that a tire is damaged. If you have any doubts about your tires, it is better to be safe and have them repaired or replaced.
