Let's face it. Tires don’t last forever. And the two main reasons for replacement are wear and damage. There are several ways to inspect your tires. You can visually check their general condition and look for abnormal and uneven wear patterns. You could also perform the “penny test” or check to see if the “wear bars” are visible to ensure there is sufficient tread remaining to safely operate the vehicle. There are variables in how long your tires will last, including composition, driving habits, environment, inflation, and more. We recommend replacing your tires when the wear bars are visible, or there is less than 1/16 of an inch of tread remaining. The "penny trick" works because the distance between the rim and Lincoln's head is 1/16 of an inch -- the minimum required tread depth. When your tire tread is lower than 1/16 of an inch, your vehicle may not have the handling, or traction it needs for regular driving. Installing new tires can not only increase your car's fuel efficiency, but it can also improve your car, truck, or SUVs' handling, braking ability and ride quality. From a safety standpoint, tires are a critical safety feature. A driver's ability to control their vehicle depends on the traction between their tires and the road, and it could ultimately lead to an accident. From an environmental point of view, better gas mileage is always good for the environment.
