Hello, my name is Mark Blocker. In this segment, we're going to cover how to check tire wear. To check tire wear, there's several things that we're going to want to look at. We're going to want to look at the outside, of the wear on the tire, and that's going to indicate whether we have a suspension problem, or maybe we're just, if you've got a worn down outside edge, that can be caused by an abusive driving habit, hard cornering, stuff of that nature, or if you've got one worn down on the inside, this could indicate that you've got something worn in your front suspension, or maybe a toe-out problem, where the tires are cocked toe-out outward, causing the inside to wear prematurely, but either way, we're going to want to look at both of the outsides of the tire, and that's going to give us indications of premature wear on the outside, which could indicate suspension problems, and stuff of that nature, and then overall tire wear down the middle. Now, you've got excessive tire wear down the center of the tire, this could be a over inflation problem, where you're running too much air pressure, or something of that nature, and then to check for the overall wear, to determine whether your tires have exceeded their overall wear limit, a good rule of thumb, is if you take a penny, and turn it upside down, so the head of the President sticks into the tire groove, and then you want to look at that President's head. If you can see the top of his head, then you don't have very much tread wear left on the tire itself, and it needs to be replaced, but as you can see in this case, you can't see the top of the President's head, so there's still good tire wear left on this tire. There's just a few examples of how you can check the tread wear on a tire.
