If you are a proud owner of a set of quality Goodyear tires, you should know that they won't actually last forever and that you will need to know when to replace them. Though most tires will generally survive somewhere between 20,000 and 60,000 miles, even the greatest set will eventually have to be replaced and it is crucial that car owners know when to do so.
First of all, despite your best efforts a tire may need to be replaced well ahead of schedule. The more you take long trips or drive over rough terrain, like speed bumps or gravel, the more you are reducing the life of each tire. One way of determining that a tire change is approaching is by how rough your car rides on even the smoothest roads. If your car starts to noticeably shake or starts to handle poorly, you should have a good look at each tire to ensure they are not the cause of the problem.
You always need to keep an eye on your tire tread to verify that it has not become too thin. After the tread for your tire begins to decrease, it is generally advised that you replace your tires with new ones. There are tread gauges for sale at your local auto parts store, but a lot of people just use an upside down penny, which is inserted one of the grooves between treads. If utilizing the upside down penny trick, when all of Lincoln's head is visible, it is time for you to change out that tire.
Finally, be sure to visually inspect your vehicle's tires on a regular basis and before any long journey. Take time out to make certain they are neither under or overinflated and thoroughly inspect for any sort of knick, hole, gash, or other damage. If you see a significant difference in tire pressure or notice any damage whatsoever, you should have the tire looked at by a professional.
When it finally comes time to change out your Goodyear tires, you will do well to replace the entire set at the same time. Not everyone has the money to do this, which is okay, but it is still greatly recommended that you at least change out the tire that shares an axle with the one that is no longer any good. Only replacing the worn out tire can make matters more critical for the others, as well as your vehicle's handling.
