rubber plantations in Indonesia. Most people buy their tires from one of the
1,000 retail stores in the US.
Few people realize that it's really easy to buy goodyear tires online and save money in the process. Tirerack makes choosing the correct tire easy with their easy online tire selector. If you prefer Goodyear tires, you can select Goodyear tires in as you go throught the selection process.

Tirerack will give you the option to ship your choosen tires to one of the installers that they have listed. We have used this system and it works great. Once the installer gets your tires from Tirerack they call you and make an appointment. Balancing the replacing the tires and anything else require is covered by the installer.
To keep your tires running smoothly longer it's important to keep them properly inflated, rotated, and aligned. Be sure the tire installer checks your alignment or that your regular mechanic fixes your alignment just after you get new tires.
Goodyear tire has a good guide for tire maintenance. They cover how to check if your tire tread is too low, how to maintain proper inflation of the tires, the reason to balance tires, and more.
We found their description of different wear patterns on tires interesting. From looking at your tires you can see if they are over inflated, under inflated, not balanced, or misaligned. We think that understanding these simple rules will make people better consumers and avoid unscrupulous shops from taking advantage of you.
We knew that driving on a tire warms it. Consequently the measured tire pressure is higher after driving. We were surprised to learn from the article that only one mile of driving prior to measuring tire pressure will adversely affect the tire pressure measurement.
We also found the various patterns of wear particularly intersting. Over inflation results in the middle of the tire wearing more, and underinflating causes the edges of the tire to wear faster. That makes sense. We had no idea that improper balance was easy to tell from the tire wear pattern. Cupping, dipping, or scalloping signals poor tire balance, suspension, or steering issues. These wear patterns are most common on the front tires.
Another interesting wear pattern occurs due to misalignment when the tire edges get sawtooth edges. The tire may even get a feathered appearence. We find that it's hard to know for sure when a car's tires might be out of alignment. Only a few types of misalignment are noticeable from the car pulling to one side or the other. A simple check of tire wear can tell you quickly if the car should be aligned even if it doesn't pull. We'll be checking our tires today to see if any of those potholes or bumped curbs have caused problems with our tire allignment.
The article also says that underinflation of the tire is far worse for tire life than over inflating. We think that's an important thing to remember. Keep the tires properly inflated. Be sure to measure tire pressure on cold tires otherwise you might under inflate the tires.
The article also reports that badly balanced tires may cause driver fatigue due to the vibration of the car from the tire.
