If you're like most of us, or maybe I should say if you're like me, the way you choose what new tires you should purchase for your car is by reading the label on the side of your existing car tires. After comparing the prices of the compatible tires with the amount of money in your tire budget, then a choice can be made. But is it the right choice? I mean, if you have no idea what the label on your tire means or what you are purchasing, you could really be leaving out a whole new world of tire.
