You may have noticed recently that your car is in need of new tires. Perhaps you feel that you need a different style of tire, or maybe you did the "penny" test and realized that your tread was worn down. You want to buy new tires, but aren't sure what to get. While a reputable dealer should be able to guide you to the right tires, it doesn't hurt to know a little bit about what you might need. The code written on your tire wall can help you find a tire that is the right size and style for your car. Whether you are shopping locally, or buying your car tires online, make sure you know these important specifications.
Determining the type of car is pretty easy. If you have a passenger car, then you will want passenger tires. Trucks and sport utility vehicles, while usually sold with passenger tires, tend to do better with light truck tires, especially if those vehicles commonly carry heavier loads.
Several other numbers indicated on your car tire will tell you the sizing for your vehicle, such as the width of the tire across the tread, aspect ratio of the sidewall (compared to the width) and diameter of the rim. These numbers are important, because the wrong size wheel can put too much pressure on your whole assembly, potentially damaging brakes, struts, and axles.
