With so many different types, styles, sizes, and prices of tires out there it is hard to know the right kind of tires for your vehicle. Knowing your environment, and the primary environment that you will be driving in, is the first step to choosing the right tires for your vehicle. If you live in an area that has nice, long winters it is probably best to get all weather tires or winter tires. If weather is not an issue, do not forget to consider the terrain. Tires are made differently for city driving and off roading. Once you have established the type of tires you need, the next step is the size. Knowing the right size tires for your car is very important when you buy tires. Every make, model, and year may be different so it is important to find out what size best fits your specific vehicle. If you don't already know the size of your tires, there are two ways that you can find out. The first way is by looking at your tires sidewall. There you will find three sets of numbers that give your tires width, height and width ratio, and rim diameter. If you are unable to locate this information on your tires, you can consult your vehicles owner manual. There you will find this information as well as information on the load capacity and speed rating. This information is particularly important if you are looking to upgrade the size of your tires. If you are still uncertain of the size you can contact the dealership or many online tire sites that can walk you step-by-step through the tire buying process. Once you have all the information you need, you are free to buy new tires. Once you have the right type and size you are all set to have years of safe and happy driving.
