When it's time for you to replace the tires on your car, which ones you buy at the store largely depend on which ones are right for you and your car. Manufacturers make tires to exactly fit specific models of cars. You need to make sure the tires you buy are the exact ones your car needs. There are many different types of construction for car tires. You can get the standard sizes, white wall or black wall, radial, diagonal, or belted bias tires.

You never want to get a tire for your car that is smaller than the tire your manufacturer provided for your car. This can cause damage to your car and cause the tires you buy to wear at an abnormally quick speed. In addition, you ideally want to buy all your tires at the same time, including the spare tire. This is so you can wear your tires evenly.

When determining the right tires for your car, you need to look at your car's tires for a series of numbers and letters that will tell you the exact size, type, and model of your tires. This code will also tell you the maximum inflation pressure allowed on the tire. This code is found on the sidewall of your car's tires. It's usually molded onto the tire by the manufacturer. Also on the tire, manufacturers list a safety warning on your tire, which says how underinflating, overinflating, or overloading your car tires can cause serious damage.

Radial tires are the traditional tires found on most cars. These tires have cords running across the tire from the points at which the tire touches the rim of the wheel. Radial tires rely on steel belts for strength. Belts are wound from steel filaments and run inside the circumference of the tire. Radial tires are generally used for vehicles not hauling heavy loads because they provide a lighter tire with less side support but with a high amount of durability for driving long distances.

Diagonal tires have two or more body piles, and they cross at a 35-degree angle to the center of the tread. These tires can offer better traction for vehicles traveling long distances.

Belted bias tires are similar to diagonal tires, except they have at least two belts under the tread. Belted bias tires use a variety of natural and synthetic rubbers with fabric reinforcements to strengthen the inner linings of the tires. Bias tires are used if you're going to be hauling heavy objects because traction, tread wear, and rolling resistance are not major issues with bias tires.
