Wheels are among the most vital parts in the car. They are the ones that keep it moving and thus, they are indispensable in a vehicle. The size and the quality of the wheels significantly affect your ride quality and handling so always make sure they are in perfect shape and condition. Taking care of them is a must so as not to sacrifice your vehicle's performance. They also need special attention since they are closest to the road; hence, they are exposed to a lot of corrosion-causing elements.

Aside from contributing to ride quality and handling abilities, the wheels can also make the car look better and a lot sportier. People have always been concerned with how their vehicles should look and thus they replace or customize some of the parts to make it different from the rest on the road. The wheels are among those that are often replaced to achieve their desired appearance. Accessories are also added to the wheels, such as the hub caps and wheel covers. These auto accessories are designed to match the user's various driving needs and moods.

In buying replacement wheels for your car, there are important things you need to know, especially if you are new to driving. You cannot just choose any kind of wheel in lieu of the original wheel of your car. There are different wheel specifications for every kind of vehicle and car model since suspension design varies from one vehicle to another. Take note that the wheels work hand in hand with the suspension system whose job is to keep the tires in tight contact with the road as the vehicle turns, brakes or is driven down the road without sacrificing comfort of the passengers.

Three aspects of the wheels are relevant to the suspension design: wheel offset, aspect ratio, and tire width. All these should be considered in choosing the best replacement wheels for your vehicle.

Offset refers to the distance from the very center of the wheel to the mounting surface of the wheel disc at the hub. Wheel offset can be positive, negative or zero. A "0" offset means that the mounting surface of the wheel is in the center of the wheel. This measurement is very important in positioning the tire. This also provides for adequate dual spacing.

Aspect ratio is the ratio between the width of the tire and the height of its side wall. A tire specified as "205/60/15" for example, has a width of 205mm and 60% aspect ratio. The 15" refers to the size of the wheel to which it is fitted. You shouldn't buy wheels or tires with lower aspect ratio than what is required because this will wear them out easily as ride quality will deteriorate. However, this could also result to more precision in turning.

You might be thinking of getting wider wheels to give your car a racing car look. Better think about this again. While is it true that wider wheels and tires can give your car a chunk of gutsy looks, they can also ruin your driving satisfaction. This is because the weight of the vehicle would not be evenly spread over the wheel and tire width. Resistance is also increased, thus you wheels and tires could wear out fast.
