Vocabulary for understanding an Alloy Wheel

After Market Alloy Wheel or Mag wheel as they are known in the market are one of the most popular accessories and can be found on many cars in the market. What urged people to buy these wheels is the beautiful design which makes the car stands out from the rest. But before buying these wheels, there are some terms that the buyer needs to know to be able to communicate with the seller properly. Some of the most popular terms are:

  1. Wheel Rims: Wheel rims are measure in inches and it is used to measure the size of the wheel, for example a size 15” wheel or 17” wheel. Usually, to change to the aftermarket alloy wheel, people can change the size of the wheel by maximum of 2-3 inches in order to maintain that smooth drive.

2. Wheel Width: Width of the alloy wheel at the location where the tires are mount.  The width is measure from the edge of the front rim to the edge of the back rim. Those who wish to increase the size of the tire should also change the size of the wheel to match it.

3. P.C.D: PCD or “Pitch Circle Diameter” measure the diameter of the circle which passes through the center of the bolt hole. PCD value usually comes with the number of studs/hole for the wheel. For example, Isuzu D-MAX has 6x139.7 PCD, this means that it has 6 studs/hole and the diameter of the circle that passes through the center of this hole is 139.7 mm.

4. Offset: Offset is the distance between the “Hub Mounting Surface” and the center of the wheels (using the wheel width to measure). The Offset is measure in MM and its value determined the positioning of the wheel. A high (positive) offset value makes the wheel look more flat and without lip while a low to negative offset makes the wheel look more concave or have a deeper looking lip.

After knowing the above terms, we are sure that it will help you in the process of decision making when it comes to choosing a new wheel.
