What is a wheel PCD?

PCD (Pitch Circle Diameter) is a measurement that can be used to find the right size for new steel or alloy wheels. Alloy wheels look nicer and are lighter than steel, but it's important to make sure the PCD of the wheel matches that of your car. The offset measurement of a wheel and hub also need to be taken into account when making any conversion.

PCD (Pitch Circle Diameter) and offset are the two most important things to know when you want to put new wheels on your car. PCD is the measurement of the hole in the middle of the wheel, and offset is how far the wheel is from where it attaches to your car.

Now PCD wheels are becoming more and more popular. The PCD wheel is a kind of wheel which has many small holes on the outer edge so as to reduce the weight of the wheel and increase its performance. PCDwheel is a brand new design, involving cutting out a large number of PCD from metal alloy plate under high pressure with PCD tools. The PCD wheel size can be adjusted within 1 mm, showing good dimensional accuracy.

The PCD is the diameter of the circle that goes through the center of all the wheel bolts or bolt holes. This is important to know because it helps you know how wide the wheel is. The PCD is usually measured in millimeters and it tells you how many bolts/bolt holes there are. For example, 5x100 means that there are 5 bolts spaced evenly on a 100mm bolt circle.

PCD process help us to produce huge lot of different wheels at one time, which not only save cost but also improve productivity

By the 1970s, the manufacturing industry had been revolutionized by automation equipment such as NC machines. In order to meet diversified market needs, BMW began developing products that could be mass-produced, such as PCD wheels. The PCD wheel is a kind of wheel which has many small holes on the outer edge so as to reduce the weight of the wheel and increase its performance.

PCD is the measurement you need to know if you want to change your car's tires or fit alloy wheels. PCD is short for Pitch Circle Diameter. To measure PCD, you'll need to be able to lift up a car and remove the tire and wheel. This can be dangerous if you're not trained properly. If you're not sure, ask a professional to do it for you. Once you have PCD measurements for your car, it will be easier to find new alloy wheels that fit perfectly. You can find out PCD of your wheel.

The easiest way to calculate the PCD is as follows:

1. Identify the size of the rim or tyre size. (This helps to narrow down the likely PCD sizes)
2. Measure the distance ‘S’ between two adjacent studs from the center of each hole.
3. Using the calculator enter the number of studs/holes & ‘S’ and press ‘calculate’.
4. Using the relevant diagram depending on the number of studs you have you should be able to identify the correct PCD.
