# How do I know the PCD of my wheels?

## How do I know the PCD of my wheels?

The easiest way to calculate the PCD is as follows:

1. Identify the size of the rim or tyre size.
2. Measure the distance ‘S’ between two adjacent studs from the centre of each hole.
3. Using the relevant diagram depending on the number of studs you have you should be able to identify the correct PCD.

How are 5 bolt wheels measured?

If your wheel has a 5-bolt pattern, measure from the BACK of one bolt hole to the center of the second bolt hole as shown in the diagram. You can also measure from the CENTER of one bolt hole to the CENTER of the third hole using a multiplier of 1.05 to find your bolt circle.

### What is the most common 5 lug bolt pattern?

The most common 5 bolt pattern is 5 on 4-1/2. However, 5 bolt patterns also come 5 on 4-3/4, 5 on 5, and 5 on 5-1/2. It is important to know the bolt pattern before you buy new wheels to ensure a proper fit.

How do you calculate stud patterns?

Measure from the middle of one stud to the outside of the second stud (skipping a stud). The number you see will be the actual measurement of the bolt pattern. So if you see 4 1/2 inches, you have a 5 on 4 1/2 ( also 5×4.5 and 5×114.3) bolt pattern. Other common bolt patterns are 5×4.75 and 5×5.

#### What does PCD 100 mean?

100 is the simplest. So lets say you have an alloy with 4×100 PCD. It means it has four holes and the distance between one bolt hole and the one opposite to it is 100 mm. It simple means the circumference on which all 5 holes are drilled, it has a diameter of 114 mm. Same way 6 bolt wheel PCD is measured.

Are all 4 stud wheels the same?

Not all 4 stud wheels are the same Pitch Circle Diameter (PCD) although a 100 PCD is most common. Use this wheel suppliers site and key in each of the two cars and you’ll that Acura wheels should mount on the Rio.

## What is a 5×5 5 bolt pattern?

The 5×5. 5 Bolt Pattern or Pitch Circle Diameter (PCD) is made up of the stud count (5) and the bolt circle measurement (5.5), the notional circle determined by the center position of the studs.

How do you measure a 6 lug pattern?

6-bolt Patterns are measured in a straight line from center to center of two bolt holes sitting directly across from each other. 8-bolt Patterns are measured in a straight line from center to center of two bolt holes sitting directly across from each other.

### Will a 5×5 5 fit a 5×5 bolt pattern?

And yes you can put 5×5. 5 on a JK, either with adapters or by changing the axles (what I am going to do). But now I can get my 5×5 wheels and just have axles made with the 5×5 bolt pattern and not have to worry about strength.

What is the difference between PCD 100 and PCD 114?

So lets say you have an alloy with 4×100 PCD. It means it has four holes and the distance between one bolt hole and the one opposite to it is 100 mm. 5×114 is slightly different. It simple means the circumference on which all 5 holes are drilled, it has a diameter of 114 mm.

#### What does PCD 114.3 mean?

Pitch Circle Diameter
PCD (Pitch Circle Diameter) is the measurement of the diameter of the imaginary circle drawn through all of the wheel bolts or studs on a wheel. A ‘pcd’ of 4/114.3 means the wheel is four stud with a pitch circle diameter of 114.3mm.

Can you put 4 stud alloys on a 5 stud car?

For example, if your vehicle has four wheel studs or bolts but the wheels you want are manufactured exclusively for five-stud vehicles, you can buy a hub/PCD adapter that can change your fitment to a five-stud and allow you to fit your new alloys.

## Where is the PCD on a 4 stud wheel?

As shown on the diagram above it is easy to find the PCD on a 4 stud wheel. Just measure from the centre of one stud to the centre the opposite stud. This will work for any even number of studs. Please note there are two PCDs that are very similar.

What does PCD stand for on wheel nuts?

PCD stands for Pitch Circle Diameter. It is the diameter of a circle that is used to set the wheel nuts on. As shown on the diagram above it is easy to find the PCD on a 4 stud wheel. Just measure from the centre of one stud to the centre the opposite stud. This will work for any even number of studs.

### How big is a 5 stud trailer PCD?

5 Stud PCD’s. 5 x 6.5″ (165.1mm) is a very popular PCD as it will accommodate any trailer weight and more with a large diameter stud either 16mm or 5/8inch (15.875mm). It is used by Ifor williams and many other trailer manufacturers. We try and use it on all wheels and suspension 1500kg and above.

How do you measure the PCD of an alloy wheel?

However, the method we recommend is extremely simple but accurate, and we recommend it to all of our customers who want to measure the PCD of a wheel. Here’s how it works: • With a measuring tape or a set of Vernier calipers, measure from the outside of one wheel bolt to the same side of the next bolt hole.
