How do I find my PCD?

How do I find my PCD?

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.

What is a PCD electronics?

Pitch circle diameter, in mechanical drawing; See Wheel sizing. Proximity coupling device, a reader device for NFC Cards in ISO/IEC 14443.

What does PCD and offset mean?

PCD, offset, and centre spigot diameter. WHEEL OFFSET, PCD, & CENTRE SPIGOT DIAMETER. WHEEL OFFSET. Offset is the distance between the imaginary centreline of the wheel (as viewed from behind the wheel as it would roll away from you) and the inside face that bolts up against the wheel hub on the car.

Is PCD the same as offset?

Just because a wheel from one vehicle has the same PCD and offset as the wheel from another does not mean they are interchangeable – the centre bore of the wheel and hub must also be the same to ensure centralisation of the wheel, and the shape of the spokes must ensure clearance of the brake calipers.

Is ET positive or negative offset?

Most front wheel drive vehicles have positive ET wheels. Zero Offset wheels have their mounting face even with the center line of the wheel and are by definition “ET 0″. Negative Offset wheels have their mounting face toward the rear of the wheel – powerful rear-wheel drive cars often have wheels with negative offset.

How do you read wheel sizes?

The two-digit number after the slash mark in a tire size is the aspect ratio. For example, in a size P215/65 R15 tire, the 65 means that the height is equal to 65% of the tire’s width. The bigger the aspect ratio, the bigger the tire’s sidewall will be.

How do rim sizes work?

The first number, 4, indicates the number of lug holes in the wheel. The second number, 100, indicates the distance in millimeters from one hole to another, across the face of the wheel. It is common for the second number in a bolt pattern to either be displayed in inches or millimeters.

What does the 265 mean in tire size?

265. This number indicates that your tire has a width of 265 millimeters. 70. This number means that your tire has an aspect ratio of 70%. In other words, your tire’s sidewall height (from the edge of the rim to the tire’s tread) is 70% of the width.

What do the numbers mean on lawn mower tires?

Mower tires with the two-number system identify the tire’s width and diameter. In the three-number system, the first number before the X is the tire’s diameter when inflated and not loaded, the middle number is the tire’s width and the final number is the rim width.
