How to read sidewall tire numbers and markings

The sidewall of your tires is filled with important information that tells you everything you need to know about your tire. The numbers can be a bit overwhelming to the untrained eye, so the best way to understand tire markings is to take an example and break it down, bit by bit. Below are tips and information to help you learn how to read tire size and other tire markings commonly seen in the U.S.

Centre Bore

Centre Bore

The centre bore is the size of the hole in the centre of the wheel where the spigot fits through.  The centre bore, (also known as spigot size), is the diameter of this hole, usually measured in millimetres.

Bolt Pattern/Pitch Circle Diameter (PCD)

Bolt Pattern/Pitch Circle Diameter (PCD)

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.  It is also known as the 'bolt circle'.

Offset

Offset

The offset of a vehicle's wheel is the distance between the centerline of the wheel and the plane of the hub-mounting surface of the wheel. It can thus be either positive or negative, and is typically measured in millimeters. Offset has a significant effect on many elements of a vehicle's suspension, including suspension geometry, clearance between the tire and suspension elements, the scrub radius of the steering system, and visually, the width of the wheel faces relative to the car's bodywork.
