Tire Glossary
Tire terms you can see on this page

The size of the hole in the center of a wheel is known as the center bore or centerbore.

- Recommended for winter
- Run-flat tires
- Link comes to the calculator page for comparison
- Steel wheels
OE - Original Equipment
- Tire Pressure
- Front axle
- Rear axle

Offset is the distance in millimetres from the centre line of the wheel to the wheel’s mounting face. Given that the mounting face can be either in front of or behind the centreline, the offset can be either neutral, positive or negative.

Wheel backspace is the distance from a wheel's mounting surface to the back edge of the wheel.

The Pitch Circle Diameter (PCD) is the diameter of the circle which passes through the centre of all the studs, wheel bolts or wheel rim holes

hp - Mechanical horsepower
kW - Kilowatts
PS - Metric horsepower

Tire pressure is a vehicle's recommended cold tire inflation pressure. It is measured in bars or PSI (pounds per square inch).

A sales region is a global automotive region in which a vehicle was officially sold or is still being sold.

Ex.: 7J x 15 Rim width (inches) x rim diameter (inches)

ISO standard Ex.: M12 x 1.25 Nominal diameter (mm) x pitch (mm)

UN-series Ex.: 9/16" - 18 UNF Thread size (in) - thread pitch
UNF - Unified National Fine Thread

Example: 215/55 R16 91 T

215 is the tire width in mm
55 is the ratio of profile height to width or simply 'profile'. With the same width, the larger this indicator, the higher the tire will be and vice versa
16 - diameter of the wheel (disk) in inches. (It is the diameter, not the radius!). This is the inner size of the tire or the outer size of the rim
91 - load index. This is the level of maximum permissible load on one wheel
T - tire speed index

The method of attaching a wheel to a hub: wheel nuts or wheel bolts

The torque value specified by the manufacturer for wheel bolts or wheel nuts, which is to be set when tightening on the torque tool (torque setting). A rotational force given in Newton metres (Nm) or foot-pounds (ft-lbs), wheel torque measures lug nut / bolts tightness

The tires included with a new vehicle when it is purchased. OE tires are specifically chosen by the vehicle manufacturer to make the most of the vehicle's performance characteristics.
