Glossary of Tire Terminology

*Tire label: A label showing the original equipment tire sizes, recommended inflation pressure and the maximum weight the vehicle can carry.

*Tire Identification Number (TIN): A number on the sidewall of each tire providing information about the tire brand and manufacturing plant, tire size and date of manufacture. Also referred to as DOT code.

*Inflation pressure: A measure of the amount of air in a tire.

*Standard load: A class of P-metric or Metric tires designed to carry a maximum load at set pressure. For example: For P-metric tires 35 psi (2.4 bar) and for Metric tires 36 psi (2.5 bar). Increasing the inflation pressure beyond this pressure will not increase the tire’s load carrying capability.

*Extra load: A class of P-metric or Metric tires designed to carry a heavier maximum load at 42 psi (2.9 bar). Increasing the inflation pressure beyond this pressure will not increase the tire’s load carrying capability.

*kPa: Kilopascal, a metric unit of air pressure.

*PSI: Pounds per square inch, a standard unit of air pressure.

*Cold tire pressure: The tire pressure when the vehicle has been stationary and out of direct sunlight for an hour or more and prior to the vehicle being driven for 1 mi (1.6 km).

*Recommended inflation pressure: The cold inflation pressure found on the Safety Compliance Certification Label (affixed to either the door hinge pillar, door-latch post, or the door edge that meets the door-latch post, next to the driver's seating position), or Tire Label located on the B-Pillar or the edge of the driver door.

* B-pillar: The structural member at the side of the vehicle behind the front door.

*Bead area of the tire: Area of the tire next to the rim.

* Sidewall of the tire: Area between the bead area and the tread.

*Tread area of the tire: Area of the perimeter of the tire that contacts the road when mounted on the vehicle.

*Rim: The metal support (wheel) for a tire or a tire and tube assembly upon which the tire beads are seated.
