07 Wheels and tires Glossary of tire terminology Terminology • B-pillar: The structural member at the side of the vehicle behind the front door. • Tire information placard: A placard showing the OE (Original Equipment) tire sizes, recommended inflation pressure, and the maximum weight the vehicle can carry. • Bead area of the tire: Area of the tire next to the rim. as the surrounding (ambient) air. This temperature is normally reached after the car has been parked for at least 3 hours. Properly loading your vehicle will provide maximum return of vehicle design performance. • Sidewall of the tire: Area between the bead area and the tread. • 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 manufacturer. • 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. • 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 35 psi [37 psi (2.5 bar) for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying capability. • Maximum load rating: a figure indicating the maximum load in pounds and kilograms that can be carried by the tire. This rating is established by the tire manufacturer. • Maximum permissible inflation pressure: the greatest amount of air pressure that should ever be put in the tire. This limit is set by the tire manufacturer. • Extra load: A class of P-metric or Metric tires designed to carry a heavier maximum load at 41 psi [43 psi (2.9 bar) for Metric tires]. Increasing the inflation pressure beyond this pressure will not increase the tires load carrying capability. • Recommended tire inflation pressure: inflation pressure, established by Volvo, which is based on the type of tires that are mounted on a vehicle at the factory. This information can be found on the tire inflation placard(s) located on the driver's side B-pillar and in the tire inflation table in this chapter. 07 • kPa: Kilopascal, a metric unit of air pressure. • PSI: Pounds per square inch, a standard unit of air pressure. • Cold tires: The tires are considered to be cold when they have the same temperature 184
