Glossary of tire terminology
• Tire information placard: A placard
showing the OE (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 manufacturer.
• 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.
• 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.
• kPa: Kilopascal, a metric unit of air pressure.
• PSI: Pounds per square inch, a standard
unit of air pressure.
• 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.
• 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.
• 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.
• Cold tires: The tires are considered to be
cold when they have the same temperature
as the surrounding (ambient) air. This temperature
is normally reached after the vehicle
has been parked for at least 3 hours.
