2006 Volvo V50
[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
Rim: The metal support (wheel) for a tire or a tire and tube assembly upon which the tire beads are
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 inflation pressure is affected by the
number of occupants in the car, the amount of cargo, and the speed at which the vehicle will be driven
for a prolonged period. This information can be found on the tire inflation placard(s) located on the
driver's side B-pillar or on the inside of the fuel filler door on Canadian models, 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 car has been parked for at least
pg. 135 Vehicle loading
Properly loading your vehicle will provide maximum return of vehicle design performance.
Before loading your vehicle, familiarize yourself with the following terms for determining your vehicle's
weight ratings, with or without a trailer, from the vehicle's Federal/Canadian Motor Vehicle Safety
Standards (FMVSS/CMVSS) label, and the vehicle's tire information placard:
The weight of the vehicle including a full tank of fuel and all standard equipment. It does not include
passengers, cargo, or optional equipment.
All weight added to the curb weight, including cargo and optional equipment. When towing, trailer hitch
tongue load is also part of cargo weight.
