06 Maintenance and specifications Wheels and tires • 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. 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: numbers are shown on the Federal/Canadian Motor Vehicle Safety Standards (FMVSS/ CMVSS) label. The total load on each axle must never exceed its maximum permissible weight. • 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. Gross vehicle weight (GVW) The vehicle's curb weight + cargo + passengers. • 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 vehicle, 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. NOTE • • Curb weight The weight of the vehicle including a full tank of fuel and all standard equipment. It does not include passengers, cargo, or optional equipment. The location of the various labels in your vehicle can be found on page 266. A table listing important weight limits for your vehicle can be found on page 271. Capacity weight All weight added to the curb weight, including cargo and optional equipment. When towing, trailer hitch tongue load is also part of cargo weight. Steps for Determining Correct Load Limit 1. Locate the statement "the combined weight of occupants and cargo should never exceed XXX pounds" on your vehicle's placard. 2. Determine the combined weight of the driver and passengers that will be riding in your vehicle. 3. Subtract the combined weight of the driver and passengers from XXX kilograms or XXX pounds. 06 • 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. NOTE For trailer towing information, please refer to the section "Towing a trailer", see page 210. Permissible axle weight The maximum allowable weight that can be carried by a single axle (front or rear). These 251
