specifications established by these regulatory
agencies.
Alternative fuels, including biodiesel, that are not
substantially similar to the required test fuels
may adversely affect
compliance. As a result, Volvo does not warrant
the engine will conform to applicable Federal or
California emissions limits when operated on
biodiesel or other alternative fuels that are not
substantially similar to specified test fuels used
for certification.
Additional maintenance is required and is
covered in the maintenance manual "Fuel

WHEELS AND TIRES

Alcoa aluminum forged wheels ........... 9" X 22½"
Tires ...................... 315/80 R22.5 load range "L"
RECOMMENDED
PRESSURE AT MAXIMUM COLD LOAD
The recommended tire inflation pressures are
given in the applicable documents supplied with
the vehicle. In addition, minimum cold tire
inflation pressures are listed on the Department
of Transport (DOT) certification plate, affixed on
the left wall near the driver's seat.
Vehicle equipped with TPMS: The TPMS target
pressures are factory set to equal the prevailing
tire pressure at delivery time. When tire
pressures are increased to account for higher
vehicle weight, the TPMS set point need to be
increased accordingly.
CAUTION
These tire pressures are established in
accordance with the maximum allowable load
on each axle. A
recommended if the axle load is less than the
above specifications. Weigh vehicle fully
loaded and pressurize according to tire
manufacturer's recommendations. For non
standard tire and wheel specifications, see
Prevost tire pressure tabulation in "Coach
Final Record".
