450 Wheels and tires
The tire pressure table shows the recommended
tire pressures for all tires approved for this vehi‐
cle. The recommended tire pressures apply for
cold tires under various operating conditions, i.e.
loading and/or speed of the vehicle.
If one or more tire sizes precede a tire pressure,
the tire pressure information following is only
valid for those tire sizes.
The load conditions "partially laden" and "fully
laden" are defined in the table for different num‐
bers of passengers and amounts of luggage. The
actual number of seats may differ from this.
Some tire pressure tables only show the rim
diameter instead of the complete tire size, e.g.
R18. The rim diameter is part of the tire size and
can be found on the tire side wall (
