Volvo XC90: Wheels and tires / Recommended tire pressure
The tire pressure placard on the driver's side B pillar (between the front
and the rear door) indicates tire pressure for different loads and speed conditions.

Location of the tire pressure placard
The decal specifies the designation for the factory- mounted tires on the vehicle,
as well as load limits and inflation pressures.
NOTE
The decals shown in the Owner's Manual do not claim to be exact reproductions
of those found in the vehicle. The purpose is to show approximately how they look
and about where they are located on the vehicle. The information that applies for
your vehicle in particular is found on the decal on the vehicle.
Tire pressure decreases over time, which is normal. The tire pressure must
therefore be adjusted to maintain the recommended tire pressure.
Use the recommended inflation pressure for cold tires to help maintain good tire
performance and even wear...
(Option/accessory.)
The tire inflation pressure monitoring system6 provides an indicator symbol
in the instrument panel if pressure is too low in one or more tires...
