Tyre Pressure - Volvo XC90 Owner's Manual

Recommended tyre pressure
The tyre pressure label on the driver's side
door pillar shows which pressures the tyres
should have at different loads and speed con-
ditions.
Stated on the decal:
•
Tyre pressures for the car's recom-
mended tyre size
•
1
ECO pressure
•
Spare wheel tyre pressure (Temporary
Spare).
ECO pressure results in improved fuel economy.

Checking the tyre pressure
Check the tyre pressure regularly.
NOTE
Tyre pressure decreases over time, this is
a natural phenomenon. Tyre pressure also
varies depending on ambient temperature.
Even after several kilometres of driving, the
tyres warm up and the pressure increases. So
air must not be released if the pressure is
checked when the tyres are warm. While the
pressure must be increased if it is too low.
Inadequately inflated tyres increase fuel con-
sumption, shorten tyre lifespan and impair the
car's roadholding. Driving on tyres with tyre
pressure that is too low can also result in the
tyres overheating and disintegrating.
For information on the correct tyre pressure,
see page 298. The specified tyre pressures
refer to "cold tyres". ("Cold tyres" means the
tyres are the same temperature as the ambi-
ent temperature.)
Fuel economy, ECO pressure
At speeds under 160 km/h, the general tyre
pressure for full load is recommended in
order to obtain optimum fuel economy.
