Volvo 1990 780 Model
Tires for winter use:
Use snow tires fitted to the standard 15" wheels. Suitable tire size: 185/65R15 or 175/70R15 on all four
wheels.
Do not mix tires of different design, as this could negatively affect overall tire road grip especially
during slippery road conditions!
Studded tires should be run-in 300-600 miles (500-1000 km) during which the car should be driven as
smoothly as possible to give the studs the opportunity to seat properly in the tires. The car tires should
have the same rotational direction throughout their entire lifetime. In other words, if you wish to rotate
the wheels, make sure that the same wheels are always on the same side of the car.
Tire chains can only be used on the rear wheels if the chains do not project too far from the tire and
chafe against the brake caliper of other components.
Strap-on emergency chains must not be used since the clearance between the brake caliper and the wheel
rim is inadequate.
Note:
Regulations governing the use of studded tires may vary from one state or province to
another.

Checking and correcting tire pressure
Check the tire pressure when refueling.
The tire pressure should be corrected only when the tires are cold. With warm tires, correct only when
the pressure is too low. The tire temperature rises after driving just a few miles.
Vehicle Loading
The tires on your Volvo will perform to specifications at all normal loads when inflated as
recommended on the tire information label located on the rear facing side on the right front door. This
label lists both the tire and vehicle design limits.
