Wheels and tyres

The handling and riding comfort of the
vehicle is dependent on the tyre pressure
and the type of tyres fitted. Read the

General information

Your vehicle left the factory fitted 195/65 R 15 90 tyres. The
tyre desigination is coded as follows:
195   tyre width in millimetres
65     tyre profile. Section height to tyre width expressed in percent
R       radial tyres
15     rim diameter in inches
90     code number for maximum tyre load, in this case 600 kg
H      speed rating. Indicates the maximum speed the tyre is intended
         for. In this case 210 km/h.

The tyres have good road-holding characteristics and offer very safe
handling on dry and wet surfaces - even at high speeds. It should be
noted, however, that the tyres have been developed to give these
features on snow-free surfaqces. for optimum road holding on icy
or snow-covered roads we recommended Volvo winter tyres.
When replacing tyres, be sure that the new tyres are the same size
(designation), type (radial) and preferably from the same manu-
facturer, on all four wheels. Otherwise there is a risk of altering the
road-holding characteristics of the vehicle.

Tread wear indicators

The tyres incorporate tread wear indicators in
the form of sections of the tyre pattern with
a slightly less deep bed. When these sections
become prominent there is only 1/2 mm of
the tread left, and you should change the
tyre as soon as possible. Remember that tyre
treads worn down to less than 1/2 mm
very poor grip when driving in rain or

How to improve tyre economy

  • Maintain correct inflation pressue
  • Drive smootly,avoid fast starts, hard cornering and heavy braking
  • Remember that tyre wear increases with necessary.
  • Do not change round the wheel alignment is very important.
  • Do not scape the tyres against the kerb when parking.
  • Unbalanced wheels impair tyre economy and driving comfort.

  • Flat spots

    All tyres become warm during use. On cooling, when the vehicle is
    parked,, the tyres have tendency to disort slightly forming flat
    spots. These flat spots can cause vibrations similar to the vibrations
    caused by unbalanced wheels.
    They do, however, disappear when the tyre warms up. The tendency
    to form flat spots depends on the type of cord used in the tyre.
    Remember in cold weather it takes longer for the tyre to warm up
    and consequently longer for the flat spot to disappear.

    Winter tyres

    Tyres for winter use:
    The following snow tyres are recommended: 185/65 R15 and 175/70
    The tyres must be fitted on all four wheels.
    Only some rims from other volvo models can be used. Check with
    your Volvo dealer.
    Studded tyres should be run-in 500-1000 km (300-600 miles)
    during which the car should be driven as smooth as possible to give
    the studs the opportunity of bedding properly in the tyres.
    The tyres should have the same rotation direction throughout their
    entire lifetime.
    In other words if you wish to change round the wheels make sure
    that the same wheels are always on the ame side of the car.
    Note: Regulations governing the use of studded tyres vary from
    country to country.
    Snow chains can be fitted on the rear wheels provided they have fine
    links and do not project from the tyre so that they scape the brake
    fittings or other components. Do not attach snow chains to the front
    Volvo dealers can supply snow chains specially designed by Volvo.
    Note: Do not exceed 60 km/h if snow chains are fitted. On no account
    may grip links be fitted as the space between the brake components
    and the wheel rims is inadequate.

    Tyre pressure is important!

    Check the tyre inflation pressurees regularly, The correct tyre
    pressures are shown in the table on the right.
    Incorrect type pressures adversely affect the handling and ride
    of the vehicle and cause rapid wear.
    Note that the values shown in the table refer to cold tyres.
    The tyre temperature rises after driving only a few kilometres.
    If the tyres are warm, correct only when the pressure is too low.
    Inflation pressure can also be effected by the air temperature
    it is therefore advisable to check your tires outdoors
    while they are still cold.

    Cold tyre pressures in kPa (psi)

    kPa:kilopascal,100 kPa = 1 kp/cm² ,= 14 psi

    Set tyre pressure at 30 kPa (4psi) more than values shown above if you
    intend to drive for long periods at high speeds (more than one hour at
    speeds in excess of 160 km/h).
    This does not apply to the special spare.
