Wheels and tyresThe handling and riding comfort of thevehicle is dependent on the tyre pressure and the type of tyres fitted. Read the following pages carefully: |

General informationYour vehicle left the factory fitted 195/65 R 15 90 tyres. Thetyre 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. |
Page 4:3 Tread wear indicators, Winter tyres |
Tread wear indicatorsThe tyres incorporate tread wear indicators inthe 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 have very poor grip when driving in rain or snow. |

How to improve tyre economy |
|
Flat spotsAll tyres become warm during use. On cooling, when the vehicle isparked,, 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 tyresTyres for winter use:The following snow tyres are recommended: 185/65 R15 and 175/70 R15. 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 wheels. 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. |
Page 4:4 Tyre pressures and wear |
Tyre pressure is important!Check the tyre inflation pressurees regularly, The correct tyrepressures 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. |
