TyresTyresCARING FOR YOUR TYRESAlways drive with consideration for the condition of thetyres, and regularly inspect the tread and side walls for any signof distortion (bulges), cuts or wear.The most common causes of tyre failure are:• Bumping against kerbs• Driving over deep potholes in the road• Driving with under or over-inflated tyresTyre pressuresCorrectly inflated tyres will ensure that you enjoy the bestcombination of tyre life, ride comfort, fuel economy and roadhandling.Under-inflated tyres wear more rapidly, can seriously affectthe car’s road handling characteristics and fuel consumption,as well as increasing the risk of tyre failure. Over-inflated tyresgive a harsher ride, wear unevenly and are more prone todamage.Check the pressures (including the spare wheel) at least everyweek, when the tyres are cold - be aware that it only takes amile (1.6 km) of driving to warm up the tyres sufficiently toaffect the tyre pressures.Air pressure naturally increases in warm tyres; if it is necessaryto check the tyres when they are warm (after the car has beendriven for a while), you should expect the pressures to haveincreased between 4 and 6 lbf/in 2 . In this circumstance,NEVER let air out of the tyres in order to match therecommended pressures.The recommended pressures for cold tyres are shown in‘Technical Data’ later in the handbook.Care point: If possible, protecttyres from contamination by oil,grease, fuel and other automotivefluids.DEFECTIVE TYRES AREDANGEROUS! Do not driveif any tyre is damaged, isexcessively worn, or is inflatedto an incorrect pressure.Care point: Keep the valve capsscrewed down firmly - theyprevent dirt from entering thevalve. Check the valve for leaks(listen for a tell-tale hissing)when you check the tyrepressure.156
