128 Vehicle careWheels and tyresTyre condition, wheel conditionDrive over edges slowly and at rightangles if possible. Driving over sharpedges can cause tyre and wheeldamage. Do not trap tyres on the kerbwhen parking.Regularly check the wheels fordamage. Seek the assistance of aworkshop in the event of damage orunusual wear.TyresFactory-fitted tyres are matched tothe chassis and offer optimum drivingcomfort and safety.Winter tyresWinter tyres improve driving safety attemperatures below 7 °C and shouldtherefore be fitted on all wheels.In accordance with country-specificregulations, a notice indicating themaximum permissible speed for thetyres must be affixed within thedriver's field of vision.Tyre designationsE.g. 195/65 R 16 C 88 Q195 = Tyre width, mm65 = Cross-section ratio (tyreheight to tyre width), %R = Belt type: RadialRF = Type: RunFlat16 = Wheel diameter, inchesC = Cargo or commercial use88 = Load index e.g. 88 isequivalent to 567 kgQ = Speed code letterSpeed code letter:Q = up to 100 mphS = up to 112 mphT = up to 118 mphH = up to 130 mphV = up to 150 mphW = up to 168 mphTyre pressureCheck the pressure of cold tyres atleast every 14 days and before anylong journey. Do not forget the sparewheel.Tyre pressures 3 157.The tyre pressure data refers to coldtyres. It applies to summer and wintertyres.Always inflate the spare tyre to thepressure specified for full load.Incorrect tyre pressures will impairsafety, vehicle handling, comfort andfuel economy and will increase tyrewear.9 WarningIf the pressure is too low, this canresult in considerable tyre warm-up and internal damage, leading totread separation and even to tyreblow-out at high speeds.Tread depthCheck tread depth at regularintervals.
