The tire and informationtable containstherec‐ommended tire pressuresfor cold tires,the max‐imum permissible load andthe maximum per‐missiblevehicle speed.
The tire pressuretable containstherecommen‐ded tire pressuresfor cold tires undervariousoperating conditions, i.e. loading and/or speedofthevehicle.
Increasedvehicleweight duetooptionalequipment:the combinedweight of allstandardand optional equipmentavailableforthevehicle,
regardless of whether it is actually installed onthevehicle or not.
Rim:the part ofthe wheel on whichthe tire isinstalled.
GAWR (Gross AxleWeightRating):the GAWRisthe maximum permissible axle load. Theactual load on an axle must neverexceedthegrossaxleweightrating. The gross axleweightrating can befound onthevehicle identificationplate onthe B‑pillar onthe driver's side.
