Tyre pressure 341 Determining tyre pressure imum permissible axle loads given in the vehicle documents. R For off-road driving, the minimum tyre pres- sures must be set in accordance with the "Tyre pressure reductions for off-road driv- ing" table ( Y page 352). Example: tyre designation X Read tyre size : and tyre load-bearing capacity ; on the tyre. X Determine the approved gross axle weight of the corresponding axle from the vehicle identification plate ( Y page 356). X Look up the specified tyre pressure in the table ( Y page 342). X Check and, if necessary, correct the pres- sure of all tyres. Wheels and tyres i Correct the tyre pressures for each axle on the vehicle.
R The tyre pressure values are given for a ref- erence temperature of 20 †. R In the following tyre pressure table, the tyre pressures are listed for the permissible vehicle weight. R Differing values for the front axle take account of the fact that the front axle is not normally fully laden. The maximum tyre pressures on the front axle are only required if the axle is loaded accordingly. The figures given are tyre pressure values for on-road driving. If in doubt, always set the tyre pressure to the next highest value. This is provided that the tyre load-bearing capacity is adequate.
In the axle load data ( Y page 356), the higher value (on the right) for the front axle, in conjunction with the rear axle load, corresponds to the max- Z
