With the Easter holidays approaching many caravan and motorhome owners will be planning their first trip of the year.
Of the many maintenance jobs and safety checks to be carried out, making sure the motorhome or caravan tyre pressure is correct is essential for ensuring the stability of the vehicle.
Incorrect motorhome or caravan tyre pressure can have a catastrophic effect on the handling of the vehicle and can also lead to dangerous tyre failure, including blow-outs.
Tyres which are incorrectly inflated will also wear out more quickly and increase the vehicles fuel consumption. So having the correct caravan tyre pressure could also save you money.
The correct inflation pressure for caravan and motorhome tyres will be given in the vehicle/chassis handbook. It is not the same as car tyres. The ply rating is much higher (up to six or eight ply as opposed to just two), which means motorhome and caravan tyres can tolerate a much higher inflation, often up to 65 psi (cars are usually around 40 psi or less).
Motorhome and caravan tyre pressure should be checked and adjusted, if necessary, when the tyres are cold. Never reduce pressure when the tyres are warm, because they could be too low when they cool down.
This applies to the spare tyre too. The pressure should be set at the maximum required for the vehicle.
Whatever tyres are fitted to the towing car, caravan, trailer tent or motorhome, it is essential to the safety and stability of the combination that all tyres are correctly inflated for the applied load.
