After all the questions raised I thought I would get to the bottom of what my, and others tyre pressures should be!
Our Fiat Chausson is fitted with 215/70/C15R Michelin XC Camping tyres - The Fiat 'specialist' service centre said "We set them all to the Fiat recommended 72.5psi" This rang slight alarm bells as how could the front & rear tyres have the same pressures when they are carrying different loads??
The answer? Go to the Michelin website and ask their advice, their reply was to ask the exact size and load ratings on the tyres, and to take it to a local weigh bridge and have the vehicle weighed in it's normal running condition.
The tyres are stamped with a load rating of 107/109 (For those that don't know the first number is for the load a tyre can carry as a single application, and the second is when fitted as twin/duals) and the axle loads were Front axle = 1480kg and the rear axle was = 1660kg which gives a total of 3100kg - our m/h has a Max Gross of 3400kg so we can carry another 300kg of crap if required!
The answer from Michelin was 50psi front, 55psi rear. So there you are, if you don't trust the experts then ask the manufacturer!! I'm told that some manufacturers have 'Load Tables' on there websites so you can look them up, but remember you need to know what the axle loads are on your vehicle.
