You need to know the front and rear axle weights and it is common sense to get it weighed, preferably in 'holiday' mode when fully laden (around £5 to use a local weighbridge), before adjusting your tyre pressures.

Any guesswork will mean your tyres probably won't last as long and may wear unevenly.

With the tyres I have fitted - Continental (225/70 R 15C 112/110) - on my Pilote on a Ducato base and with front axle 1560kg and rear axle 1940kg, confirmed fully laden by a weighbridge, the recommended pressures are 47psi front and 61psi rear.

Michelin have always recommended the maximum pressure in their tyres, and many of you will continue to take their advice, but those who have actually weighed their vehicles and reduced pressures will know what a big difference to ride and comfort is achieved.

I'm never sure why Motorhomes are run at the tyres maximum, usually 80psi, which gives a harsh ride and on many roads could dislodge your false teeth and certainly rattle the chassis with the hard tyres and no 'give'.

Everyone has an opinion on tyre pressures but my Pilote has run well with minimal tyre wear over 30.000 miles and there's no reason why yours shouldn't do the same with similar pressures.

Hope this helps.
