Hi, I would be very interested to know what sort of Tyres Pressures you guys run at in your 3500kg Motorhomes? Even Quickfit who just fitted some new Michelin Aquilas Camping Tyres (215/70 R15 ) were confused. They contacted Michelin and they couldn't come up with anything definite. In the end they put 4.25bar (62psi) in the front and 5.5bar (80psi) in the rear. We're off to Spain in a few weeks and will be travelling at max load, so I wondered if anybody had any suggestions or recommendations or indeed experiences that would be helpful. Our Motorhome is a 2009 Swift Bolero Multijet Engine. 3500kgs. Fiat Ducato based.
