I've just replaced all 4 tyres with Michelin 215/70 15 Agiles camping 109Q with 60psi front and 66psi rear tyre pressures. Thought it would be a good idea to ask Michelin for recommended pressures and went to weighbridge for axle weights today. Emailed weights Front 1640kg & Rear 1790kg to Michelin who replied promptly with 55psi front and 80psi rear. It appears Michelin have joined other suppliers in quoting rear pressures at 80psi regardless of weight. Anyone tried at this pressure as it would seem a bit high.
