45PSI sounds awfully low for a Motorhome of around +3tonnesReading the original Autocruise owners manual the Michelin recommended tyre pressures for a Star Spirit at 45/45 approx… yet all around the vehicle drivers door it gives the tyre dimensions and 79/79psi… huge difference… anyone any thoughts??

What are the actual weights on each axle? What tyres are fitted? Thinking about my motorhome, 45 psi might well be appropriate for the front axle tyres for example whereas 79 psi would be rather high for the rears. I base my tyre pressures on recommendations from Continental (despite transitioning from Conti to Michelin) for the actual axle loadings; Michelin are reputed to recommend extremely high pressures on the basis that they assume that motorhomes are systematically overloaded.Reading the original Autocruise owners manual the Michelin recommended tyre pressures for a Star Spirit at 45/45 approx… yet all around the vehicle drivers door it gives the tyre dimensions and 79/79psi… huge difference… anyone any thoughts??

That's what I had on my Dually (6 Wheeler) LTMine set at 65psi on all 6 tyres.
Nope it is the opposite.The simple way is, pressure too low tyres will wear centre, to high and its the edges that wear.
