Filled it in, in my made extra safe motorhome calculator. Gave front 100 psi and rear 99 psi, so 100 psi all around .
Then maximum reserve, with still acceptable comfort and gripp.
In my calculator, I use an extra safe formula, wich leads to higher pressure then the officially used european formula, wich on its turn leads to higher pressure then the officially used formula in America.
But first I add 10% to the given loads.
I assume you weighed fully loaded per axle , and devided by 2 front, and 4 rear.
