The front wheels on our van says 225/45-sr17 .......the back wheels say 255/40sr 17.. we carry 3 people at most some times 4,ive just had the wheels refurbished and the company that finished them say the pressure should be 32 bar all around, is this correct .thanks in advance yours sincerely simple head is there a mathamatical formula.

32 bar is not correct - 32 bar is approx. 480 psi!
3,2 bar at the front and, I think, 3.7 for the rears on standard 14s.

I have 215/65 16 on each corner and I go to 3,9bar for motor/fully loaded journeys.
