Eurovan air pressure

MNit what air pressure do you drive with your Eurovan? I drive with 2.4 bar in front and 2.4 bar in the back. So 2.2 bar + 0.2 bar. Is this optimal? Can you enter 3 bar in the back, if the “case room” is not loaded? Is that true that you should give 0.2 bar pressure more? Why? What pressure do you drive? Does this happen to the tires? I have Michelin Pilot Primacy in the dimension 215/65 R15 H on it. How important is the tire pressure in the first place? What happens? t if you drive with too much/too little air pressure? Premium tires can’t normally burst, can they? They’re tested? (i.e. Michelin, Conti, Pirelli, Goodyear…)? That’s only available at “no name”, isn’t it? Thanks for your reply mfg franz
