why different front & rear psi?

[dadominate]

still pretty new to the explorer game, why would they recommend different psi for front and rear tires? gas panel recommends 30 psi front tires, 35 psi rear tires, which doesn't make much sense to me. thanks.

well weight for one, then there is what axle is the drive axle and which is not.
but mostly based on weight.
