Tire air pressure question

[ZDA3]

I'm just curious why a newly installed set of tires would be inflated 33 psi for the front and 32 psi for the rear. I always assumed all 4 tires should have the same amount of psi.

Yep, depending on the weight of the car.... unless the tires are a completely different size or something *(like on a tractor )

The tire pressure is listed on the door jamb for the size of tires the car was delivered with and approved by the DOT.

All 4 tires same size of course. I guess 1 psi difference between front and rear tires may not really be relevant?

It's not. Just air them up to the recommended PSI.
