I never understood this:

when you upgrade your tires/rims, and plus size them (in my case, going from 215/60/15 to 235/45/17) WHAT tire pressure are you supposed to use then? Some have mentioned a standardized convention to convert the pressures. The underside of the armrest compartment in my car has a label that states the fronts are to be filled to 33psi and the rears to be filled to 32 psi, but thats for teh stock wheels (size is listed directly on top of these pressures). The place i bought my tires from didnt even know and told me the wrong pressures, and as a result, F*CUKED up my tires as the middle is wearing to nothing (2/32) and the outside edges are still 5/32. Am i supposed to use the stock tire pressures, or is there a website/retailer that would know what exactly to fill these plus sized tires to? Thanks!

Run 33 up front and 29 in the rear. Thats what Nissan says for all SE models. The tire pressure depends on how much your car weighs, not how much the tire can handle. So if your Max weighs about 3,000 lbs and auto mfg. say 33/29 is enough pressure to handle that much weight distributed according to vehicle load. FWD=Heavy front end. Thats why were a bit more up front then a RWD car.
