this is probably a noob question, but i thought i'd ask anyways.

if i have non-oem tires that are the same size as the oem ones, is it standard to just use the tire pressure specified on the door area? or do i need to check with the manufacturer?

oem I find to be too low sometimes, I run 35psi or so on all four-sometimes more. No need to check with the manu..

Generally there is a pressure rating printed on the side of the tire. That is probably the best to go with.

i tried checking there, but all i could find was a max pressure. i'll check again though.

thanks for the help, guys.

A max pressure is all you will find on the tire itself. Don't use that as an actual inflation pressure.
Use the recommended pressures on the sticker (or in the owners manual) as a starting point. You can gradually increase them by a few psi to obtain the desired handling vs. ride quality compromise. If there is a differential between front and rear in the OEM specs it's best to maintain that.
