Hi everyone. I'm looking for advice on tire pressure for city driving. With stock tires Subaru recommends 33 psi front / 32 psi rear.
I switched to Toyo AT2 215/75R15 and 33psi looks pretty flat. It looks more round at 42 in the front and 36 in the rear so that's what I'm running for now. Is there any more scientific way to determine proper pressure?
P.S. I'm talking about city driving here. Off-road I vary between 18-30 depending on the terrain.
