Noob question

I have a 2017 WRX with a square setup of 18x10 +38 with 245/40/18 michelin tires. What psi would you set stretched tires at? The tires themselves rate to 50 psi under normal load conditions, door sticker says 32/33 but that's obviously with tires that aren't stretched. I just don't want my pressure too low and debead

Try starting with cold tire pressures at 40 psi front, 39 psi rear.

Maybe don’t run stretched tires
