My dad corrected my tire pressure at a gas station in Reno and I've been doing it wrong for 15 years
He pointed at the sticker inside my door jamb and said I'd been going off the number molded on the tire sidewall, which is the max, not what my car actually wants. Dropped all four to the door jamb number and my ride stopped feeling like a shopping cart. Does anyone else go by the tire or the door sticker?
Honestly going by the max on the sidewall isn't gonna blow your tires or anything, it just rides a little rougher. Door sticker is the right call but it's not some huge life changing discovery either. People act like you've been driving on a time bomb when really you just had a bumpy ride for a while.
