Cold, I run 35 front, 32 rear. I don't do this necessarily for ride comfort, I do it to keep the tires wearing evenly. I didn't look at tires good until first tire rotation I did @ 10k miles with 38psi all around and middle of back tires were very worn and front was even. I lowered all 4 to 32 after the rotation and everything evened out by next rotation and went back to 35 32 and went to 50k miles worn evenly before trading her in. That was on my 2018. My 2020, yes, from dealership they were at 48psi, lowered before leaving the lot. First rotation done @ 15k miles and wear couldn't be more even. 35 Front, 32 Rear. Ride feels good too. When towing my 6000# travel trailer, the backs heat up to about the same as the front, around 38, FYI.
