Can someone please tell me the correct tire pressure for the 20” stock tires. I’ve got one at 250 kPa (36 psi) and the others reading 295 (42 psi)...

Factory psi very high

I agree. The factory overfilled my tires to 42 psi upon delivery. The owners manual indicates 33 psi all around. See page 448 for the details! :tango_face_wink:

Mine were around 5 pounds over. You have to be parked to access the setting through the buttons on the lower left of the steering wheel.

Thanks. Anyone know how to change the units on the display to PSI?
Use the controls on the lower left of the steering wheel to change the display in the center between the tach & speedo. It's described on page 199 of the owners manual.

Mine was 40-41psi (hot) while driving and I didn't notice until I started playing with the center screen at the speedometer. It's 33psi now (cold) ... after 4mo of ownership ... lol

Th drivers side B pillar door jamb has a sticker detailing tire size and psi info.
This. Many folks will tweak that a little for personal preference, but the manufacturer specification on the door jamb sticker is what they recommend for a combination of performance and comfort.
