What air pressure are you running in your stock tires? Mine came set at 40 psi but I see 33 psi is recommended.

Mine also came well above 40 psi.
Dealer dropped down to 33 after first oil change.
someone wrote in another thread why they put so much air but not sure if the reason.
I keep mine at 33.

Same here. Try to keep it at 33, on a warm day it may get to 34.

Ambient air temp affects the tire pressure by approximately 1psi per 10degF rise/fall. If tire is in direct sunlight, it will not read accurately, so you should wait until early morning or late evening to set the pressures, so they are indeed all the same.
