I have owned this vehicle for 6 months. Just checked tire pressure for first time in order to adjust for winter. Vehicle says 38 front and 44 rear. From dealer they were 34 front and 40 rear. I added air to put at recommended settings. Just wondering what other people are running for tire pressures?

That sounds too high. The correct tire pressure is stated on gas cap opening. Mine is 31 front and rear, which I suspect yours is likely the same too. Adjusting to the correct tire pressure, as stated on gas cap lid, will make a huge difference in drive quality and fuel efficiency.

Thanks, I finally figured out that the correct tire pressure was in the gas cap. Big difference. rides like it is supposed to now. Do you know how to check the tire pressure with the onboard system? I found it in the manual, but I cannot seem to figure out how to get to it.

It’s in your driver screen menus. Use menu button on steering wheel and scroll to the right to “Service”, press enter button, then scroll down to tire pressure. You also set your pressure from here.

Very confusing with 3 different psi recommendations. They should have just one sticker in the B pillar instead of the fuel door.

Hello... Just reading through... Mine were 44 all around.. think they are right... Going to check them soon.. Did not check or change yet for the same reason you have... what should they be... Very confusing with different psi recommendations where ever you look. Manual does say Gas door for info.... Around here the pressures change a lot with out side air swings. We go from 40 to 20 outside from day to day... Later..Gerry

I adjusted my pressure to 35 in all tires. this works pretty good for winter and keeps the pressure relatively close to the 31 lbs that is suggested in fuel door. with -28 they were down to 36 psi, but with temps in the 20's they stay at 31.

On my gas door.. It appears that there are four settings. Two settings for 'road' tires and two settings for 'M+S' tires. Now they have on the far left side what looks like little people. One line has like three people and the line below it has like six or seven people. This I believe is the load in the vehicle Three being lightly loaded and six or seven being heavily loaded. And looking at the tire pressures they coincide with the load... Best I can do... Took me awhile. ...Gerry

What is the pressure do you use now ?

I have 40 right now all around..Cold and winter here. 20 to 30 degrees f.

Also... Just order some tread depth gauges. Will be watching the ware from center to the edges. That should indicate over inflation to load. ... Gerry
