Default 2012 Yukon Denali Tire Pressure

Quick question from a new member...and a GM Virgin...

My tire pressure on Delivery last week was about 38psi on each tire. The sticker inside the driver door says 32 psi for all tires. I called me dealer and he insists that 38psi is correct.

Can anybody weigh in on this?

Thanks in advance.

What does the MAX psi on the tires say?

It'* weird that a brand new vehicle came from the factory with a tire pressure greater than whats on the door. But, I have been out of the new car standards for awhile.

the sticker takes into account optional tires and the vin i would tend to agree with that more than the dealer. what size are they?

I had the 20" wheels on my Avalanche with the OEM tires. The TPMS would freak out if the pressure went above 40. I tended to run my tires at 36 PSI. I'll take a little stiffer ride to increase the fuel economy. I bet that'* why they set PSI so high. If you're running P series tires your max PSI should be about 44. You're fine.

tire pressures are more of a range than a exact number. like mouse said if it says 32 than sometimes you can get a bit of mileage from running 35-36 or so. as long as the tires arent wearing the center, indication of over-inflation, its fine. during the winter though i usually bring them back down to what the sticker says because you are compromising traction for mileage.
