OnStar Diagnostics Report- TIRES.
Today I received an OnStar computerized diagnostic report via Emailed with green, yellow, red boxes along with a short note on each mechanical catagory. All is Ok but it says all 4 tires are at 30 PSi instead of 36 PSI.
I'm wondering if this could be a computer glitch or due to the colder weather now hitting New England. It's in the 30's here now in the early A.M.'s.
I guess I'll have to go check my tire pressure but @ 1700 miles it seems odd all 4 tires would be down exactly 6 pounds on my 2SS.
