Tire psi
My sticker on the door jam says 35psi. I have the stock tires on 275/65/18 GoodYears. And the last time I took my truck in for service they put 40psi. What's up with that?

I run 40 in the front, 38 in the rear, unloaded.
No tire roll during cornering and a little better mpg. 35 seems too low to me; the tires had such a wide footprint/bulge at that psi.

That's kinda what I was thinking. I went out an put the air up to 40psi all the way around. I'm going to go to the auto parts store in the way home and get some tire chalk and try the chalk trick

It simply means that the tires have been at rest and haven't built-up any heat as the result of running on the road.
"PSI COLD" does go up|down because of the ambient temperature changes, however, it's not related to a particular location/region. *And YA, I know the South is warmer (in general).
