Tire inflation
Got E rated tires installed, 80psi max, Tire guy said it would be better to run around 65-70 psi as tires heat up. Always thought I should run max cold rating 80psi. FW weight is around 9000 lbs hooke...

I have a similar situation. I have a 5ver the weighs in at 10,500 unhooked. Now I haven't yet weighed the axles or the truck axles. I just upgraded from GY Marathons with a D rating to Maxxis with an E rating. My problem is that the aluminum wheel is supposedly only rated for 65 PSI yet the tires are rated for up to 80 cold. I just completed a 2000 mile round trip to Mesa, AZ and ran the tires a 65 PSI cold. I have a TPMS and observed that the tire pressure grew from the 65 cold to as much as 80 PSI running down the road on a day where the ambient air temp was 65 degrees.
I bet your rims wouldn't know the difference between 65 and 80psi and probably aren't limited to 65lbs in any event.
