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...

It is very simple:
1. weigh your rig - axle weights are fine, but individual wheel weights are better.
2. Find the weight/pressure chart for your brand and size of tire - they are all out there on the web.
3. Set your pressures cold according to the chart and relax.
4. Get a good tire monitor system for peace of mind if you are rolling up miles.
This is what Michelin says about RV tire inflation:
An underinflated or overloaded tire will build up more
heat that could go beyond the endurance limits of the
rubber and radial cords. This could cause sudden tire
failure. Underinflation will also cause poor handling, faster
and/or irregular tire wear, and can decrease fuel economy.
Overinflation, on the other hand, will reduce the tire’s
contact area with the road, which reduces traction, braking
ability, and handling. A tire that’s overinflated for the
weight it’s carrying is more prone to a harsh ride, uneven
tire wear, and impact damage.
