Tire Pressure Question
Picking up my new Reflection 29RS fiver with GVWR of 11k and 9100 dry tomorrow. I have a 2013 Chevy 2500HD Duramax with Michelin 18" tires, max pressure rating 80lbs. I normally kept them at 70# when pulling my 7k bumper pull. Should I take the tires up to the max 80# since I'll have an additional 2500-4000#?

If you're running them at 70 PSI while unloaded, you're probably running them overinflated. This will result in a rough ride and wear in the center of the tire. As stated by @jkwilson, use the pressures on the truck's door sticker. Unless there is a separate pressure listed for the rear when loaded, use the door sticker pressure all the time.

Yes - but perhaps not much if the tires are the same load range (probably E on the truck). To be sure, consider weighing your truck at the nearest CAT scale and inflating the tires per the load chart for that specific tire. You're shooting in the dark with non-OEM tires if you don't know your actual weights.

The CAT scale would give you weights for both the steer (front) and drive (rear) axles. You would divide each of those weights by two to get the weight on each wheel. The only "harm" from running over-inflated is, as I said, abnormal wear in the center of the tire. If there is a truck tire shop near you, they could probably look at your truck and tires and give you some good advice. It will be good to have CAT scale weights for your rig - both hitched and unhitched - to know what you actually have. BTW - your 29RS fully loaded will likely put somewhere around 2,640 lbs. on the pin (23% of GVWR).
