Proper Tire Pressure...
I am changing all my tires on out 5ver from STs to LTs. I have looked for an answer to my question but to no avail, so I will try here, you have all been helpful in the past. I'm going to put 80l...

When we changed our Jayco 285RLS with 5200# axles over to a LT235/85R16 LRE BFG's. I found that 70psi was the max I could run and make tread contact all the way across. I started at 80psi and worked down 5psi at a time. We ran those tires 2 years on the Jayco before selling that trailer. Kept the tires and they have been under the Mountaineer now for 2 more years (@80psi).
Ding Ding we have a winner!
This person understands that you DONT HAVE TO run max psi.
I will drink a beer to that! Ho! We did that Sunday afternoon didn't we!
If one has around 10K on the axles like the OP and myself, and these tires are good for two fully load axle with 12K on them at 80 lbs inflation, why would you put 80 lbs in them with 10K on the axles.
I asked this question of Michelin CS several times and always got the same answer. Over inflation decreases the contact patch and braking, and increases the chance of impact damage! I run 71 lbs in the same tire that OP installed and trailer is similar in size and weight. Has been working great for many years.

I have BFG 235/16's also on a small 26 foot 5th wheel and 70psi is about perfect for it.
I did an simple test my dad showed me, paint a white 2" stripe across the tread of your tires and run the car/trailer a few miles loaded. It's easy to see how the tread is wearing by taking a look at the wear of the stripe. This works for checking tire alignment as well. Tires have to be fairly new for this to work well.
