Tires
I've got about 10,000 miles on my original 'D' rated trailer tires. On a -10,000 lb. 37' TT. I've always followed the 10% rule on my truck tires - inflate cold to 90% of max PSI to allow for heating...

Definitely upgrade the load rating tires and always inflate to max PSI. That rating allows for heat. Under and over inflation leads to tire failure.
X2. There's a website, rvtiresafety.net, by Roger Marble, a retired tire engineer. He explains things much better than I'm able, but comes to the conclusions offered above.
