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...

I use to inflate my load D rated tires to the 65psi max. But then I upgraded from D to E. The CAT scale says I have 7460lb load on my 4 tires. I ride slightly nose high, so the rear pair may carry a little more burden. According to my tires load/inflation table below, I should be inflating mine to 45psi. The max is 80psi. I have found 65lbs on the E tires a nice, smooth ride.
