Hate to tell you this but being in the south I find that the tires are unrated for 65 mph in 100 degree weather. I think you should look at tires in the 3000# capacity or come Jul-Aug you will be looking at the same blowouts.
I run 3340# tube tires to get about 12000# in the heat. I end up with about 10k on trailer and 2k on the truck.
