Cup fan I can't tell you about your tires.
What I can tell you is what "I" do. I've ran every type and brand of ST tires made and known to mankind. I always fill them to max pressure on the sidewall and many times 10 over. I always run fast. Most of the time 70+ and always in hot weather since I take all my vacation time in July. A few times 80 in hot weather for hours at a time.
My score card? Blew one tire in 35+ years of towing. And that was almost for sure a nail or screw that I didn't catch in time.
Do I suggest to do what I do? Nope. Just stating my experience to show that if you go over 65 and have my luck you will be fine. :)
