Roll of the dice, 21, poker, slots, etc.. Same deal.. Will I win if I do any of those?? Dunno.. Maybe, maybe not.. Basically you are asking the same question.. ;)
No one on earth can tell you "sure, you'll be fine".. Or "Heck no, you'll end up in a burning pile of rubbish and kill everyone within a 1 mile radius if you do that"... :)
Most states have speed limits of no more than 70 mph.. Sure, there are those states that have no speed limits and all, but are you going thru those?
Anyway, only you know your comfort level and in "general" most OEM tires that are put on trailers are the cheapest and just barely clear the trailers load limit..
Personally, I'm comfortable with around 65 mph for hours at a time.. But, that's just me..
You can do whatever you feel comfortable with of course. And if that's 75 mph, well, there you go..
