How about you make sure whatever you are towing, and towing with, can handle the speed limits. If your tires are only rated for 55mph and you frequently dive on an interstate that is 80 mph…get tires and a vehicle that can handle 80 mph!
This is the problem in a nutshell. The vast majority of boat owners…
a) Have no clue what max speed their trailer tires are rated for.
b) Haven’t checked tire pressure since maybe spring and only then if a tire “looked low”.
c) Have only a guesstimate of what their boat weighs and are absolutely clueless as to the tongue weight.
d) Haven’t ever inspected their trailer tires for damage and dry rot.
I just recently saw another fine example of what happens when a guy tows too fast with an improperly loaded and trailer with suspect maintenance. A couple of weeks ago a guy pulling an enclosed trailer with 3-4 Harleys blew a tire on 35. The trailer started whipping and the Harleys broke loose. The whole half-ton pickup and trailer flipped and the trailer and it looked like the back of the pickup and trailer caught on fire.
80 is too damn fast for the vast, vast, vast majority of drivers out there based on their experiece and maintainace habits. Slow the hell down and enjoy not dying.
