Anyone else going through trailer tires this summer?

Our roads in Pa are 65-70mph. If I went 55mph I’m a danger to everyone. If I would hit these hills with a 10,000 pound motorhome and 9000 pound trailer at 55mph I would be 45mph at the top. 18 wheelers would be ramming me in the azz as those guys are going at least 70-80mph.
I did the PA Turnpike weighting in at around 14,000 for 10 years. Know those "hills" well.
