definitely a lot to think about.
IMO because most trailer and RV tires are throw away after 4-5 years if you want to avoid blowouts and flats. The question arises do I really need a top shelf expensive tire if they go in the trash in 4 years.
I was fortunate enough to get 7 years out of my Hercules however I have not been doing the traveling I used to do. I keep the tires covered when parked and keep checking the tread for cracks.
I like the idea of the F load range which I believe helps the side walls however I wonder what the speed rating is on those type tires or are they more for HD farm type applications or are they good for higher speed ratings (70-75 MPH)
The tire company I use tells me the Carlisle tire has improved a lot and are proven to be a good grade tire in the E load range. The Hercules also are good in that range as well
The good year endurance, I like the speed rating as others have mentioned but wonder if you are just paying for the name?

Looking at the Hercules site, the ST225/75R15/12 is is the only option for 15" and has a speed rating L, rated for 75mph. The 16" has 3 size options, all speed rated L and load rated G. Appears to have excellent reviews as well.
