Hankook Trailer Tires

First post on this site. I own a construction company, I have tried all kinds of tires on my goose neck trailers. I will run only one tire now, Hankook f19 maxi vantage made in Korea. These are the only ones I have ever had that will hold up for me.
We bought a Jayco fiver last month I ordered f19 for it.

To the OP I would put f19's on it instead of converting it to17.5. They are load range G 14 PLY 7.50 x 16" 105 PSI
