Anyone with KO3 F Rated on 315/70R17 or 35”?

I’m switching to these Monday from my KO2 C rated. The one I have is too soft for towing my travel trailer. Even aired up.
What’s your experience with the KO3 F? And what PSI do you run for daily?

Interested also...I run 305's on 20's and the KO3s are only available in F which scares me for ride quality.

What's the weight rating at max pressure for your C rated tire?

I don't think I would want any more than an E rated tire on a F150?

Interesting, I tow my 26’ 7k max Travel Trailer with 315/70R 17 KO2’s that are C rated and don’t have any issues at all. Run them at 38 psi when towing and have a very steady towing experience. I did upgrade Rear Shocks to Bilstien 5100s.
