Yet another tire thread - Cougar X-Lite 26SAB
I know, I know ... not another tire question thread. Sorry, but there's so much out there that I get lost (and disheartened) before I can read it all. Simple question really. GVWR of my 5'er is 9...

I don't buy any of that.
The E rated tire has a stronger carcass and additional belts, which makes it resist damage from road hazards, bruises, and twisting. The same construction that makes it able to resist higher internal force (air pressure), makes it able to resist external forces.
I always run my ST tires at, or just below, max rated pressure. There isn't any reason not too. They will run cooler, pull easier, and handling is not an issue with a trailer.
Since there is no such thing as a free lunch, everything you say about the stiffer tire and IT'S ability to resist road issues does mean more force is transmitted to the fiver suspension, frame and body. There is a reason why tires are not solid and having a tire stiffer than needed comes at a price.
I agree with you Dayle. I think it is important to have adequate tires, but if over doing it, with too much tire/air, you are just beating/shaking your RV for no reason, other than maybe a slight mpg improvement. I would rather run the proper tire, with full air pressure.
