My concern is about the stiffness. I know the wheels and tires will be well over what the axles are rated at. I have looked at a wheel with a Sailun tire and they're a little bit cheaper but they're only rated at 62mph. While I'm not going to be setting land speed records while towing the fifth wheel, I would like to have a speed rating over 70mph to accommodate for some extra room. My estimate is 65-70 mph.
So my question is would anyone else be concerned with the sidewall stiffness? In your opinion, would the ultra stiff sidewall tires cause frame issues or issues with anything else?

The Sailun truck or trailer tires both have a speed rating of 75 MPH. Here are a couple of examples.
