Asked the speed limit question to Randy at the factory repair facility recently, was concerned about my new roof as well as tires, etc. His immediate answer was tires not rated for higher speed were the limiting factor.
I do not go over 65, and will upgrade the tires before my long trip this year. Was going to G-rated, but the link you sent and conversations with some other brand owners in May have me wanting a higher rating.
