The TT owner's manual clearly states that the TT tires should be run ay 65 mph or less. The tires are rated for service at 65 mph. There is no indication of what their maximum speed is.
Maybe yours are. The ST tires on my 2017 Rockwood are rated for service at 75 mph, designated by "L". Forget the TT owners manuals which are generic.
As are the tires on my 2017 KZ, I've also run across M and N rated tires in D and E load rating so it's quite possible to have tires rated to 80 MPH not to mention LT swaps. Personally I don't drive over 70 (and cruise at 67) so it's academic, but it's nice to know there is spare capacity.
