The 65 mph max speed limitation is imposed on ST rated tires. Research of any tire literature will yield these numbers. On occasion when we had the ST's, we would also exceed the 65 mph max speed recommendation, whether that had anything to do with our tire failures is unknown and probably debatable. Our 614's are rated at a maximum speed of 75 mph, which gives a little better traveling margin for driving circumstances that arise, but rest assured that speed has never been approached. I typically set the cruise control at about 67-68 mph, and feel comfortable at that speed on the Interstates.
