Provider ST 81 mph rated tires were one of the first, having the new design of tire strengthened for higher speed and much better reliability. These came on my FW when new, and served me well. The Carlisle HD came a little later, with similar design, higher speed rating. In recent years the GY Endurance showed up, with same design, plus higher speed rating. IMO, all 3 are good, and the GY is made in USA, if you don't mind paying a premium for that. I've no experience with the Carlisle, other than what I've read. I will be replacing 4 tires in the Spring. I will likely go with the proven Providers, but will look into a deal on the Endurance. I am not worried about paying a LITTLE more for USA made, as China did not send that huge stimulus check, that I actually donated most of to a relative in need of a dental crown.
