I really like that tire....kinda a cross between the Zeon LTZ, but the mileage warranty of the Discoverer AT3. I have to agreed with Gantman here....Cooper seems to be making a quality American made tire.
What I'm really interested in hearing more about is you getting rid of the annoying 65-70mph vibration. I've had this since day one on my truck, and it literally starts vibrating in through the steering wheel, peddle, and truck around those speeds. Worst speed for me is literally 72 mph. I've suspected the Badyear tire and my dealer gave me that same excuse as they have had problems with the 20' Badyear tire.
Thanks for sharing....very nice. Just wished I had a Discount Tire near us, oh and that they made them with white outline lettering on the 20's.
