Phil, is your lack of recommendation of a 600-6 tire because you don't think they are safe or just a lack of experience?

It looks like the majority like the AERO CLASSIC SMOOTH TUNDRA FAA TSO TIRE 850-6 4 PLY. Given that these are not available for the foreseeable future according to Dresser and AC Spruce, as well as price and questionable clearance with Cleveland wheels and brakes, I am considering the AIR HAWK 600-6 6PLY TIRE. From what I've read, these are made by McCreary.

My flying is likely going to be mostly from hard surface with occasional soft or dessert surface runways. Is there anyone with experience with the AIR HAWK 600-6 6PLY tires?
