Yes sir, rear ski tail wear was an issue on my 1976 TX 250 I purchased used in fall of 1978. It had about 1200 miles on it. Not sure if it was from road running or what. I remember replacing the skis some time in 1979 with some Cat skis I got at Small Engine City in St.Paul (?). I liked the Polaris skis handling better as the Cat skis were heavier steering.
