1990 Ford F 250 Tires

I've had these tires almost a year and they're 2/3 gone. I drive conservatively. They don't like gravel or mud. Not much snow here but what little we have they side more then expected. I could not balance these tires with weights and had to use beads. They still hop a little bit around 62 mph. I would not buy these or any other Nexen brand tire again. My wife had Nexen tires on a car and they didn't least 17k miles on a brand new car! The rubber isn't any good.
