Anyone have/had the FC II tires and have an opinion to share? I got a coworker at the fire station after my 31" MTZ'S. If I can find a decent AT tire for a good price, I might sell the MTZ's for a lighter and quieter AT tire. I live in southern AZ where the offroad terrain is dry, rocky, and sandy. I'll be be staying with 31" tires. Any opinions about this tire would be appreciated!
