bfg mud terrains with just under 20k
 

<TABLE><TBODY><TR><TD vAlign=top width="100%">I just wanted to hear everyones opinions on the bfg mud terrains. i have about 18k on mine and they might have about 25% tread left and are chopped pretty badly. what causes this chopping?
i loved the tires when they were new, performed great on road and even better off road, but now the on road ride is terrible, they hop at 35-40 and a bad vibration between 65-75. anything above 80 is like riding in a cadillac.
any ideas???

try re-balancing them, or a rotation.
