Yeah I have had the good and the bad with Interco, I have never run one of there off road tires but I have run there drag slicks (M&H). I had 3 sets on a chevelle I used to run, first set great ran them till they were dead, second set put them on, did my burn out getting ready to stage and the car shook so bad in the burn out I thought I had broken something in the rear end. Took it home gave everything a visual once over found nothing wrong. Pulled the axles and droped the diff center section checked out the locker checked the axles for straightness, all looked good. I scratched my head for a while then decided to take the wheels and tires and have them put back on the balancer. Behold the problem, one of them now you could not put enough weight on it to get it to balance out. I had to buy a new tire because I had already mounted it and had already done a burnout on it, Oh well, no more shake. The third set were good for there life. I think I just got one out of a bad run. Still contimplating on getting the IROK's not sure if I want to balls up and go with 37's yet, but they are the only manufacturer I have seen that offer a 36. Thanks for the input.
