Is anyone running any of GBC's 8 ply tires (i.e. grim reapers, spartucus, dirt commanders, etc.). I am very interest in these tires not only for the 8 ply rating but for the aggressive looking thread as well. Any info on them would be helpful.

 

My Bro in law has the Grim Reapers. I rode them and wasn't all that impressed with em. He has also had a few flats riding the same line as me through rockier sections of trail were my zillas were fine. IMO look at the pitbull rockers if your looking at spending that kind of scratch for radials.
