I wonder if they got cut and centrifugal force just finished the job? I do like my stock tires as they grip very well on road and even on most surfaces better than my zombie maxxes do. Sounds like an excuse to buy new stuff.
Yes, I supose it was the centrifugal force I was driving full throtle, by the way wich tires do you recomend? I have a set of rims ordered from tower by mistake, it seems I will finally use it.
I know the imex j-hawgs can withstand some abuse and they hook up pretty good in grass and on concrete. I don't drive in dirt or sand, so I really don't know how they work there. I spend most of my time in a park or a skate park.
What happened to the foam? Do you run w/ no foam on the rims (or just took it out for the pic)? If there wasn't any foam then the wheel could have cut the tire. If you had some foam in there, then I guess it was something else.
You asked about the Big Joe's. Yes, they are good for general use. Killahbz has them on his savage & I can vouch that they have been put through some pretty hard torture & are still running strong.
