yea, i did this too a stampede and put a stinger pipe on it, it kept wheeling over backwards i bought a wheelie bar for it and i loved that truck, i could nail it and ride a wheelie up the whole road. it was awesome, it has a os.12 i think, with a tuned stinger pipe, it had 2.2 wheels, "BUT" i took some tires off a nikko truck i had, they fit on the wheels in the slots tight enough they never needed glued and dropped the tire profile prob. less than half the tires didn't really look goofy, there was enough profile they still looked like monster truck tires, but it had more torque than anything i ever drove it was awesome.
