you'll probably be ok with standard tc tyres with belting securely fixed to the inside, i just used a fibreglass tape meant for rc planes and cyano'd it in place rather than relying on its own adhesive. no idea on the speed but it was quite quick, 4800kv sensorless on 4 cell, geared 32/72 in an old tc3, i had no way of recording speed at the time though. the big learner was to set dual rates, when you do your speed run you only want at most 20% of you normal steering, also normal tc body doesnt work, the car flips at speed, try to find something more like the shape of a 1/12 circuitbody!
