it seems you are coming from a electric point of view so it doesnt help me much but oh well.
ive tried pvc.. way too slippery it just like ice, but i put stips of duct tape on the pvc and that worked pretty well for me.
im going to try and get some abs as ive heard that it has more grip than pvc
im still not convivced that the actual stage d tyres wont work with nitro
thanks for the good input though everyone
