What tires are you guys running? I have M.T. Drag Radials, and they are very inconsistent at the track. If I try to launch at more than 1-2 psi they spin. I've had the pressure any where from 13psi to 28. Are E.t. Streets good enough, or should I get real slicks? I have an extra set of wheels, so I wont need them for the street. Thanks Dave
