Recently installed a nitrous kit on my mach and am trying to decide on what tire to run in the rear. The car has 4.10s in it so I'm trying to find a decent tire for occasional track days and the street. I've been looking at a M/T radial 275/60-15 and have heard good things. I know the 'shock' to the driveline is worse since the sidewall doesn't have the flex of a slick but I'm not a hardcore track racer so I figured radials would be okay at the track. Any input is appreciated thanks guys
