    I was referring to non mag racing. The Sport versions have aluminum wheels, open can motors and the 'good' tires. So far, for both SCX and Ninco tracks, the Spirit 303 rubber gives the best results, as long as it is trued, polished (with very fine grit sand paper to remove grain) and treated with NSR oil. Fly racing rubber is just as good, only a bit narrower and there are a few other options, but none better.
    Try different crowns. the 9/27 is driveable and with good brakes, the 9/25 is better, but you can easily go 9/24 or longer. The cars are light and the motors have a lot of torque.
    For mag racing... I don't know...

      Tim,

      What tires do you recommend for Ninco track without having to be treated?

        You could try some Slot its P6 or the newer versions (F22 possibly).
        MB Slot soft compounds work well also.
        But the Spirit 303 and the Fly racing rubber, when glued, trued, polished and treated a few times some oil, are still better, not only in terms of absolute traction, but also in the way they perform throughout a 5 min run and the ease of control when traction breaks.
        Remember, tire profile is important too, as you need a ground clearance around 1.2-1.4 mm between the motor and a flat surface. So, possibly you will need to true any tire.
