Traxxas 8974 Tires Sledgehammer N Bulidings Four AA batteries for theSledgehammer tires, supplied as a pair with foam inserts. Sledgehammer is Traxxas' aggressive monster truck tread, with tall blocky lugs that dig into loose dirt and grass where a shallower all terrain pattern would spin. The trade off is more noise and quicker wear on pavement. Foam inserts are included, which matters because inserts pack down with use and fitting fresh tires over tired foam gives away much of the benefit. Fits: Traxxas Maxx (89086
