The Demolition Hammerhead Street Tyre are Signature Mike “Hucker” Clark tyres, fully designed by Hucker himself wanting something that will last and grip, coming in 2 different tread variations. Demolition Hammerhead Street Tyre Features Available in 2.25 and 2.4 in the lower profile Street (S) & higher profile Trail (T) versions. Lightweight, grippy, durable, full tread wrap, and an all new rubber compound that will keep you rolling on the same tire for a very long time. Hucker has been on his first sample pair for almost a year; if that’s not saying something I don’t know what is.
