Genuine HPI quality spare part for easy maintenance and repairs. The Dirt Buster front Rib tyre in M Compound is the ideal match for the Block rear tyres. With multiple rows of ribs ably guiding the tyres, you are able to control the Baja 5B in nearly any off-road situation and on nearly any surface! Side grip is enhanced by the 'dash' ribs, allowing the tyres to grip surfaces like mud and grass. The solid ribs grip harder surfaces like hardpacked dirt and clay, and also work great on very loose surfaces like sand. This is the perfect off-road tyre for the Baja!
