This is a set of mounted foam tires for the Losi Micro-B. The set includes two front tires and two rear tires. HackFab's own design, these wheels have the same offset front/rear to keep the track width equal. They feature a glossy finish and will be available in white, fluorescent yellow, or black. The wheels are a little bigger than stock, with a slight increase in overall diameter as well. This allows more surface area to contact the racing surface and should be a game changer for carpet tracks or where foams would generally work better than the factory pin/rib tires. Of note, the front wheels/tires are 2-3mm wider than stock. This increases racing surface and should make the cars a little less twitchy in handling. These feature a 7mm hex and are a direct bolt-on for the Losi Micro-B.
