This is for all you scooter boys and girls who like to occasionally hit the trail or get a little wild at a camping rally. These are Golden Boy brand and are not intended for road use but are great on the gravel and muddy roads around your favorite camp site. In Europe we have started to see dirt tires on bikes that are doing Vespacross and it looks like fun. These fit great on standard rims but on my bike I run two wide halves to spread the tires out a little more for more traction.
