Tire Fire was started as a platform for outlandish trail-side ideas. We like things that go fast and are obsessed with the art surrounding these speed pursuits. We're flying by the seat of our pants to bring you ideas that we think will help you enjoy the ride – whatever your speed. HOW TO INSTALL YOUR MUD FLAP: Curve the fender underneath the crown of your bike to get placement. Loop two zip ties through the top two fender slots and place around the fork crown. Then loop two ties through the outside slots of the fender and around your fork lowers. Pull zip-ties tight and get pedaling!
