“As you can imagine, the tires go much quicker when you must rely on them as brakes. So in an attempt to offset the guilt I felt for burning through tires twice a month, I started thinking of ways I could reuse them. I had seen tire phone holsters at bike shops. But I wanted to make something that could be worn by almost anyone that served a useful purpose and had style. The most obvious thing that came to mind, given the shape of tires, was a belt. Given the nature of using repurposed materials, I wanted to use as little virgin materials as possible. So, after a few prototypes and mistakes, I have found the right process. I hand make all the belts individually from tires ridden in San Francisco.”
