A study from the University of Bayreuth quantifies the rubber loss from mountain bike tires, finding that on average, 3.64 grams of rubber are lost per 60 miles of off-road biking. The research highlights the growing concerns around microplastics in the environment, particularly with the rising popularity of mountain biking in Germany, where there are approximately 16.6 million participants. Notably, tire wear is most significant in the initial 300 miles of use. This study underscores the environmental impact of sports gear in natural habitats.
'Mountain biking, a popular outdoor sport produces tire wear particles (TWP) directly in natural environments. This study quantifies microplastic abrasion from mountain bike tires in real-life usage.'
'On average these pairs of tires lost 3.64 grams of rubber per 60 miles of off-road riding. The highest amount of material loss occurred during the first 300 miles, tapering off after.'
