Many motorcycle repair shops throw partially worn out Tyre‘s as rubbish scraps which are collected daily by the waste management company and thrown at landfills. There are 10%, 20% and sometime 50% thread on the Tyre‘s which can be used for another 6 months. Is there any company in countries like Africa buys such Tyre‘s?
Visit some bike shows. The stunt riders like to burn out the rear tires making a smoke show.
