Challenge Range - Upgrade Bikes
To understand what makes Challenge Handmade tire construction special you must first understand the basics of bicycle tire construction.

99% of the world’s bicycle tires are wire bead clinchers made with a synthetic butyl rubber saturated nylon casing and a synthetic butyl rubber tread that is cooked or vulcanized into a horseshoe shaped circle to be mounted on a steel or alloy or carbon clincher rim.

This system maximizes the durability and long life and minimizes the cost of the tire.

Car tires, motorcycle tires and giant truck and tractor tires are all made much the same way.
