Bicycle Tire Materials: A Deep Dive into Rubber, Nylon & Steel

The rubber is the outer layer of the tire, and it is what comes into contact with the road. It is made of a synthetic material called styrene-butadiene rubber (SBR), which is a copolymer of styrene and butadiene. SBR is a tough and durable material that is resistant to wear and tear.

The nylon is the inner layer of the tire, and it is what provides the strength and support. It is made of a synthetic fiber that is strong and lightweight.

The steel is in the form of beads, which are located on the inside of the tire. The beads help to hold the tire in place on the rim.

In addition to these three materials, bicycle tires may also contain other materials, such as Kevlar, carbon fiber, and latex. These materials can be used to improve the performance of the tire, such as by making it lighter, stronger, or more puncture-resistant.
