* Rubber: This is the primary material, providing flexibility, grip, and resilience.
* Steel: Used in the bead wires, which hold the tire securely on the rim.
* Nylon or Kevlar: Used in the tire's carcass (the inner layers) to give it strength and prevent punctures.
* Carbon Black: A black pigment added to rubber to improve its strength, durability, and UV resistance.
* Other Additives: Various compounds like silica, zinc oxide, and antioxidants are included to enhance specific properties like grip, wear resistance, and aging resistance.
So, while rubber is the dominant material, several other elements play crucial roles in making a bicycle tire perform well.
