They are typically made of metal or rubber and come in various types, including Schrader valves, Presta valves, and Dunlop valves. Valves play a crucial role in maintaining proper tire pressure, which is essential for safe and efficient driving. Regular inspection and maintenance of tyres valves are important to prevent air leaks and ensure optimal tire performance.
