New Valve Stems Are An Unnecessary Expense When Buying New Tires. https://youtube/watch?v=2S8IMcAITYY&list=UUxfMQdgjfsNbZ0kkKHSQ1Vw THIS IS NOT TRUE! - The valve stem is the primary air seal on a tire and wheel. Valve stems are made mostly of rubber, with a steel mechanism inside that lets air in and keeps it in the tire. - With age the rubber can get old and brittle and fail, causing a sudden loss of air pressure. - The valve core - the steel mechanism inside the valve stem - could rust or just wear out.
