【Ready For Year-Round Use】Enjoy peace of mind that our 2.50/18 tire tubes won't easily burst or get punctured. Made of durable butyl rubber, they're reinforced against tears or punctures
【Butyl Rubber】High Butyl rubber content adds better air retention to inner tubes to prevent air leakage. Butyl rubber inner tubes can hold air up to 6 months without leaking. Traditional rubber's air permeability means you often need to reinflate your inner tubes as often as every 30-45 days
【Durable & Leak-resistant Valves】TR4 straight valves are fitted into thick valve seats for enhanced durability. Pure copper dust caps have built-in rubber seals that keep out dust and water can function as a tool to remove the valve core
【5 Years Longevity】Butyl rubber inner tubes are more impact and heat-resistant compared to ordinary rubber, meaning they can offer more than double the service life of ordinary rubber inner tubes
