These are real old school inner tubes like the ones that first invented all the fun. Durable and tough - ready for any season. <span class="a-text-bold">SAFETY VALVE STEM:</span> No more being poked with one of those long metal stems from the old days. Our unique rubber valve stem &amp; cap is engineered for safety. It is less noticeable and shallow to the body of the tube. It protects you from scrapes &amp; bruises. Youre going to love it! <span class="a-text-bold">UV PROTECTED / TEAR RESISTANT:</span> These inner tubes are UV protected so the sun won&#039;t harm the tube and cause it to deflate prematurely. The tubes are durable and very tear resistant and will not pop like many vinyl tubes. <span class="a-text-bold">PROPER INFLATION:</span> Be sure to properly inflate your inner tube to the fullest size as specified: 36&#034;, 40&#034;, 45&#034; or 68&#034; outside diameter for best results. Use the stop and start air flow method to prevent bulging. See our video on you tube. Note: the inner diameter will decrease as you inflate your tube. <span class="a-text-bold">*INNER TUBE COVER*:</span> We have heard you loud and clear and now have covers for the 36&#034; inner tube. The inner tubes cover will secure the rider and allow the smaller children to have more fun. At times, smaller tubes with light weight children may not go as fast as the larger tubes with heaver riders. A cover may be just the way to help providing a smoother, faster ride as it glides down the hill. Get them while you can!
