Inner Tubes that Can Keep Up with Your Dirt Bike There are many inner tubes out in the market right now, but not all of them are meant for motorcycles, especially not for dirt bikes. AR-PRO ensures that every inner tube it manufactures can perform and even excel in their intended application. Made from high-quality and thick butyl rubber with threaded TR87 bent valve stems, these inner tubes had passed strict quality standards and in-house quality control. You can count on AR-PRO to do it right! Ride Safe with AR-PRO Inner Tubes Flats are frustrating especially if you are on an important ride. But puncture flats also get dangerous fast with explosive outbursts that can throw you off-course - literally. Whether you accidentally pinched the inner tube during installation or you punctured it while out riding, inner tube explosions can cause serious damage on your tires and wheel rim. And when you're riding at full speed, it can even cause injury. One way to prevent this is through the use of self-sealing inner tubes like the AR-PRO 3.00/3.50-12" Exact Replacement Dirt Bike Inner Tubes. Install inner tubes and ride without worries as these inner tubes' thick butyl rubber walls resist punctures and when they do get punctures, the rubber instantaneously creates an airtight seal around the puncture hole to prevent explosive air bursts. Ride Comfortable with Shock-Absorbent Inner Tubes These inner tubes will work in tandem with your dirt bike's suspension system to dampen and redistribute the impact and vibrations from jumps and bumps. With thin inner tubes, you'll really feel your bones rattling whenever you ride over bumpy or gravelly paths. These inner tubes will not remove the sensation but they will reduce it into a more comfortable level.
