The Most Common Reasons for Inner Tube Failure We’ve all been there, questioning ourselves if we’re to blame why the newly-installed inner tube won’t hold air. Were the holes or slits there before or did an error on your part caused them to appear? If the former is the case, you can contact our US-based customer service team. Our money-back policy will cover all purchases of our products within the 30-day window. But if the 2-pack AR-PRO 2.25/2.50-16” Off-road Motorcycle Inner Tubes arrived without issues only to fail later on, one or two of these scenarios may be the reason: ●Both over and underinflation can cause the motorcycle tubes and tires to fail. ●The tires may existing thorns or other sharp objects you may not have noticed during installation. Make sure to inspect not only the new tubes but also the existing tires. Also, holes on the inner side of the tubes may indicate damage or obstructions within the rim. ●Double slits are clear signs of a pinched rim. The inner tube may be too narrow for the tire, underinflated, the pressure too low, or an installation error could be to blame.
