Stan’s Tubeless System provides you with the information and items you need to seal most tires and rims tubeless. When attempting this process, ride with caution the first initial rides to observe the reaction of your tires and rims. Due to the variety of tire and rim combinations, some may work much better than others. During your first few rides check your tire for leaking and correct air pressure. If your pressure drops too low there is a risk of the tire dismounting itself. The system allows the use of standard, tube-type tires, to be used in a tubeless manner. It should be noted that doing so exceeds the tire manufacturer’s original design intent and may void the tires warranty. Also, some tube and tubeless tires were not designed to be used with sealant and doing so may void the tire's warranty. Stan’s is not responsible for any damage to the tires and/or any injury or liability resulting from the use of a tire beyond the original design intent.
