The Mission inner tube is designed for the bigger tires that most street riders prefer. While it is possible to use smaller tubes in big tires, they have to stretch and thin more to do so, making flats more likely. Reduce your wrenching time and increase your riding time by running the proper size tube for your tire.

Had very good luck with these tubes and will continue to use them.. Try to keep some on hand.
