At the same time, the inertia of the outer ring of the wheel set is reduced, making the sprint and acceleration more sensitive. The inner tube should not be inflated a lot when the outer tube is not installed, otherwise it will cause irreversible damage. Before installation, slightly inflate to check for air leakage. When installing, please inflate 0.5PSI first, make sure the inner tube is close to the inner wall of the tire when inflating, and then press and adjust the inner tube.
