his inner tube cannot be inflated a lot when it is not installed in the outer tire, otherwise it will cause irreversible damage!

Please use a manual air pump instead of high-speed air filling equipment such as air compressors or pumps.

Before inflating the GUSTAVO tube, turn the valve inward (towards the center of the tire circle). Inflate a small amount until the inner tube is round; this pressure should be less than 0.5 bar/5 PSI.
