[. . . ] How self-sealing tubes work Bontrager self-sealing inner tub have Slime, a liquid sealant, inside the inner tube. [. . . ] After installing and inflating the tube for the first time, spin and rapidly stop the wheel at least three times before riding. · Sidewall punctures and pinch-flats may not seal immediately because those portions of the inner tube are not outermost. In this case, allow the Slime to puddle at the bottom of the tube (Figure 2) and then slowly rotate the wheel to bathe the sidewall with Slime. · No tube sealant can seal large cuts or large pinch holes, but in some cases these holes can still be patched. Before applying cement and patch, clean the patch area thoroughly with water to remove any Slime, and wipe dry. To help seal the puncture, rotate the embedded objects to the 6 o'clock position (Figure 3) before removing the object. · Since the Slime does not dry out, it is normal to see a wet spot on the tire where larger punctures have been plugged. If the bicycle sits for a long time without turning the wheels, a plug for a large hole may develop slow leaks as it dries out.
