Remove the rubber inner tube and cover from the packaging. When preparing to inflate the tube, lay the cover down with the bottom spread out as evenly as possible. Place the deflated rubber tube inside the cover. It is important that the nozzle of the rubber tube be positioned between the narrower spacing of the handles (at the front of the tube cover). This prevents the user from leaning against the nozzle with their backside. Pushing the rubber tube against the outer side-walls of the cover before and during inflation enables the tube to expand consistently within the cover.

Inflate the rubber tube using an air compressor, bicycle, or air mattress pump, so it appears snug within the tube cover. Our custom rubber inner tube takes shape quickly during inflation. Keep inflating tube until it fills cover evenly and tightly. Make sure that you do not over-inflate the rubber tube to the point of creasing or buckling. If over-inflating occurs, remove excess air until the tube is round and not distorted. Valve stem removal tools can be purchased at any hardware store inexpensively. A properly inflated tube has no more than two pounds of air pressure.

For tube longevity, it is ideal to leave the tube inflated inside the cover in an area where exposure to sunlight and air circulation is minimized. Avoid additional sources of ozone such as electric motors or equipment. Petroleum based materials should never be allowed to come in contact with the tube.

If there is no available storage space, inner tubes should be stored without sharp creases in the rubber. Do not tightly vacuum the tube. It is recommended to store tubes in a black plastic bag with the top tied or sealed, away from the noted sources of ozone.

To deflate inner tube, remove the rubber end cap by hand. Use a tire valve tool to loosen and remove the inner valve stem core. Remove the tube from cover, fold and curl as necessary to remove excess air. Once the inner tube is deflated, reinstall the valve stem core and tighten securely using the tire valve tool. Finally, fasten the rubber end cap for storage.

Note: Tube may naturally deflate due to seasonal air pressure changes. Additional air may be required before use.

**When re-inflating inner tubes, ensure the inner valve stem core is screwed in as tight as possible.**
