8.5" - 9.5" Heavy-Duty Scooter Inner Tube - 0° Valve

8.5" - 9.5" Heavy-Duty Scooter Inner Tube - 0° Valve. An inner tube keeps the air sealed inside a tube-type tire. It is an affordable, fast repair for a flat that keeps returning.

Check the size printed on your tire sidewall to pick the right tube, and confirm whether you need a straight or bent valve stem so it passes through your rim.

Product details

Keep your electric scooter rolling with this Extra-Thick Inner Tube. Made from butyl rubber, this tube is built to last and is considerably thicker than standard factory tubes, so it holds up better against pinch flats and punctures.

This version has a 0 ° Angled Valve Stem, which makes inflating easier on narrow 6-inch rims where straight valves frequently don't fit.
