1982 Schwinn World Sport Bicycle Rear Wheel Tube Replacement

crwdns2915892:0crwdne2915892:0

If you find yourself having to constantly pump air into the rear tire on your 1982 Schwinn World Sport, then this guide is for you.

The tubing on a bike wheel is not visible on the outside of the bike and surrounds the tire rubber visible on the outside of the bike.

When the tubing is punctured, this will often lead to very low tires or could even cause the tubing to explode. Replacing the tubing on this vintage bike is slightly more difficult than modern bikes because this bike uses nuts rather than a quick-release lever.

Before starting this guide, be sure to inspect and remove any objects that may have punctured your tires such as glass, nails, rocks, etc.
