How to repair the exposed line on the inner wall of bicycle tire

The separation of bicycle tire sidewall is a common problem. But it's easy to repair. You don't have to buy a new one, you can keep the tires and save money.

Remember, we are not talking about just repairing a pipe or replacing a flat tire. This is your repair when the sidewall of the bicycle tire is completely cracked. Usually, when the sharp rock edge is torn, it causes a considerable wound or tear, which often leads to the inner tube protruding. Sometimes you can ride a bike, but this is a trivial situation. You can't expect to go far like this.

How to repair the sidewall wound of bicycle tire

To start the repair, first clean the internal and external separated parts. Wipe gently with a damp cloth to remove any debris that may exist, such as leaves and gravel. We need to clean it so that the glue applied in the following steps can adhere correctly.

The wound in the picture is not caused by a stone, but by a broken beer bottle. My friend Rob Anderson happened on Katie Trail in Missouri. He is famous for riding 167 miles from St. Louis to Lake Ausak alone in one day.

Sew the wound on the sidewall of the bicycle tire.

The next step will make you feel like a doctor or a seamstress. Collect coarse needles and floss about 12- 18 inch.

Using a cross pattern, starting from the inside of the tire, sew the seam and pull the sidewall rubber together to copy its approximate original position.

Before you start, tie a knot at the end of the floss, away from the needle. This is why dental floss is fixed inside the tire. Finally, leave extra (about 2-3 inches) which we will use to fix the dental floss.

Be sure to put the needle in and out of the side wall, keep it intact, and stay away from the gap that the suture can accommodate. In other words, if the pin is too close to the crack, the damaged side wall may not be able to hold the pin in place.

Complete stitching to repair the segmentation.

After sewing, you should tie the ends of the floss. The first ending comes from the knot at the end of the floss we made at the beginning; The other end is the part left by the front end of the needle. It is very important to sew together to keep the stitches in place and prevent floss from loosening. A simple flat knot will succeed; Tie a knot inside the tire and trim the excess length with scissors or nail clippers.

Stick a patch on the inside of the tire.

The next step is to apply the car tire patch to the inside of the bicycle tire. These can be bought in auto supplies stores and are often called "radial tire patches" or something like that. These are not the patches you used on the inner tube of your bicycle. They have no elasticity. Their purpose is to hold the side walls together and provide an additional support layer to resist the high pressure of the inner tube, which will press on the side walls of the bicycle tire.

Use radial tire patch according to the packing instructions. Usually, this will involve putting down a layer of rubber cement and then pressing the patch on it.

The last step: daub the floss suture with cement.

Finally, take the cement, and then apply the suture with glue. This can not only protect the suture from being hooked or damaged when riding, but also help another layer of adhesive to help fix the side walls together.
