I discovered a very small puncture on my rear tire. It is a very slow leak. I pumped up the tire and checked it the next morning and the tire was definitely flat. A close inspection of the tire revealed the puncture shown in the picture. It is small enough that a coat hanger wire will not penetrate the tire.
My question is what is the best option for repair? 1. An internal Patch. This would require removal of the rear wheel and taking it to a shop for repair and rebalancing. 2. Plug the tire. However in order to get a plug inserted, I would need to drill a larger hole to allow the plug to be inserted. I have plugged car tires before, including drilling a hole to get the plug to fit, and the repairs have held up well.
The tire has about 25% life left.
So what are your thoughts, and pros/cons.
