Tire Repair

I had a hole in my back tire and I repaired it a few days ago and the patch has held pretty much ever since but today I rode the bike to the store and it was fine then I rode it to the store again and when I came out my back tire was flat again. Of course I didn’t have my pump with me so I had to walk home.

When I got home I took the tire apart and put it in water and the bubbles were coming out of the side of the patch which means I didn’t put the patch on right. So I took the patch off, sanded the glue down as much as I could then repatched it and held the new patch on really tight and I’ve let it sit on the table in the back yard without pumping it up to see if it will stick better. I’m gonna go put it back together soon so I can see if it worked or not.
