Yesterday I was doing some sidewalk riding with my road bike and there was huge gap between the sidewalk partials. I was going too fast to go around the gap so I decided to bunny hop it. Well, I didn't do it right, so the rear wheel hit the edge of the sidewalk part in a really direct way and it sounded loud.

Minute later I had a flat so I had to walk home which was a mile away. When I got home I tried to repair it and I saw 2 holes opposite of each other, indicating the pinch flat that everyone seems to talk about. What doesn't make sense to me is that I had at least 80 psi in the tire.

I repaired both holes, mounted and inflated the tire, and now there are little soft bumps on the opposite side of the tire where there were holes, spanning about 10 inches, so I guess the tire is ruined. It was one of those cheapo kenda, $15 , 27 1 1/4 tires. The wheel is in tact, thankfully.

Am I correct in assuming that it was a pinch flat and that those bumps that appeared are the result of pressure displacement due to impact? I know the answer seems obvious, but I was just wondering what your take on it is.
