Default NEWBIE: Tire Problem Question?

Any help on this would be greatly appreciated as I continue to try to learn WHY things happen on my bike so I can do more things myself and stay out of the LBS!

I had a rear flat last week on my set of ProRace 2 tires. I changed the tube and rode a quick 20 mile ride on Thursday and 35 hard ride on Saturday. I just went out for a ride an about 10 miles in, on a decent, I felt a weird feeling from my rear tire. I cautiously braked and pulled over to the side of the road. I was SHOCKED to see that a 1.5-2 inch portion of my tire on one side of my rear wheel was bulging out from the rim??? I let some air out of the tire and just like that it popped right back into the rim. I used a CO2 cartridge to get about 90-100 PSI into the tire. It looked fine with no bulge any longer. HOWEVER, I went right home and the rear wheel felt weird but it may just be my mind playing tricks because of the problem.

So, can anyone explain to me WHAT HAPPENED??? Why it happened, how to prevent it and how to properly fix?

Thanks for ALL your help!!!!

I suspect that a portion of the inner tube was "pinched" under your tire bead. As you road along, the tire bead was pushed over the edge of the rim.
The Park Tool site instruction though long and detailed will help you prevent this from happening in the future.

I had a similar problem a while back. In my case, it was a pinched tube. In my case, I had to replace my tube.

I had a similar problem the first time I installed Michelin Pro Races, puncturing a brand new lightweight tube. Fortunately I was able to patch it and it's given me over 3000 trouble-free miles. If the hole is small, don't be afraid of patched tubes.

Well, it was bigger than a pinhole.... a break at the seam.
