Why did my tube blow?

possibly they weren't aired up enough?

when you put the new tube in did you check the side walls? I had a side wall blow out one day. It was a MASSIVE pop! Scared the jeepers out of me. After I changed the tire I noticed that the tube was bulging out the side again, and came to the sinking realization that the tire was toast.
Might want to double check so it doesn't happen again.

Something like that happened to me today... ~15 miles into what was supposed to be a 60 mile ride with some friends we hear my tire go in a pretty impressive whoosh, change the flat, couldn't feel anything in the tire so ffigure that whatever it was didn't stay in the tire. Pumped it up to pressure, and then as I was putting the wheel back on the bike had a pretty impressive pop. Turns out that something cut the side wall of my tire, so when brought up to pressure the tube started poking out the side wall and blew. At that point we knew that I wasn't riding any further on those tires and I had to call another friend to come and pick me up while the others continued on the ride. Went into the bike shop and $100 later I have 2 new tires and a couple of new tubes to replace the lost ones. Grrr...

But yes, check the sidewalls of the tire, that can cause flats like you described.

Thanks for all the advice.

After the flat was fixed, I finished the ride (another 12 miles) without a problem, even though the tire wasn't inflated to the proper PSI. I pumped up the tire last night, and everything seems to be okay - I don't see any bulges or anything. But now I'm worried that it could happen again. (I tend to worry a lot!). I'm just hoping that it was one of those freak occurrences, since, like I said in my original post, this is the first time (and I hope the last time) this has ever happened.

Overinflating a tire could cause it to blow off the rim. Underinflation would not, but could cause a pinch flat. Since the tire had been mounted for a year, it was probably not a bead seating issue.
