Hi all,

Last night my boyfriend and I were sitting in the living room and it was totally quiet. All of a sudden, we heard a pop and then air rapidly being pushed out of - you guessed it - one of our bike tires. I went to check them out and one back tire was totally flat. Before riding to work a few days ago my boyfriend's tires were really low on air so we pumped them up to about 110 psi, and his tires have a max 120 psi. I suppose my gauge could be off on my pump and we could have really overinflated but I've never had a problem with it before, and the gauge read properly this morning when i was leaving.

I know how to change the flat and all, but I'm wondering - does anyone have any other suggestions about what might have happened?
