I changed a tube for the first time a few months ago. Seemed easy enough. Today I did a 4.78 mile ride and when I got to the bottom of my front porch ramp I heard that dreaded thud and "pshhhhhhhhh" sound. This seems like an odd place for the tire to blow. Is it possible I did something wrong? Or just bad luck on the blow, but great luck at the timing of it.

Thanks in advance!
