I've done pretty well, but I had the "walk of shame" 3 or 4 weeks back. My wife had two flats within a couple of days, which used up the two spare tubes I usually carry. Then I shredded a tire. Replaced. Rode to work. About halfway home on my 6 mile ride I noticed my new tire going "thump, thump, thump". I had just enough time to think, "why didn't I notice that on my way in?" before the tire jumped off the rim and the tube exploded. Walked it home, after getting the tube untangled from the axle and replaced. Next commute it hardly went a quarter mile before it did the same thing. Ended up driving
to work that day. Replaced that tube and re-installed. It seems to be stable now, it's been about three weeks or so. Still, I haven't been riding very fast. That kinda shook my faith.
Just today, as a matter of fact, I restocked my bike with two new spare tubes and a pump.
