I had a Maxxis on the rear wheel and that thing flatted like 2 times a week, for about a month. A mechanic in a gas station by the city limits (more or less middle of nowhere) said he never had seen such a thin, flimsy tube on a bike before (supposedly cheap tubes are much thicker).
I had to buy and have installed a cheapo nameless tube that day on the first crappy shop I found open, and even though the salesman himself told me my Maxxis was better, I still haven't had a single flat with this new tube (for about a month now). Maybe it was the installation or something?

Go figure.
