I pop my tires a LOT, this week alone I can recall 5 flats. So today I go into the store, get a new inner tube and let them replace it (even though I can change a flat in my sleep at this point) but i figured maybe they could do it better and i would get an extra day or 2 out of my tire before patching it up. So after i bike the 10 blocks or so to class, being extra careful, like slowing down when i see a crack in the sidewalk or whatever. get to class, lock it up, and come back an hour later to find it flat... i don't know what to do any more, i love biking, i bike about 100 miles a week, but i cant handle this anymore.
Is there a such thing as a heavy duty inner tube? or can anyone make any other suggestions? I'm pretty sure I'm changing them right, and its just my weight/amount of use I put on it (although who knows..)
