I have had this happen also. It comes from not keeping enough pressure in
your tire. When you go over small bumps or road obstacles watch your rear
tire where it meets the road. The tire folds in on itself creating a pattern
of diagonal lines across the sidewall of your tire. Do you get multiple
pinch flats? Try pumping tires up to spec (use a gage) before every ride. I
keep my rear tire at ~45psi, Maybe it's a little overkill but, I weigh 83Kg
never get pinch flats and my rims stay true.
