The last one I got occurred right on the rim's seam, and broke the seam on that side.
Incorrect. Pinch flats are caused by an under inflated tire. Such as in mt biking. Both side of the rim bottom out against a sharp edged rock or such. The rim on each side hits against the hard object and pinching both sides of the tube. Fact.
