Very good point made here! Make sure there is not a mechanical problem causing or encouraging these flats.
A small burr on your rim may be enough when you add curb jumping into the mix.
When you say the "last 3 were pinch flats" , how often are they occurring? ...how many miles between flats?
AND, are you saying there were even MORE, just that the last 3 were the same?
Another thought.... what is the quality of the tubes being used? There are good tubes, and not so great tubes out there.
Good luck.
