how much air are you putting into the tires?
My DH put 120 lbs of air into the tires for my hybrid and I got flats 2 days in a row. the second day I noticed that the poor tube had been trying to squeeze through the spokes holes.
THen I asked him how much air he was putting in. I think max for those tires was 70lbs.
that solved that problem.
