What size are the tires and how much pressure are that rated for? There is a huge difference between 80 and 100 psi. From the picture it looks as if the flat could be a result of the tube being pinched between the tire and the rim on impact due to insufficient pressure. The tire looks to be a road bike tire that would normally be run in the 100 - 120 psi range. I suggest that you fully inflate your tires before each ride. The pressure that is right for you depends on what the tire is rated for and on the total weight of the bike, rider, and equipment. My body weight is 165# and I run 120 psi in the rear tire and 110# in the front, 700c x 23 tires.
