I've had 4 flats in about 100 miles of paved road riding and 1 over night when the bike wasn't ridden at all. I thought the first was because I installed the tube wrong but since I'm having the same problems. I find it hard to believe I've gotten 4 new defective tubes and all the holes are toward the tire, not pinched. I've got pictures.

OK, not great a picture but see how there is a circle with small holes all the way around? most weren't all the way through but a coup[le of them are leaking.

There are 2 of those circles in this one, next to each other. My thumb is over the hole on the other circle.

This is with the air leaked out but you can still see the 2 circles and when I blow the tube up there are small holes around these circles.

This has happened with 4 different new tubes. 2 Bell tubes from WalMart and 2 from the LBS. I have new tires and new tubes ordered and should be in tomorrow. But I would like to have some idea of why I'm getting these flats. The tires are in good shape, I was riding on good roads and one new tube went down over night with no riding,
