I've been getting a lot of flats lately, like 1 flat every 3 times I ride (only 8 mile rides). The most recent flat has made me wonder what is really going on... you see, this flat happened on my *first* ride, after putting on Armadillo tires (to prevent the flats). Since these were new tires, it was easy to check for glass in them. There was only one piece of glass in the whole tire, and it didn't even get to the inside. Now, this I find odd, but then I notice that this puncture (which was larger than any I've had before, it was about 1cm around when stretched), was located on the inside, that is, it should have been pressed against the rim.
You must be thinking that my rim spokes are exposed. They are not... there is not one "bulge", and I do have rim tipe all around. I checked the part of the rim where the puncture had been, and there was nothing there that was sharp. There are slight depressions though at each spoke (rather than bulges). But, again, they are covered and so are not sharp.
Is it possible that a tube,when fully inflated (it was at 125psi) may not be facing the right way? That is, when I put the inner tube in the tire, it is often crumpled up and twisted a bit, but I expect that to fix itself as I inflate it, no?
Please, someone give me the answer. I'm sick of changing flats in 20 degree (F) weather.
