Find out what your tire is constructed from. The casing is especially important. How old are they? This can happen with very light tires, very

durability. All tires are a compromise between price, performance, wear, aesthetics etc. Another concern I would have is that these are very poor quality tires that are just breaking down. I would throw them away. Riding them does not seem wise at all. Rare as it is, a blow out can cause an accident. A blow out caused by a big bulge turning in to a hole suddenly

I would toss them and then report what kind they are and how long they lasted you. I would also like to know if you store them inside or outside when you are not riding on them.
Vred tri-comps $30 tires, stored in doors, 4000 miles, 3 years old. I have several sets of wheels, that explains why they were so old.
Which models were you using and how long did they last before they became this way? I sure want to avoid those. I was just getting ready to stock up on tires for the winter.
I like vreds, basically. The ricoso are the cheap wire bead ones. You get a couple thousand miles on them before the tread wears out. They don't last long enough to get bulges. The tri-comps are the expensive ones, a little heavy, but feel very good to me. Tread lasts forever, but you get those bulges over time. Usually you have enough cuts by that time, you want to get rid of them anyway. I had the worst luck with conti's. Two blowouts through the sidewall. They don't like high pressure, and they put all the rubber on the bottom.
