Every tire? I've never in 40 years of road biking have I ever had a "wiggly" tire except one and it was wiggly brand new. After reading this I even mounted my spare tire that I've been carrying in my seat bag for about 18 years just to see if being tightly folded for that long would cause problems and it's not wiggly either. I've used all sorts of brands too, so I can't say that ABC brand is the best because I never had one them that was wiggly.

Anyone else having this issue a lot?
