Yokohama YK520 tire sidewall cracking
These Yokohama YK520 tires were manufactured and purchased in 2008. In spring 2010 I noticed sidewall cracks in the most central part of the outer sidewall. There was this worryingly big crack, another longer but narrower crack on another tire, and a lot of tiny cracks (or crazing) on all tires. The big crack went all the way through the top layer of rubber, revealing an undamaged black layer underneath.
