We have five cars using Yokohama AVS ES100's, including mine. We are all very satisfied so far. I recommend them. They even kept a nail from going all the way through in one of my rear tires (which are $175 because of the size). They definitely got my vote. These are fairly new to the market, so don't expect many votes for these yet.
Kuhmos are cheap; no wonder why they are leading the poll right now.
