I used to run Yoko 008Rs years ago on my old 911. While DOT legal for road use, there was no wear rating on them. If you got 5000 out of a set, you were doing really well, and they didn't like to be cycled a lot, so while the grip was fantastic, it would drop off with cycles. The sidewall was so upright and ridged, they probably inspired run flat tires. lol Nothing comes without a cost, and while they would hang on forever, when they did finally decide to let go, there wasn't a lot of progression built into them. Wooooohooooo, did you feel that coming Molly??? ;-) hee hee
