This set replaced a set of RE01R's. I drive them very aggressively in the east Tenn/NC mountains. Incredible traction off the line and in the corners. Have been caught out in deluges without problem. After sitting for a while they do need a few miles to even out. I've pretty much worn them down to slicks after 5000 miles but I expect that with my driving style with these tires. I am ordering another set. I do have a set of more reasonable all season tires for daily/off season driving. My car is supercharged with moderate suspension upgrades.
