But my best guess is that they would handle like slick tires on dirt. I know the stock Dunlops from my '11 don't like dirt roads very much.
Ultra performance tires are meant to be as slick as possible and give max dry traction by sticking to a high friction surface (tarmac/concrete) with just enough groves in it to pass a DOT inspection and wick some water from the occasional car washing puddle away.
