I don't think there's any tyres that can grip on the slipperly cobble/painted line/manhole cover.
the closest one I just managed to get a good grip on the painted line is a 2.35 Fat Frank tyres on the ATB, but that's about it.
Sure, nothing's going to grip on a wet manhole cover or a particularly thick, slick painted line (HPA, I'm looking at you). But I've had a couple of really squirmy moments on cobbles that surprised me a bit - maybe I expected better from a £30+ tyre that's designed specifically for wet conditions.
