The Nankang AR-1's are supposed to be quite good. The Nankang NS-2R are also meant to be quite good, although less hardcore than the AR-1. Apparently the NS-2R work better from cold and in the rain, but ultimately don't give as much grip in the dry as the AR-1, but they are a lot cheaper as well. So if it was me I'd probably get the NS-2R.
