I'm currently running them on mine, having previously used Conti Premium Contacts in the same size. They've done a few thousand road miles, and a couple of track days. They were very impressive in the wet at Folembray, and equally didn't disintegrate in the heat of Clastres (day after the hottest day of the year in July). I don't think they're quite as good as the Conti's, but as an all rounder do pretty well. I don't think they'll provide as much grip overall as the A021s. I also have a set of 13s with Uniroyal rain expert (in 185/70/13). These are definitely overwhelmed by hot weather and very squeally when you press on a bit, but coped better than expected in snow and do very well in heavy rain. However my plan when they next need replacing is keep the Dunlops as the road tyre and get some NS2Rs or similar (in 185/60/13) for track use.
