Thanks for the reply. I've been tempted to try some bias tires just to get something with more aggressive tread without sacrificing too much tread wear or handling characteristics. I've had excellent results with the Shinko E705, but will probably go with something more aggressive next time. I'm just not sure whether to go with something like the Motoz, Heidenau, Mitas, etc, or stick with radials like Michelin Anakee Wild or Shinko E804-E805. I probably won't have to worry about it for a while if I don't put on any more miles than I have for the past couple of years...
