I am currently running Bridgestone M77 front and Dunlop 756 rear. I race Hare Scrambles in the NE (NJ, PA, DE) with everthing from rock/roots to sand. Most of my riding these days is in rocks and hard pack...all woods, rarely motocross tracks. It seems my front tires are washing out too much. I admit, I haven't paid enough attention to tire pressures as I should, so I'm sure that doesn't help. Obviously I don't think I can get a perfect tire to handle everything from rock to sand, but looking for what people have had good luck with. Thanks.
