I recently got a 98 YZ250. It's in need of new tires ... front and rear. I'm new to dirt bikes (been riding street for years) and live/ride in So California. What's a good tire for this area (and a newbie)? I'll be taking the bike to a track (Saddleback and/or Elsinore) and will ride in areas like El Mirage (desert) a lot.
