I am planning a trip to Baja next this coming up March. I would like to take a poll of those who have been, and see the tires that have been used. I have been told to use the Pirelli MT 21, the Dunlop 606 and the 739 AT Desert, the Michelin Baja Dot approved. I guess what I am looking for is the stories to back them up! I also will be running Bridgestone ultra heavy duty tubes. They are the thickest thing around.
