tires are very opinion based, and depend on the type of trails you ride. General allround tires i have used with great results are MAxxis Crossmark and Scwable Racing Ralph. These are both good for hard-pack conditions. Specialized roll-x may be a bit better for rocky conditions and the puncture resistance is excellent. IRC Mythos are also a very cheap-very good xc tire. But once again u need to test tyres on your trails and find out what you like. hope this helps.
