If you are just climbing and trail riding then that is the type of tire to look at.

You could also look at radial tires, <a href="http://www.atvoutfitters.net/itp_mud_lite_xtr_tires.htm" target="_blank">http://www.atvoutfitters.net/itp_mud_lite_xtr_tires.htm</a>
I would suggest you are looking for something that looks like a aggressive car or truck tire.
As for tire size if you don't need the ground clearance then stay with a smaller tire 25 or 26. You will keep more of your power with a smaller tire and the lower your gravity the better. Maxxis Bighorn Tires seems to be a good all around tire. Or even GBC's dirt tamer <a href="http://www.atvoutfitters.net/gbc_dirt_tamer_tires.htm" target="_blank">http://www.atvoutfitters.net/gbc_dirt_tamer_tires.htm</a>
Do allot of looking though there is allot of types of tires and don't forget about how quickly they wear too.
