I purchased ITP Terracross tires and they are great in sand, mud, woods and hard packed terrain. Incredible tire.

i prefered mud machines, but the 25" r getting hard 2 find anymore

 

589's... They are a Jack of all trades tire, and will seem to last forever...
ITP makes the 589 M/S (mud/snow), and TITAN makes he 589 M/T (mud/trail).. the titans are hard to find now a days..
The cons are, they are heavy. And they run a TAD bit short, depending on the rim and the air pressure in them..
They are a tried and true tire, that do great in all conditions.

 

Carlisle Mud wolf tires are amazing in the mud only problem is is that you will get stuck quicker they like to dig. I bought a set a year ago the tread depth was 1and3/4 inches and they still are. They do not wear much at all I have put 3000 miles on it in a year and the tires are still like new and i pretty much only ride in mud and swamps
