There Swamper Vampire, good luck on finding them thou under 120.00 buck per tire, i called all the places i seen them on the net that were under 100 bucks each and there out of stock for the 22/12.5-10s each place i called.
You should check out the GBC Gators, or Mud Machines, or Mud Sharks, Fox Swamps, Duro Excavators, Deestone Swamp Witch, Kenda Bear Claws Interco Swamp Lites (good for trails and mud i guess, but not for climbing)
Personally I would go for the Gators, Mud Machines and the Sharks, there easy to get, you go with a hard to get tire like i have you have to worry about flats all the time, or cutting the sidewall, I allways watch where i ride due to the tires on it now.
I DONT like ITP, thats why i didnt say any ITP products, I blew the damn sidewall out of a new Mud Lite XL that was on the Renny, and it was new because he had them on his Grizzly 450 and blew the same damn sidewall out on his, and i run the T9s wheels on the XX which bend if you look at them the wrong way, so yea, so IMO thumbs down for ITP. Only thing good they make to me is the SS wheels.
