I've been looking for the holy grail of mud tires for a long time (22x10-11 with an inch of tread) and they totally don't exist (at least not in Canada)... You either have to get 10" rims to get the 22" or get 24s to get the big lugs. Totally sucks.
Anyways yeah they are Titan 589s but they are 24"s
Friend just got these for his 700XX after seeing this Shee, this is what you need, 22x11-10 Swamp Witch <6 ply, 1 inch tread, 21lbs> made by Deestone get them on Ebay, very nice tires. $153.00 shipped.
I would of got them but i got a pair of Vamps for like 15 bucks more, I will get some pics up.
