I think Kelly Tire makes them, actually up close they have some soft rubber... I got over 27 on all mine now but, I have a Po Po with 589s on it, these are softer rubber than an ITP 589... I bet they'd pull good but, the tread on hard roads might be a bit of a wear... Here a rear shot of a set... They have an unlocked or broken center (Tread blocks don't straight-line around the center)... Probably go good however, there are many more with close designs... They have a good price - low..

 

I live in Alberta, Canada. I've only seen one of set of these, ever, and I've been frequenting quad shops for 20 years. There was a set of 26" Mudcats at a Tire Warehouse store. The lugs are massive and these are heavy tires. I would estimate that the 26x12x12 rears are 35lb each (more than the advertised 32 lb). Similar in weight to same sized Outlaws.

I was impressed. They look to designed more towards mud than trail riding and have alternating wide spaces between lugs to help with cleaning mud off of the lugs. The concentration of lugs along the centerline with help smooth out the trails. Do a search on this Tires forum because there are a few fellas with these tires (hopefully they'll chime in).

They look to be a very good tire but they are heavy. Good luck. GH

Also, you could PM Cupz. I know he has them on his TRV but said has not had them in decent mud yet. He said they do well in snow though.
