Had'em on my 900 RZR, worked awesome! Loved them, very smooth and really worked in all situations. They work similar to the Term, but don't seem to plug up as bad in the mud and are smoother on hard pack. Better all around tire than the Terms, just my opinion. My 30" actually measured 30"s or a little more.
I've got a buddy running them. He has no complaints. They ride good on the hard pack and do pretty good on the mud. They don't clean out quite as good as the term but still do ok. The outbacks measure true as well. They look big beside other 30" tires.
Try Sayler motorsports in lacombe for pricing. I know he sells a lot of them.
The mudder Inlaws look decent. I'm not sure how well they would actually work in the mud with the one lug going backwards. And most of the other tread running parallel with the tire. That would help it ride smooth but not really help it paddle through the mud and water.
the only terminator tire i would buy is 32". all the other sizes have grooves in the lugs and they get chewed up and rip easy. had a set of 34's and after 300km pretty much every lug was starting to rip of. now have 32's with no problems. they have a solid lug. 32's also measure the exact same if not a little taller then the 34's.
