i just put them on, and went for a ride in the mud. these things are great. i got 27"s on c-series rims, from atvgear.com for 620.00 mounted and delivered. i am very happy with there service

 

just came back from a 30 mile ride in the snow. these things are great!!!!!!!

 

I have the same tires on my AC 500i. My riding partner who owns a Rincon, just put them on it and didn't like the ride but likes the grip and transfer of power he gets. My brother has Black Waters on his Honda Forman and I doubt he could keep the pace in the mud, sand and snow. We'll find out later but I am very happy with the 589 M/S. Stock size, 25x10x12. So my speedo still works...

I put 26" 589's on my 450 honda and at first i hated them but after a few more rides i must say i am very impressed with them. They work awesome in the mud but have yet to try them in the snow.
