Just got a set of 22x11x8 dirt devils for my kids breeze, was tired of pulling him out of the mud, the rear knobby tires were horrible, would just cake up with mud
The tires are wider than my 10" gators on my wolverine, heres a pic link
pictures

 

Did those fit on the oem rim size? looks pretty grippy now.

 

Yes they did, the stock size is 10" wide,hardly any tires in that size.
We went out last night i got my wolverine stuck real bad in the swamp.....black muck.....used my tow strap for the first time, 10 yr old and the breeze pulled me out...thank god, we were riding alone....just wish i had my cam to take that pic...was funny .......LOL

 

I would like to get some paddles for the dunes but I wonder if that would make a difference?
