i have 26" zillas on my 06 foreman. If i had to do it all over i would not get them. They are pretty good in the mud but really suck on the trails. sometime i have to put in 4-wheel to climb some trails. If i were you i would get mud sharks. you want the 27 though that way you have 11/4 lugs. my brother has them o his o3 foreman and they are awsome he on his 2nd set
