I'm running the 27" Swamp Lites and I'm liking em pretty well. Little to no wear after 150 miles and they pull good. There's a guy (06 Foreman) that just put 29.5's on a 06 Foreman and he said the only mod he had to do to fit them was bending the front fender support bars. Of course I had to do that to fit my 27's! Might shoot him a message and see how he likes em. I didn't go that big in an attempt to preserve my stock axles. Too many people having too many problems with tires that big on stock's!!
