I put on a powerking tire 31" dia. It was about $70 ea. I'm considering going to a 33" snow/mud that is available from Power King also. They are bias tires and 6 or 8 ply. I put them on my 16" original wheels. I used to have a 27.5" dia. tire, and it made a noticable difference. I heard that out west, they like the bias tires and large dia. for some reason. Maybe there are others available. - Scott
