You guys are killing me with the chat. If your still running 30"'s or 31"'s, your not looking for the gnarly trails were deflation and added traction and major clearance are a concern. Although without the bigger tires, it might be a traverse expedition to proclaim a victory. When it is time for you to get board of those trips to the scenic trails and get serious about crawling or expedition on different terrain, then I would think bigger tires and on board air.
It all boils down to different strokes for different folks.
If the time comes, then go with it.
I personally would not run the combo listed prior, it seems unstable. I think an ORV needs to be on at least a 8" or better. And the stock 30"'s look good, but I like at least a 33". A clearance issue! <img src="/forums/images/graemlins/kewl.gif" alt="" />
