Glad I asked about the smallest 700x 6 tire, the Airhawk does fit the fork on my 182.

Now debating 850x6 or 800x6 on mains.
Was looking at Goodyears 800x6 and they looked wide fat and nice.
Much better than the Air Tracs I got.

850s look as wide as 800s

Since the weak link is the nose wheel.
How much of a benefit will be 850s over 800s be on the mains.

You might want reach out to Grassstrippilot if he doesn't chime in here. I believe he can answer your question.
