RE: Need Kraft wheels........
Dang, really hoping you would have the 3". I was so discouraged when I found that gum ball in the new box. It's hard to imagine how Hayes was able to get it in the box without vulcanizing.
All of my wheels are the regular tires with tread. I never had any streamlines - didn't like 'em.
I had two of the 2.5 inch wheels as mains on a Sig Bonanza that I flew through a tree at about Mach 2 in 1983. The wheels were about all that emerged in one piece. Unfortunately I have misplaced one of them in the ensuing 27 years with time and a house move.
