Hi Steve,
CC has the only STC for 26" Goodyears that I know of. They also now have a STC for 8.50X6 tires, which are almost as big as 26" Goodyears. Bushwheels are now also STC'ed and can be had with harder compond for occasional pavement use. The Goodyears have a lot more wearing rubber though. Bushwheels have little rubber for wear to keep them light, and flexable. 26" Bushwheels are also bigger than 26" Goodyears. I have had 26" and 29" Bushwheels and love them. If I have to land at a "real" airport, I land along side or short of the big paved runways. Even tower controlled airports will sometimes let you do this if you ask real nice, and these large government funded facilities typically keep the edges of their runways groomed better than any back country strips. Tire selection can be a heated debate amoung Cub Drivers, but I believe you either need big tires, or you don't. Most Cubs don't. Their owners just do not venture away from airports enough, and if they have them it is just for "looks", and the cheap tires are fine for them. But for anyone who wishes to land their Cub where no one has landed a plane before and explore the real limits of their machine, tires are not a place to skimp. They earn their keep when you misjudge the softness or roughness of your intended landing site and they let you roll away unscaved, hopefully a little smarter. The money saved on tires will not seem important when the Cub is on it's nose or back in the mud or snow. Consider getting real tundra tires if you intend on using them for their intended porpose, and keeping a set of small tires mounted on spare wheels for pavement use. All this said, the 8.50X6 or Goodyear 26" would be good general use tires for the occasional off airport landing if the pilot is careful. And crosswind landings on pavement are a lot more exciting the larger, and softer the tires get. It's tough to get the best of both worlds with one set of tires. Also, I recently installed a set of retreaded 8.50X6 from Dresser that were much cheaper and looked just as good as new. These are what I would use if operating from pavement alot. Just food for thought.
