Here you go Bob. I use a Sullivan SkyLite 3 1/2" wheel. Remove the plastic rim. Then use a razor or exacto blade to remove the center bead in the tire and fit tire onto the Yellow Aircraft rim. It fits like a glove and looks great. I recommend using CA or Goop to glue on the tire if you're prone to hard braking or side loads. Also, as with all soft rubber if you leave the jet sitting for a long time, turn the tires on a regular basis to prevent creating a flat spot. If it happens, don't worry, you can massage the flat spot out. Good Luck!
