Got a 16in schwinn chopper free and it has a flat, no biggy. But after a search of part sites, I turned up nothing. Then an idea came to me at work, run 2 16x1.75 tubes side-by-side and drill 2 holes 180* on the rim. Kinda tough getting it together but it's good to go! I also only put 30psi in each tube, 10psi at a time. Hope this helps anyone else with this oddball tire.
