The two pictured are Firestone RH-5° widow makers. Please find replacements. The best replacement is the 22.5” that is the tubeless replacement for the 20” tube type. I know of at least one available set, perhaps two. They will not be cheap. The narrowest tire available today is the 9R22.5” that is the equal of the tube type 8.25”-20”.

I think I also know of a set of the 19.5” tubeless wheels. These would be much less costly than the 22.5s.

The safer locking side ring 20” wheels are the other option and can still be found in old yards, but living in MA you would have to watch for rust damage from decades sitting in rural yards. Private message me if you want contact info for the guys having the 19.5s and 22.5s. Stu
