Some people got sick of fixing flats, I guess ?
I am a tad surprised to see non-pneumatic tires on a car instead of the more often seen use on a truck, and even more so in an urban setting. The number on the side of the car in the foreground suggest fleet use.
I suppose the elimination of the possibility of flats and the resultant loss of time would be a benefit to driver and customer.
I still find them on chassis converted to hay wagons
I think one of the best uses for those would be on a tug type conversion tractor or "doodlebug!!
I actually have one of those solid rubber spare tires that came with my barn fresh original 1913 Reo roadster. Although it is a 25" tire on a demountable rim. I have tried to figure out how they installed the solid tire on the rim and have no idea.
My only thought was it was warm and plyable when it was mounted. Today its harder than a dead carp.
Try fixing this flat tire!!
