1916 German Protos

Tires were not particularly reliable before, trucks drove on massive tires for a long time, simply unable to make enough strong air-filled tires. In the early years of cars, tires were fragile and punctures were common, and tire changes were difficult as they were often nailed to the rim. While there were alternatives, if you had to avoid the most accident, there were those wheels that had a pair of spiral springs instead of rubber rings. These strange tires sit on a German Protos from 1916, which in all probability is a kind of military vehicle for the army and accessibility was vital.
