Motor Truck plates were issued to trucks with
solid rubber or solid steel tires. These were typically very heavy
trucks which had been manufactured before pneumatic tires had developed
to the point where they could sustain such heavy loads. Because solid
tires tend to tear up the roadway, these vehicles paid significantly
higher registration fees than did trucks with pneumatic tires. Motor
Truck plates are known to have been issued only from mid-1923 through
the end of 1929. |
