Longbox55,

You are correct, 22.5 tubeless wheels and tires were "standard" equipment starting in 1956, however many new trucks were still ordered with the 20" tube type tires. Many owners were not ready to switch over due to the availability of tube tires (that's what they had on the rest of the fleet). The 22.5 six lug are a lot harder to find than the 20" six lug.
