Couple of notes on today's paper. Tubeless tire test success made the Front Page of the NY Times, rubber is a big deal.

Ike drove his in-laws 1912 electric car. Wonder if any Volts or Leafs will be on the roads in 26 years?

Also Homer can you add me to the ping list?

Ike might well have longed for the relatively care-free days of 1938 when he was in North Africa dealing with the French and trying to keep his military operations on track.

You are on the list. Welcome aboard. I should warn you that my daily pings to the class are posting twice, for some reason. I have notified the mods and I don't think it is because of anything I am doing different, but it has been that way for a week or so now.

History

Many patents had been filed covering tubeless tires. Killen Tire applied for a patent in 1928 and was granted GB patent 329955 in the UK in 1930. The Wingfoot Corporation, a subsidiary of Goodyear Tire were granted a patent in South Africa in 1944. Due to technical problems, most of these designs only saw limited production or were abandoned.

BF Goodrich applied for a patent in 1946 and eventually received US patent 2587470 in 1952 in the United States. By 1955 tubeless tires became standard equipment on new cars.[1] BF Goodrich had to defend their patent in court several times, due to the similarities of previous designs. The primary difference between the BF Goodrich design and their predecessors was the usage of butyl rubber, which was more resistant to air leakage than the natural rubber used in the other designs.[2][3]

Evidently the test wasn’t a complete success as it didn’t become practical till after the war.
