Patent, Tubeless
tires
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.

Tubeless tires
are pneumatic tires that do not require a separate inner tube. Unlike

of the metal rim of the wheel.
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. 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
