Bicycle tyre

In 1892, J. F. Palmer of Chicago, Ill., was granted the first bicycle tyre patent for a self-healing cord tyre design (U.S. No. 476,680). By designing the tread portion of the tyre to operate under compression, any puncture there would tend to close rather than open. It was the B.F. Goodrich Company of Akron, Ohio that began its manufacture the same year. This patent came about one year after the first pneumatic bicycle tyre was patented in the U.S.
