The new 18-inch tires were designed from the ground-up, with every element of the tire drawn from a clean sheet of paper: from the profile, to the structure, to the compounds. The design process took in more than 10,000 hours of indoor testing, more than 5000 hours of simulation, and more than 70 prototypes developed virtually, to eventually create 30 different specifications that were tested by nearly all the teams over more than 20,000 kilometres.
Formula One tyres - Wikipedia
https://en.wikipedia.org/wiki/Formula_One_tyresDuring the 1950s and 1960s, Formula One tyres were supplied by Dunlop, Englebert, Firestone, Continental and Goodyear. In 1958, Dunlop introduced its R5 racing tyre, replacing the cotton fabric of the earlier R1 to R4 tyres with nylon fabric, allowing for a reported 12 lb reduction in tyre weight. During the 1960s, Dunlop introduced improved nylon casings, reduced aspect ratio, significantly increased tyre width, and the use of synthetic rubber.
