A classic example: When Alec Issigonis designed the Mini in the 1950s, he wanted very small wheels. "Ten-inch (254 mm) wheels were specified, so new tyres had to be developed, the initial contract going to Dunlop. Issigonis went to Dunlop stating that he wanted even smaller, 8 in (203 mm) wheels (even though he had already settled on ten-inch). An agreement was made on the ten-inch size, after Dunlop rejected the eight-inch (203 mm) proposition."
