Are you suggesting every design starts from scratch. There is no backlog of tread designs and testing to work from. Boy that would be hard to do. You guys are special. Reinventing the tire every time must be pretty tough. So you continually invent the wheel. Bravo.
Nobody said such a thing. Nobody even remotely implied any such thing.
Rather, he was obviously responding to your statement, “With computers every possible permutation of tire design can be done in a week. Tread patterns have been experimented with for decades. There is nothing new.” Are you seriously suggesting that anyone who contests that claim must logically believe that every single design is created entirely from scratch?
