I´m thinking F1 wheels / tires. Huge sidewalls / tire flex, tire sticking to the asphalt better??????
I was talking about tires with BMW factory racing driver Stian Sorli at BMW driver training for 2 years ago. He said it is much better grip with 19 "than 20". But we ordinary drivers maybe not notice a difference?
