Perhaps but there is more to it than speed. Cornering at normal speeds is improved slightly too.and some of us like larger wheels because of the appearance.To be honest, 17" or 18" wheels on the A2 is like an old lady with running shoes.
As you are saying, the A2 is no race car but there are other reasons for larger wheels.
