There is an edge wear issue with the A3S04 that is not due to the car. The wear is being reported on all sorts of cars: stock MINI, stock Miata, street prepared Miata, street prepared IS300...
However, I think that Randy's initial 20-run debacle must have something to do with the car, as I got more than twice the number of runs on the same size wheel and tire on a heavier car with a softer suspension.
The Kumho 215/40-16 might fit, no? Maybe some of you should write to Kumho and let them know your fitment concerns. They had been planning a 205/45-16 at one point. Maybe this is the same tire, but they've decided to be a little more accurate about their size markings...
