12,000 miles on my F1 All Season. They never once asked about mileage on the tires.

The sidewall question is mute now. Tires can only be replaced by the same exact size. Next time I will go with a different size on the rear to gain just a bit more sidewall.

The Michelin PS AS-plus tires are ordered. As soon as GY and TR approve the transaction, they will be sent, they are in stock. Shouldn't be a problem since TR recommended them for replacements.
