I call BS on the alarmism about mixed tires. The front and rear are of a different size on these cars anyway. Sure, there may be some incremental change in the balance of how the car behaves and I would like a matched set of all four for extreme conditions, as going to the track - but for street traffic, where at least I never go anywhere near such margins that this would be significant, I'll happily be e.g. replacing worn rear tires before the front tires.

The safety rules for this would be not to mix on the same axle and not to have significantly worse shape tires in the rear than up front so as to avoid surprising oversteer.

edit: oops, didn't note the dates. Sorry for kicking a dead horse.
