I think it would be interesting to drive identical cars back to back up the same canyon road or track, one with 225 all season runflats all around and the other with performance non-runflats with the 225 F -255 R staggered setup

If the wider rear wheels and tires are specified to decrease oversteer, one could expect the square setup to be pretty tail-happy. It would be interesting to see how differently they handled.
