@limitedtimeonly flipping A052's probably isn't too much of a falloff as the compound on that tire is remarkably fast from new to the cords. You still are going to lose relative grip though in comparison to the outer half. But yeah, on a camber-limited car, the A052's are a bit of a risk as the real fast guys will wear that outer edge super-quick. I think a remedy to this would be to run a narrower Yokohama. Some many of these tires that wear fast are usually bulged heavily as they are putting as much tire as they can on the wheel they are limited to.
I actually plan on buying a set of A052's for my extra 18x9 wheels. While I'd normally run a265/35-R18 tire, I am actually going to run a 255/35-R18 on it. The 265 A052 is measured at over 10" and thats too much of a bulge on a 9" wheel IMO. While it technically works, I imagine it's rather spongy and sloppy feeling. Plus the 255/35-R18 is almost identical in diameter to the 255/40-R17 that I currently run.
