Man, this car has turned out to be the oddest thing ever for tires. First off I can't find anyone that makes stock replacement size F/R other than the Pilot Super Sports; not that that's a problem...great tire.
But here recently, I've really been considering the 6GR R replicas wheels. They're really growing on me. They are factory R specs with size and offset. I'd want to run the stock R sizes on these and darn it wouldn't you know it I can only find those sizes in the Sport Cups. Awesome tire, I know, but not crazy about tearing up a set of Sport Cups on the street every day.
Turning out to be surprising how funky it is trying to get tires for this car. There's literally zero options out there, at least if you want to stick to stock sizes.
I guess this was more venting than a real question.
