Really? I thought a sports car would come with at last CS tyres, not economy?... Guess it would explain it but seriously? I find it so hard to beleive it comes standard with eco tyres or something similar. There are a few around here, I'll have to take a look at what they are running.
Yes, the GT86/FR-S/BRZ comes with Michelin Primacy GreenX's, same tires you'll find on a Prius. I guess because they wanted to emphasize the tossable nature of the car by giving it low grip tires (and obviously also to improve fuel economy). Throw a set of sticky tires on it and it gets much faster.
