No manufacturer makes this tire size other than a non-legal slick. According to a tire size calculator, this size would be the exact same diameter as the 275/40/19 tire I have on the GT. You'd think this size would sell like hotcakes for those wanting more rubber out back. Maybe it is a structural thing???
It seems tire makers go from 305 to 325 or even higher. You can find 315/30 tires, but you lose a bit of diameter.
Just curious if anyone might be "in the know".
