Michelin has a PS2 295 30 18 N4 spec for the rear of a Porsche Carrera. This is the same size as the front of an ACR. I was told from a reliable source that this tire works great on and is the original front size on an ACR. I was also told the tread pattern is the same as the rear of a Viper PS2 C1 345 30 19 and they work great together on an ACR. Anybody used this combo? Results?
