A friend of mine with a 996 runs 255/35/18 in the front, it fits but barely. He is on stock suspension, which I am relatively sure is about the same as ours in the front. He runs 315/30/18 on the back

245/40/18 won't fit in the front of a 986 with the OEM struts (at least on an 8" wheel, maybe a wider wheel would flatten it out more?) - the tire hits the lower spring perch and you would have to run a huge spacer to push it out far enough, to where I don't think it would be safe. Folks with aftermarket coilovers like the PSS9 can run 245/40/18 in the front.
