Tire sizes

[ashar56]

I believe the factory tire size for my car is 245 /40 R20 99Y for the front and 265 /40 R20 104Y for the rear. I am looking at all-season tires, however options are a bit limited. In the past, I've had great experience with Continental...while they don't have a size exactly to the OEM specs, they do have 255 /40 R20 101Y for the front and 275 /40 R20 106Y for the rear. Does anyone know if these sizes would be ok?

I can't speak to the Air exactly, but I did +10mm on a Maserati and it worked out great. The tire is only 5mm wider on each side of the wheel, so it's a minimal difference. It'll look slightly "meatier" and have a very slightly larger rolling radius.
