Wheel size for the 2004 550 SE?

[mts]

Does anyone know if the rear wheels on the 2004 550 SE are 18 x 9 or 18 x 10? I'm trying to decide whether I can stuff a set of 285/30/18's on them.

Thanks

It should be stamped on the wheel in plain sight.

I'd check with TireRack on tire size. 10x18s have 265/35 ZR 18s as approved size. I didn't check TSBs for any changes.

Didn't realize that and hadn't seen it. I'll take a closer look, thanks.

They are the same size wheels available on any Boxster. 18 x 7.5 front and 18 x 9 rear.
