Yes, indeed, the Toyo specs for the RR 235/40ZR17 say a minimum of 8.0" wide and 8.5 preferred.

Nevertheless, this is the spec size for the 17x7 front rim in Spec Boxster, and it seemed to work fine. Toyo doesn't make a narrower tire for 17" rims.

Of course, now most people have moved to the square setup--255/40-17 on 17x8.5 all around, which does meet Toyo's requirements.
