If you are running the stock rim size, have you noticed any issues with the slightly too-narrow rims with those tires? Do they rollover on the rim when running hard?

Stock 7" rims, and I have run on those rims in 225/45/17:
Sumitomo HTR Z III
Hankook R-S3
Toyo R888
No problems whatsoever and have never had any trouble getting them mounted. The first one out of these was the Hankook which I got from Tire Rack and they confirmed it was an approved size for the Boxster on a 7" wheel.
I just did a quick check on Tire Rack and all 3 of the tires listed above are approved on a 7"-8.5" wheel, with the section with the various tire measurements being made on a tire mounted to a 7.5" wheel.
Each tire brand may be different so that may be why your tire didn't list 7" as an approved wheel width?
