Oversize tires on 2001 Boxster?

Hi, guys. It is time for new tires for my baby. I currently have the 17" stock "Boxster" wheels on my 2001. The rim widths are 7.0" and 8.5". The tires are Conti SC2s, 205/50 and 255/40. I would like to install Michelin PS2s on the stock wheels. Per the Michelin website the 225/45 and 265/40 look to be good candidates.

I have a couple of questions you can help me with. The 265/40 requires a 9.0" rim width. Will there be a problem with this tire on a 8.5" rim? Has anyone tried this? Any experiences? What is the maximum mismatch in radius or revolutions/mile acceptable before the ABS starts to act-up?

Thanks in advance.
