there will be a speed difference:
Specification Sidewall Radius Diameter Circumference Revs/Mile Difference
225/45-17 4.0in 12.5in 25.0in 78.5in 808 0.0%
215/45-17 3.8in 12.3in 24.6in 77.3in 819 -1.4%
the load rating is below what the 9-5 specifies, but many tires people run here are not available in that high of a load rating (most of the most popular ones from Michelin, Continental, etc)... so it may not be a huge concern, at least if it is a good quality tire. The tire radius is kind of small for the 9-5 though, so if the treads are getting low, I'd put a set of 225's on there (I'm assuming yours is pre-2006, after that, they went 235/45-17, from which the 215's are 2.8% off)...
