Depending on the Potenza you are talking about, the front 225/50-17 have load index values that are below the recommended minimum load index for a Q45 (the values for the various Potenza models range from 93 to 94) and the rears are okay at 95 or 96.
Please switch to 245/45-17 with a load index of 95 or preferably mugh higher! The wheels can handle the larger size without issue!
I had the same width and offset G35 rims on my 1995 Q45. Not as nice as these, but not bad at all!
