Thanks for the info on the tiresize calculator. After researching a little more I can confirm 2010 Aurion ZR wheels fit perfectly albeit with different size tyres.
Stock wheels were 205/55/16 on 6.5 inch rims and the upgrade was 225/45/17 on 7inch rims and still have plenty of room under the guards. The ride is comparable with standard wheel/tyre combo with a little less body roll in the corners.
Overall I am extremely happy with the upgrade.
