Hopefully i can help..
The specs for that particular car are correct - so no problems as far as i can see with what you have and my data as below..
On an 18"
Front = 225/45 R18 91V
Rear = 225/40 R18 95V
I do hope this helps
The rear sizes are 255/40 not 225/40 is that still OK?
Hi..there..sorry..just noticed that was a miss type? - yes that size 255/40 R18 95V is absolutely fine on the rear axle..apoligies for the mix up there...Rob
