850R

Hello everybody, I am a new owner of a preowned HS250h Premium. My HS is an amazing vehicle with its futuristic options like the Heads up Display and the collision avoidance systems.The factory 18 inch wheels, unfortunately, have some serious curb damage. I called around and locally, the lowest price for repairing the curb rash was going to set me back about $350 to almost $400 USD. Since the tyres are getting close to replacement, and 225/45/18 tyre selection isn't the greatest, I was wondering if I a set of factory Lexus/Toyota 17 inch wheels would fit my car? With there be issues with my suspension/handling if I make the change to the smaller sized rims? Will there be changes to the vehicle's fuel consumption.

I have seen chrome and paint takeoffs of new Toyota Avalon and ES350 wheels, will they fit on my car?
