I have a Ferrari 360 and I just bought a used set of HRE wheels that were originally built for a 430. They are "used" in the sense that they were bought from someone else, but they are new in the box and never installed. The seller contacted HRE and they guaranteed that they would fit perfectly on my 360.
My problem now is getting the right sized tires for these wheels. They are 19x9 in the front and 20x12 in the rear. I have been asking around and the responses have been all over the board.
Does anyone have a definitive answer on what size tires I need?
Thanks in advance.

 

Very simple, it depends on the tire brand.

Michelin=235/35/19 or 245/35/19 up front, 325/25/20 for the rear.
Pirelli=235/35/19 or 245/35/19 up front, 345/25/20 for the rear.
