I am not so sure you'll get anything out of these tires. Especially, with the stock size wheels. If you really want to change your tire sizes, you should consider 235/40 and 295/35 with 8" and 10.5" Challenge wheels. |

Of course Mitch is just using the tire numbers... each brand/model of tire will have varying actual diameters for the same tire numbers... check the actual diameters via manufacturer website or TireRack.
However, from Mitch's math, you can see that you are likely making the rear diameter closer to the front diameter... as you do so, you will make the ASR kick in a little quicker. May or may not be a problem. Also, you may result in your odometer showing miles on your car a little more quickly... something almost nobody but a Ferrari owner would care about.
I have Kumho ECSTA V700s on my 360 right now... with sizes roughly what you are asking about... the rear diameter is actually less than the front in that case. The ASR will sometimes kick in when just mildly accelerating. I just click it off... a bit annoying, but not too big a deal.
Also, the rear tire doesn't fill the wheel well very well... some may find that less attractive... but I don't choose tires based on looks.

295/32 has a rolling radius of 26.1"
275/40 has a rolling radius of 26.6"
This combination will reduce the rear by 0.25" ride height.
225/45 has a rolling radius of 25.8"
215/45 has a rolling radius of 25.6"
This combination will raise the nose by 0.1" |
