  1. ATTENTION: http/https Bug Fix! Most of us have been experiencing problems staying logged in as we navigate the site. That is simply the result of links varying between http and https, which each require different logons. To resolve we are going to force https starting sometime Wednesday. However, you may have problems accessing FerrariChat until after you log out, clear cookies/browser cache, and log back on. Keep in mind my email is admin@ferrarichat.com if you do have access problems after Wednesday. Thanks!

    Those are not standard 612 rear size tires (285/35 20 OEM), so the closest in the 2009 OM is 33 F, 30 R. With the larger rear tires, I would try 33 psi F&R and see what that does for you. All the tire pressures Ferrari recommends are developed empirically by a test driver, so in this case, that is you. Adjust accordingly if you do not like the feel with 33/33 as a baseline.

    I run mine with a higher pressure in the front versus the rear, about 10% difference. I believe that's per Ferrari recommendation and seems to work well although I am on standard 612 challenge wheels with MPSS.
    As an aside I saw my rear tyres get up to 60c whilst on our Italian road trip!
