I was going to post this in technical but I figure that more people that just F owners would have valuable input. I just got a set of new magnesium Speedline challenge wheels for my 355 and I am going to put new tires on them. I am currently using the Goodyear Fiorano F1's on the stock wheels and I don't like them for the fact that they kick up a ton of road gravel and debris. I am thinking of going with the Bridgestone S-03's. The car will see street use: back roads and mountain roads as well as some highway. I do not take the Ferrari to the track as I have other toys better suited to track use. These are some light wheels so I would prefer not to use heavier tires like Pilot Sport Cups. Any feedback would be greatly appreciated.
