No they're both 18". However the F355 use 225/18 fronts while the 360 use 215/18 fronts. But that doesn't matter, the 225 can fit the 360 front rims. The stud holes are identical.Enzo250GTO said:Yes I believe this could be done. The 360s wheels are 1inch larger so you would have to get a smaller profile tire to match your current F355's total diameter. I don't remember if the F355 has the sensitve anti-spin software that the 360 has. If it does changing the weight and diameter may cause this to act up and you'll have the warning light on your dash lit up.
