[Gran Turismo]

For the record, the following are the Alpina OEM 20" rim and Michelin PSS dimensions on the current F10 B5 model:
Front: 8,5 x 20 255/35 ZR20
Rear: 9,5 x 20 285/30 ZR20

Your dimensions appeared somewhat odd to me when reading your other thread, but you already had ordered the tires then...

Regarding the "Ferrari" version of the PSS 285/30 tire:
- Note that the cheaper "non-Ferrari" version is OEM on the Alpina B5, so the unspecified Load Index of this version should be fine on any current F10 model
- The "Ferrari" version appears to be lighter than its sibling with less thread depth than all other "regular" PSS dimensions, so it might wear faster. That one is OEM equipment on the 599 GTO, however on its front wheels!
