305/30/19s
Need a lil help boys...Monday I'm installing the 305s to the rear stock wheels moving the stock rear 275/35/19 to the front. Tire calculator says diameter difference is 1.4% .. Has anyone done this before any problems with rubbing???
I just calculated the stock tires that came with the car dia difference front to back is 2.1% so computer should be happyer with the 305s rite??? |

No, someone is running 305s. I saw it in the photo forum. I think they're running BC wheels. Maybe you can search on that... he has his offsets and everything in the first post.
But, I believe he is running 265s in the front.

EDIT: Sorry, I think I misread your post and my response wasn't really related to your comment . OP, rubbing aside, 305 is too wide for a 10" stock wheel. However, you likely will not rub on the fender with the conservative stock offset. You may, however, need a spacer to avoid rubbing the strut but that's an easy fix if it is an issue... the real issue is the tire doesn't fit the wheel properly.

The only 305s that I know of that have fit on stock 10" rear wheels are the Mickey Thompsons that TPG Racing used.
I have 295 MPSS rears on mine and they had trouble getting them on, but they are a massive upgrade over stock. I don't think 305 MPSS would have fit. |

I tried 275 on a 9" on my last c63 since the 255 was terrible...It was the limit. On my 997S PDK, the 305 are on 11" wheels. I know for sure that some people put 305 on 10.5" wheels on M5 F10
