It's a pitty!
I had changed my 17"oem rim to (245F 275R) 20" oem 356 with bridgestone S001 on my 528i F10 and changed back to 17" oem within one week.
The weight of 17"oem rim with RFT 225 weight similar as (245F 275R) 20" 356 with bridgestone S001.
I don't know why my 528I with the new 356 and S001 is much less accerelated (40% less) and difficult( 30% difficult) to brake than with the oem 17" rim.
It's seem loaded with 3 big fat men in my 528i
And very noisy and bummpy. 30% more
There is no reason why I kept this 356 rim accept the outlook. The look is really very beauti. But the performance is really hard to accepted.
So I prefered to keep the orignal 17' oem. It was just changed back today. After that, it is much comfort now .
Do any brother had the similar experience as me ?
