I am sorry guys, was out of the country / no internet access.
Replied to all the PMs hoping to address all questions especially price.
As mentioned in the other post.. I can say that currently the alloys fit the "standard" tires sizes.. i.e. 235 front and 265 back. I guess you can go one or two notches wider but not much beyond. I will try to get the exact alloy sizes but I had bought them to be used as BMW designed the car to operate...
Sorry again for being late in coming back to everybody.
