Alpina B6 rims and tyres fit

[MADEYE]

Hi all,

I have a set of B6 rims arriving soon however I've just realised I have the winter versions!

Size are 8,5J x 20 Front & 9,5J x 20 Rear.
The normal version is 10j x 20 rear.

After researching Alpina seem to fit the same size tyres to the front and rears which seems strange but perhaps this is normal for winter rubber.

So my question is, what size sports tyres can I fit to these rims?

Thanks in advance for the advice.
