Need some wheel advice

[Blitz2105]

Hi all, 

New owner here and looking for some help with my wheels/tyres. I live in the very north of bonny Scotland but work in Cambridgeshire so travel a lot. I've just bought my first BMW (320d M Sport GT) and I'm looking to get myself a set of winter tyres. 

I currently have 19' Pirelli P Zero run flats on but am wondering if I am able to put 18' wheels on with the winter tyres instead of the 19s?

I am able to get 18' secondhand alloys (to save on cost) but cannot get used 19', only brand new ones and would really like to avoid spending a grand just on wheels. 

Thanks in advance

Have a look at my posts on the 3 series forum, winter wheels and tyres.

Hope it helps.
