Did a search, but not much answers.

I have a 2007 530i with sport package (245/40/18). I need to purchase winter tires/wheels from tirerack. I just wanted to know is it better to downsize to 225/50R 17 (is this the correct size for winter?) or should I stay with 245/40/18?

Thanks

I have two sets of winter wheels, one that i use while in town.... 245/45R17 and then i have 235/60R16 that i use when traveling out in the country...

Trust me, Winters in Iceland can get pretty crazy...

Just buy a set of wheels you like, with the size you beleive is comfortable, the 17's are Bridgestone Blizzaks and the 16's are Michelin X-Ice North (spiked)...

I had some Toyos with no spikes in them on the 16's and i found them not to be very good...

How are the conditions where you live ?

My advice is that you just buy whatever you think looks good, and then pick out some tires you like as well...

Sizes are something you just pick out for yourself...

I've changed the tires on my OEM M5 rims, from 285/35R19 & 255/40R19 to 305/30R19 and 275/35R19 and they fit just nice...
