Good looking wheels mean nothing when you're sliding out of control towards a ditch!
The biggest improvement is the fact that when the weather turns nasty you can make safe progress. Was blown away by the amount of extra grip these offer...
If you choose an alternative Winter wheel/tyre combo I would go for the same 18" wheel sizes as the official BMW package as the skinnier rears wheels/tyres really help with traction.
If you're interested in mine, please drop me a PM...
