I picked up some steels+winter tyres in germany last month to fit my B8 A4 3.0TDI Quattro.
They have +6mm on them and I paid €100 for the lot. Absolute bargain.
Should be unstoppable if the white stuff hits the problem will be everyone else still on summer tyres, getting stuck/driving at walking pace so they dont end up in a hedge.
Having driven on winter tyres before, i'm excited to try them on the A4. The grip is really reasuring in bad weather and quattro will mean i can have some fun too
The above are et 41 only 2mm difference with a 57mm bore so won't fit a B8, do you want wheels for a B8 as you can get them from tyreleader as well.
If you have a look you could get a set of alloys for a similar price to steel wheels.
