Does anyone run a winter setup?
Opinions pls 
We both use winter tyres.
I have a spare set of 16 inch alloys+tyres for my Mk6 GTD. My wife has tyres only, and gets them changed when necessary - cost £25.
Both methods have their pros and cons. However, I much prefer my wife's method.
I can fit/remove my winter tyres when I want. Though this involves 1.5 hours of heavy lifting. The alloys look crap on the car, but I don't have to worry much about hitting a pot hole on a dark winters night.
My wife has tyre storage bags with handles. She lifts the tyres into her boot. Takes the car to the local fitters. They do the heavy lifting and the tyres get balanced twice a year. The bags keep her and the car clean. The car looks exactly the same. She doesn't have to buy alloys.
People seem to think you need a second set of alloys for winter tyres. You really don't.
