Looks like a waste of time to me it isnt going help if you kerb them. If you want some winters just get some steel or cheap reps when weight isnt as important and you are not going to worry about being damaged by salt or sliding against a kerb if you are unlucky.
My view is that where I live there is only snow on the ground for less than a week and there are no large hills that isnt enough to justify another set of wheels and tyres. My last MK6 with Monza Shadows and Dunlop Sport Maxx worked ok down to -9c last winter (I was driving very slowly). If I kerb a wheel well I will just get it refurbished at £100 a time.
