similar problems in UK
Hi
I had a similar problem in the UK. You might find therefore some alternative ideas in the month old thread "Winter/snow tyres". There are specialist wheel/tyre shops for alloys in the UK as they are very popular, but steel rims are hard to find. I suspect Italy is similar to the UK in this respect.
Audi recommend an unpopular wheel size that is particularly hard to obtain from anyone else, so don't rule out alternative wheel sizes to fit your choice of tyre - but do get a specialist to confirm that any proposed alternative will be acceptable. I have done a couple of thousand safe miles on my Michelin Alpines now, but I wont know if they make driving the A2 on snow possible until we have some more. Having tried it once, I would NEVER AGAIN drive an A2 in snow with standard road tyres. It has no grip at all, presumably because of the light weight.
