The other factor that is making me think (possibly foolishly) this will all be fine is big coaches go to this resort to drop off clients with luggage etc etc so I am (naively??) assuming the road will be clear apart from possibly a dusting of snow - exactly as you describe above.
So buy snow tyres!!
I haven’t been skiing for 10 years. Never driven before. My kids have never been before. I hope that we will go again but it’s possible we won’t. Hence my resistance to buy a set of wheels and snow tyres. Otherwise I would definitely.
So buy all season tyres!!
You may be the perfect customer for all-season tires. You usually drive in the UK where there is little snow, but relatively much rain. You are now going to winter sports, and there you really need tires that can handle snow.
All-season tires offer the best of both worlds (imho). I've been driving my California from the start with factory fitted Continental Vancontact 4 season tires, and I'm very happy with their performance, both in summer as in winter conditions.
Good all-season tires may not be as good as the best summer tires or the best winter tires, but they are certainly as good as average summer or winter tires, and you can drive them anywhere, all year round...
In any case, they are much better than summer tires in the snow, with or without a snow chain. Something that is an absolute "no-go".
