Audi S3 8Y Winter Wheels/Tires (US)

[shoptb1]

I've got a '22 S3 (8Y) on order, and it should arrive sometime later this summer. It has the sport package with the 19" summer tires and wheels, which I understand are extremely low profile. The road conditions here in Colorado are not great, and I foresee issues with this setup, especially in winter. I'd like to have a 18" wheel/tire set for the winters, but the US Audi dealers nor TireRack/Discount Tire have any options for the car yet. Has anyone else investigated this? I imagine that fitment over the brake calipers on the sport package is the difficult part in finding an appropriate package.

Thanks!
