About the 14x7 Alpinas:
Since Alpina doesn´t really make any wheels themselves, they were a commissioning job. The original Alpina 14x7 wheels were in fact made by FPS.
Later the very same wheels became available via BMW, still made by FPS. Called something like "SPECIAL ACCESSORIES
LIGHT ALLOY RIM", part # 36111117425.
In fact you can still buy them from your local BMW dealer (and for a reasonable price) or from Walloth and Nesh. I believe a complete set is around 1000 Euros. Including bolts and centers.

The only real difference between the "real" Alpina 14inchers and the ones you can buy at the BMW dealer is in a small Alpina Logo cast into the center of the wheel.
Funny how anything with an Alpina logo demands such a premium (yes, I agree, the cars are great, but it´s engineering, not religion...)
In the late 70s and early 80s the design was also copied by many other makers such as OZ and ATS. Some of them look very very similar to the Alpina. I believe Orangener is currently selling a set made by OZ that is more or less identical.
So if your cool with a "fake", the FPS Alpina style 14x7 ET 10 is one of the few wheels still available new, at a reasonable price, looks great and suits the Coupe very well. Aesthetically as well as technically.
Also, pretty decent rubber is available in the original 195/70 VR14 format, at least in Europe.
Fulda makes the Carrat Assuro

and Vredestein the Sprint classic

I paid about 100 Euros per tire for the Fulda and it´s a pretty good and very durable tire. Maybe it would make sense to have a set shipped to the new world.
