Ah the Wheels. I just asked Steve Birchall if he thought anyone might be interested in them.
They are Optional 16" Rotor Design from my 2001 A6 Avant Sport with 215 55 16 Nokian Winter Tyres.
There are ONLY 2 WHEELS but there are 4 of the Tyres.
I think they used the same Wheels on Audi Cabriolets of the same era ? They look the same anyway.
