[urq] Re: TRX Wheel/tire

[Louis-Alain Richard]

Colin, 

Could it be a Mercedes-Benz wheel? Some MB use the 5x112 pattern, but I
_think_ the center bore size is bigger. 

Have you measured the center bore? (Anybody knows the bore centers for
Audi and MB?)
Does MB use the same ball-seat design as VAG do?


On another front, I know that you can buy high quality aftermarket
wheels with just any pattern/ET/center bore. These wheels just looks
like OEM stuff, with steel inserts for the bolt seats, hubcentric and
all the stuff. 
Compomotive is such a manufacturer. 
Maybe Michelin was such a manufacturer in the 80's?
