Tire Rack says that the 16x7.5 Borbet Type T's and the 205/55/Z16 
Dunlop SP8ks are a "guaranteed" fit.

I still don't understand how other folks can stuff a 225/50/R16 on
a 16x7.5 rim and fit it on the CQ.

I am wondering if the Tire Rack Database "assumes" that the 
1990 90 Quattro sedan and the 1990 "90" Coupe Quattro have the same
stock offset.
