I just got a set of "A4 Sport" 16" alu wheels off Audi A4 for my Eurovan. The Eurovan uses a larger (19mm) bolt and higher tightening torque for its original wheels. I got proper 17 mm bolts but don't know the torque required for the new wheels. Help will be greatly appreciated (don't want to overtighten). TIA Radek 91 V8Q 5-sp.
