I have an Audi A4 B6 1.8T.
Hub size should be 57 milimeters according to the internet: https://www.wheel-size.com/size/audi/a4/b6-2000-2006/eudm/
My current wheels are 7.5Jx16, ET45. My new wheels are 7.5J17, ET43.
However my new wheels won't fit on the hub! It seems like the hub is too big for my wheels. I've tried to measure the diameter of BOTH wheels and it is roughly around 5.5-6.0 centimeters.
What's up? Do I need to like hammer them in place? Or do I need adapters?
TLDR, the hub size of the CAR is too BIG for my NEW wheels. But fits easily on my old ones. Despite the fact that my (innacurate) ruler measurements put them all in the 5.5-6.0 centimeters range, and therefore I think they ought to be 57mm as is spec.
