Show evidence for this exact wheel size and offset on my vehicle/year. Exact size+offset builds are observational evidence only — not a universal fit, not the “correct” offset, and not a no-rub guarantee.
3 documented 2010 Audi A4 builds in our database use 20×8.5 ET38 wheels. This is observed use — not a fit confirmation.
