In the process of ordering and mounting new summer tyres I checked my aftermarket set and they are evidently 17JX. What's the "7.5JJ" part of the wheel size? How does it affect things?
The wheels say "ExecutiveLine by Alustar" and it's evidently ATS wheels but that's just about that. There is nothing indicating the offset and I can't find any documentation on the wheels. Just measure the distance with a ruler?
