to my knowlege there isnt a single code they use. i had my touring wheels and track wheels scratched and the nissan bodyshop fixed them. i asked the same question and they said there isnt a uniform code like per say how the car has a KYO.


also the track model wheels seem to be a different shade than lets say the touring 18"s

so unless someone knows more its sort of a trail and error guess until you match it
