A paL of mine has a small KTM dealership , I order some parts from him for my 2 CR125,s haha. I think the big 4 or 5 , tracks the sales of parts more than anything. Since that,s where they make all there money . Everything is tracked now, hell I have a twic card- transportation,workers,indentify,card, that has a chip in it. To track me everywhere I go, the card is for going into ports,etc. It,s just another gov. money maker. Diesel fuel is tracked big time to have real time, on the nations economy. To see what parts of the country, are hot, moving goods, then they study everything including tire purchases. At 4,800.00 for drive wheels alone, that says the owner operator is making money, which most are living off there credit cards, using mis matching used tires.
