Thank you. I did want to read that. My information was coming from a post by Jan Heine just two weeks old and had presumed that since he is making tires he'd be using current info. In any event the discrepancy here points out how fluid the situation is and how fast things are changing. ETRTO is a stopgap, really wish ISO would speak.
Different width rims do change how the tread faces the pavement. Figuring out all the variables is complex. Complex for the manufacturers and really hard for those who use the product.
