I think this may be a related question... Is the rim width on the stock Einke wheels the same as the width on the stock BBS MR wheels? In other words, will the 255/40/17 615's work on the Einke wheels as well? I believe the stock Einke wheels are an 8" width. Are the BBS MR wheels 8" as well?
Thanks in advance for the clarification, as I am looking for new tires this spring as well and there seems to be an endless morass of options to wade through
