BMW 3-Series (E90 E92) Forum - View Single Post - Tire sidewall question... Who has the facts?

Still confused.. I have always thought that the "30" in a 275/30/19 tire would refer to the thickness of the sidewall. How does the width have any effect on the diameter/aspect ratio?

Thanks for the help I'm trying to learn
