And it is not accounting for the aero penalty of a 225 width versus a 165 or 175. Too, it is not strictly the case in the chart that wider is always the better. There are exceptions due to variation arising from tire design, I was told.

See my car's mod & maintenance thread and my electric bicycle's thread for ongoing projects. I will rebuild Black and Green over decades as parts die, until it becomes a different car of roughly the same shape and color. My minimum fuel economy goal is 55 mpg while averaging posted speed limits. I generally top 60 mpg. See also my Honda manual transmission specs thread.
