It coincides with what this calculator says:

Punch in 175/65 R14 for the first set and 185/60 R15 for the second set.

I run 175/65/R15(stock size) winter tires and 205/45/R16 tires for summer, my speedo is always 100% accurate, I even verified it with GPS.

Might be a 3rd gen thing, I dunno. I have never owned a 2nd gen
