2 final ratios in SUBARU BRZ

I found out a critically strange description in the newest catalog of SUBARU BRZ, Final gear reduction ratio, 4,100 for 626mm diameter 215/45/17 tire model, 3,727 for 632mm diameter 205/55/16 tire equipped one promptly.

Suppose that the difference of tire diameter might be compensated by different final gear ratio, this is a very natural story with no question, but judging from the printed sentence in the catalog the applications are opposite ways each other, smaller diameter with lower reduction ratio, how come?

The imaginations from the printed number if they are correct ones, there exist some completely different two characters each other on earth!
The printed matter should not be the truth so I conclude.
My opinion on this title here looks as if mine was reinforced by some concrete proof scientifically, yes, based on actual experience.

E-211 Skyline Japan was modified on the motor from L20 to L28, original final gear ratio was 4,110, leading to the result of unbalanced reduction ratio that unstable accelerating reaction, then that was replaced into 3,700 following the ratio of 280 Fairlady Z model with gaining favorable stability on that inconvenient point. Consequently I can say above with some self confidence.

SUBARU stuff promised to reconfirm on this proposal. I'm looking forward to hear the answer from the company.
