Following the letter(s) that identify the type of vehicle and/or type of service for which the tire was designed, the three-digit numeric portion identifies the tire's "Section Width" (cross section) in millimeters.

P225/50R16 91S

The 225 indicates this tire is 225 millimeters across from the widest point of its outer sidewall to the widest point of its inner sidewall when mounted and measured on a specified width wheel. This measurement is also referred to as the tire's section width."

Therefore, 285mm - 275mm = 10mm = 1cm = 0.4in = just a little less than half an inch wider. Right? Or am I missing something?
Correct. About half an inch wider with a 285 tire but the diameter will also be a little larger as well! (0.27") Assuming 35 series tire.

But that is fine, as the Nismo comes with this size tire and it's perfectly fine.

Ah, so the diameter will be slightly larger because the fit on the wheel will really be about the same, causing the tire to bubble slightly?

I guess the width diff is minimal. They look good but wanted more
