What I am looking for is data that shows how a pinched tire compares to a nominal width tire on the same wheel, and whether that will offset the amount of grip lost by losing 20mm off the rear tire with both options being "in spec" on the rear wheel.
Yeah honestly i am not sure. I dont have any hard data of what you are looking for. What i will say is that if you as the driver are more confident with a sharper tire, go that route!

Its why I ran 275s on the type r where others were going with 285s. I liked the sharpness and overall grip of that tire and it worked for me.

I will say as i am in the same boat with weather, its 90% the reason i run the Re71R. It works in all the weather we have here.
