Opinions on putting 255's on the front to replace 265's?

[Dansblum]

so...I'm at the point I need to get a new set of tires. I have an x90D, it came with continentals, 265/45/20 on the front and 275/45/20 on the rear.

However, it appears some were delivered with 255/45/20 on the front, with the same 275/45/20's on the rear....on the same rims, I believe?

I have I have more options available if I were to go with the 255's on the front - any reasons for or against?
