Optional tire sizes for 20" CX-9 wheels?

I just installed Nitto NT420Vs on my wife’s 2018 Signature. Tire size 275-45-R20.
So far like the ride, low noise level, responsive and looks.
 
275 45 20. way better traction and handling. same mpg so far. mines a fwd so alot better grip on from stop with these since i don't have a rear diff for better grip, but it's still a fwd......🦼 View attachment 317797
any noticeable changes in ride comfort? I've read that 275s wouldn't compromise the comfort as much since there is more air volume?.. but at the same time the tire is overall shorter in diameter...I'm considering the same size as well.

Side wall stays the same between 255 50 and 275 45. Same ride comfort
