I wonder if this would be a better setup?

for what wheels?
-GP-

For 18 in. wheels.

Good luck in trying find these 2 sizes in matching brands that are decent enough to not worry about...

I just put on a set of Nismo wheels for an Altima (Rays 57F) and the only combination i could find is a 225/45 and 245/45

if you go this route, you have lots of options as this is the combo used on coupes with 18" wheels.

Check out the Dunlop Direzza DZ101. Sticky a$$ tires that are quiet. They have a treadwear of 300. They are max performance tires.
