Hi Civic Friends!

I have a 2015 Honda Civic LX Sedan CVT Automatic 1.8 Liter 4 cyclinder, live in sunny San Diego, California, and drive 80% highway miles. I am on track to hit 25k miles per year. My car came with stock Firestone Affinity Touring S4 all-season tires w/ specs P195/65R15 89H & 30 PSI cold tire pressure. My primary concerns are minimizing road noise, mpg second, and traction third (so long as the traction is safe enough for normal everyday highway driving).

1. What are the quietest tires available that are still compatible w/ my car?
2. Would you guess these tires give at least the same mpg & traction as the stock tires that came with the vehicle?

What tires do you recommend? Thanks a lot!
