I've been running Mayrun 215/45zr17's since I bought the car. These are what came with the car so it's all I've known.
My major complaint has always been road noise and body roll. I thought the body roll was suspension related.
I just put a new set of Nitto Motivos and man, I am impressed so far. Body roll is way better. Braking and acceleration are noticeably better.
Happy thus far. Excited to see how gas mileage is effected.
