Definitely. They're on setting '1'

Also check tire pressures, and set it to stock, or 2-4 above, but don't go too high, cause your tire will bounce too much, and car will fill jittery. But also don't go below stock, because you are running a risk of bending the wheel on potholes.

Definitely check the pressures. Most of the time after installing low profile tires they will pump them up to 40+psi. A good rule of thumb is to add 3psi per plus size. Any time you increase the wheel size, comfort will decline, it's a law of the universe. The sidewalls have to be stiffer as they get shorter, just like springs. That's why almost every tire with a 50 or smaller aspect ratio is at least V-rated
