The real reason for the 17" wheels was to accept the large disc brake rotors on cars. The purpose for 18, 19, and 20-22" wheels to me is not clear. I suppose they need to be larger for trucks but most have small rotors sitting in large wheels. They may also be trying to keep the overall OD the same to not affect the speedometer. Whatever the case, your vehicle will perform the best with the wheel/tire combination your vehicle was designed for.
You probably have a little rotor warpage not noticeable with stock wheels and tires. Well here you go. Screw with the engineering and it is not going to work well. Automotive design has been optimized to save weight and fuel. Mess with it and you could be in trouble.
