Stay with the 225/50R16 if you are going to stay with 16" wheels. If you lower the car and they put on a shorter tire it will look like you didn't do anything. The idea of springs is to lower the car and to have less wheel well gap. If you want lower profile tires go with bigger wheels.
thats the same tire size i have on mine now....205/55/16 on the same wheels as well....how much do those springs lower (standard 1.5")?? I thought I might rub...no issues for you? Looks good enough to me!
