Yes,I do think the sidewall could be a little thinner lookswise but for real world driving with potholes and other road surprises I like having that bit of sidewall and the tires have a rim protector built in which helps a little as my wife already has touched a curb twice. The Subi is wearing it's winter wheels right now and it has the same size as the Focus has on it and the look is quite a bit different when I go back to the 18"s with 245/45 size tires.
