I generally use 195-65-15 which I can get a vr speed rating in---the front is where most of the braking is done and I want a decent width tire--they still look in size for big and little plus have high performance engineered into them for speed/traction/braking
Its harder to find rears that look good in big/little size that have speed ratings and I will probably be using 17s from now on for a while
