Widest FRONT tire on a '66 Dart

Its a daily driver, 4 door dart. Im looking at just some stock 15x6"(or is it 6.5") steelies. Wanting to go as wide as possible to improve stability,especially around corners. The 185/70/13's leave much to be desired.

Car will be BBP, swapping a 73-76 A body disc set up on it. Its a slant six,but future holds either a turbo /6, or a turbo sb.
