Power steering hard line

What are the right tires? Right now, (half way through the conversion to manual) I still have my power steering box, but no pump. I have to muscle the **** out of it in the parking lot, so no coffee at low speeds.
Ummmmm.... if you still have the power steering box, no tires will get ya out of that hard steering, it will be a bear to turn. you have to have the manual steering box installed.
