How does it steer at low speeds. Do you do much low speed maneuvering; parking lots, driveway, etc?
It's a lot of what the driver is used to and find acceptable.
235 and wider up front will start being noticeable difference.
Guy in club has a 4spd 69 Roadrunner with 16:1 and 235/60/15's up front. He didn't complain. But when he changed to power steering, he wished he would have sooner. He lives in suburban LA area too.
