Bikes don’t turn handlebars all that much. Small movement has big effect. Twitchiness or quick handling is exactly big responses happening from small inputs. If you were moving the handlebars and front wheel a lot you would be a stunt rider and already know about all this.
Clyde Clydeson makes an excellent point. His suggestion will work. And you only have to spend for one tire. In most cases the front fork will clear more tire than the rear.
