I ran a rear tire on the front of a bike once. Wasn't good! The bike was really heavy to steer, and when it did turn, it wanted to drop.It was very twitchy too Some tires are designed for both front, and rear use, and you must follow the installation arrows. If the tire is not designed for front use, do not use it as such. That tire is not designed for the steering, braking, or straight line stability that a front tire needs. A rear only tire on the front, with the shifter you want could very well end up in road rash. Be careful
