Tire stretching is a method to stretch tire which is too small for particular wheel rim.

So, the question is whether tire stretching is safe or not.

People who argued against tire stretching said that each tires is designed specifically to particular rim. The load bearing walls of the tire is made in certain degree from the rim. Tire stretching tends to change the load bearing walls less than the recommended degree. It makes the tire get extra stress and strain and eventually cause quick irregular tire tread wear. Stretched tire also has the risk of getting pop off the rim when it lose tire pressure. A note for you, narrower tire reduce the grip and traction. So, you will not have warranty that the speed rating of stretched tire will be similar with the proper fitted tire.

They believed that the car loads were borne on a bubble of air not the wall of tires. So, it is safe to stretch the tire to certain degrees. Besides, tire stretching makes the car look cool and attract the attentions more to the wheel.
