Note where it rubs, have a hammer ready and a source of heat, a Heat gun works best but can certainly be done with a Torch, just be careful to heat not melt, Anyways, you heat until if gets soft and take the hammer and push it back with the hammer. (The end of hammer, hold it by handle) Keep holding it until it cools, this will make it stay where you put it. Heat some more and do all of the area, let it cool each time.
When you are done. You may want to drill a hole and put a screw in it. If you do, put silicone on the screw and into the hole before you insert it.
That should take care of it. By the way the alignment will be off since you got new tires.
