Add another rim lock right where the tire pops off the rim bead, if the rim actually has a bead. Guessing it is a steel rim with no bead, guessing you are running a tubed type tire on it.
In my experience there is only one adhesive to safely use in tire applications and that is Fish glue. The up side of Fish glue is it's non-flammable and water soluble and re usable, the down side of Fish glue for your application is that it's water soluble. Fish glue is a fast drying, cold set, highly flexible adhesive largely used in woodworking.
