Story time. When my parents divorced and I still lived with her, my birth mom started dating this real piece of shit. They broke up and he decided to show up and do exactly what was said here, let the air out of her tires without damaging them. She caught him, called the cops, and they showed up while the two were yelling at each other in the yard. They got him to leave or face trespassing but flat said that it wasn't illegal to let the air out of the tires since no damage was done. They did say that if she had not known about it and had driven the car and damaged the tires it could be a charge if you could prove who did it. That was Georgia in the 1980's so laws may have changed in the meantime.
