Let's say an Earth-like terrestrial planet has a rocky moon, and that moon has small rings, probably from pulling apart an asteroid, comet, or something similar. From my personal research, I know it's possible for moons to have rings, but nothing specifically about how they theoretically could affect the tides of a planet.
Would these rings affect the main planet's tides? To be honest, I'm also not sure why the main planet wouldn't just pull the rings away from the moon, but it's an interesting idea, anyway. My only thought to remedy that is perhaps the rings could've been present temporarily in the planet's history, but dispersed later.
