I haven't used spacers, so take this with a grain of salt (or a rock, or a boulder)...
Spacers move the tire mount further away from the vehicle. From a pure mechanical viewpoint, that's more leverage/stress at the mount. Whether it's enough to make an appreciable difference, I don't know.
As far as tire wear, as long as the overal geometry stays the same, it wouldn't think it would make a difference. The question is whether the geometry actually does stay the same.
