He wouldn't save Vulcan by going back. He would just be creating a NEW timeline. Prime Vulcan would still be around. NuVulcan would be dead and NuNuVulcan would be saved.

I'm assuming these are the new time travel rules since Prime Vulcan is around.

edit: Now granted, Spock may not be aware of these new could anyone? Unless there are some differences he may have discovered.
No, the Star Trek universe admits of BOTH branching and single-timeline time-travel.

Slingshot time-travel (and a few other methods) keeps you in the same universe. In Star Trek IV, City on the Edge of Forever, etc., the narrative depends strongly on time travel involving changes to only one timeline.
Ah, but the rules sometimes DO change in-universe and what happened before is swept under the rug. Look at warp speeds - Voyager slowed warp speed down to make crossing the galaxy a 75-year journey despite lots of evidence that such journeys would take a month or so.

There aren't "new rules of time travel" in the Trek universe. Rather, we have discovered that there is at least one additional method to time travel which results in a branching timeline.
NOTE: Mirror Universes are a little bit different since these branches are not created by a temporal incursion, but are rather preexisting timelines which we have occasionally visited (e.g., the Enterprise did not create an evil mirror universe in Mirror Mirror, but accidentally traveled to one).
Just some trivia: In the earliest concepts for what became "In a Mirror, Darkly", William Shatner's Tiberius Kirk would have created the mirror universe as a branching history, after the Tantalus device standed him 150 years in the past.
From Spock's vantage point (which does not include narrative rules from Bob Orci or fanwanks about modified rules of time travel), he has every reason to believe the sling-shot method would work. And he has every reason to attempt it. Why save Earth, but not Vulcan?
If the many in-universe reasons posted so far haven't scratched your itch for a plausible answer (and I think you're REALLY underselling how dangerous Nero was and how easily he could have succeeded) ...
