Is it safe to build Tier 2 Links to your main site?

[Lapua]

The links would be of no use if you get them from irrelevant sources.
Ensure that the links you get are from relevasnt sources.
Buying links is against the advise of Google.
But if you are confident that these links will help you then so be it.
Don't get more than 3 links from a single page is all I have to say.

OP isn't confident on whether the links will help or not. That's why he or she asked.
