As each post goes live, be sure to update the tour page with live links. As mentioned before, promote the tour stops on your blog and be sure to mention them throughout your platform with Twitter, FB, etc. and use the hash tag.
Just don't go link crazy. No one likes to feel like their being spammed with promotion links. Focus on what you are offering readers. Which tweet link would you click on?

I think this is a pretty clear choice. Remember that readers don't tune in to blog tours, they tune in to content. Promote the content and you're much more likely to drive traffic to your tour stop.
