Would it  be beneficial for the serps  to focus your link building campaign for just "used tires"

No, varied anchor texts are the way to go, just make sure you have "used tires" in that order.

"used tires"

"keyword used tires"

"used tires keyword"

"keyword used tires keyword"

Also internal linking on your site should have proper anchor texts as well. I would concentrate on that first, and stay away from paid linking.
