Question for the fine pilots on this board.
In the case of DL1457 that blew a tire at take off from ATL it circled long enough to burn/dump fuel for a safer landing.

Why not burn the fuel flying to Portland?
Aside from ATL having more (an perhaps longer runways) what is the reason not to complete the flight?
After all, landing with a blown tire statistically (and to the credit of great pilots) is pretty uneventful, and in the event of problems one place is as bad as the other.
