The tires were replacements for both front and rear.
The rear was nearing it's end of life (BT-023 at 9800 miles) and while the front pilot road still had some life in it (roughly the same mileage, replaced both the stockers at near the same time), I really couldn't stand the tire any longer. The thing tracked horribly when it came to tar'd cracks, gravel, basically anything other than new asphalt. Not bad in the wet though.
I replaced them with RoadTec Z6's. So far, I feel favorably toward them.
