This is common on your 987 Boxster. I have a 987 Cayman S, and it does that as well. Other owners of 987s have told me that their cars also do it. If I hadn't known about it before I bought my car, I would've also thought something was wrong.

The 986 (1997 - 2004) cars don't do it, but the 987 (2005 - 2013) car do, at least with most tires. It's because the larger footprint of the larger (18", 19", and 20") tires and the Ackerman steering geometry of the 987 suspension makes the tires want to "grab" the pavement when the tires are at the extremes of the steering angles. ike84 is also partially right.
