You know, mine does the same thing, except it pulls slightly to the left.

I got my Hankook V12's put on, and then got an alignment at a Sears near my house.

The guys at Sears told me that because the Hankooks are a directional tire, it was causing my car to pull slightly to the left. He told me to have them taken off and put back on, and that the tire shop should be able to correct the problem.

I never did this, because it was way too much of a pain in the @$$, but.. I guess it's always an option.

No idea if that guy was messing with me though.
