Andrew is right on the money on the first 2 points, but i would offer an alternate view on the third.
It is quite possible that the tires on your car have already been replaced by 36K. There is a minimum required tread depth for a car to be "certified". My guess is the "pulling" is very typical of the way our cars can track based on road surfaces...part of the price you can pay for wide low profile performance rubber. It could also be as Andrew described, but being a certified car i have to bet that there is at least 50% tread on those tires.
Easy way to tell is grab a tire depth gauge. They are really cheap.
