When I first bought my car, it had a slight pull to the right, but I figured it was just out of alignment. I did an alignment, and everything was in spec, but it still pulled to the right. Later, I got diffrent wheels (rota's with potenza so3's), and without any other adjustments (alignment) the car tracked perfectly straight. During the winter, I had a diffrent set of wheels, (teg fat fives) with all seasons, and the car still tracked perfectly. In the past few months, my potenza's have been getting pretty worn (tons of drag racing, autocross, road course) and also I flat spotted one of them last week, so I decided to put my stock wheels back on. As soon as I put them on, the pull is back. I don't understand it. All four tires are the exact same tire, all have the exact same amount of where, all the same pressure. What could it be? Could it be the tire? Could the wheel be at fult.
