Update on my car pulling problem: I have put my rear wheels in the front and the problem is gone. Previously I only rotated the front tires left / right....that made no difference. Now I just put the rear tires in the front and the front tires in the rear, and the problem is gone. Actually the tires causing problem were brand new dunlops. My rear tires are old ones...Yokohamas. Now when I put old yokohamas in the front, the problem is gone...but no matter what I do with the dunlops, they dont work in the front...and car goes to left. Why is this? Why my new tires, even when rotated left / right, still make the car go left?
