Hello I am A front end and alignment specialist. Your PS' or pilot sport tires are directional, but you can still cross rotate the to the left and right side(If you have a good tire shop they will dissmount and remount the tire on the wheel). This is the way our guys deal with that. More than likely the prob. is going to be a radial pull. First check air pressure. Road force tech. is the very best. It actually simulates the driving conditions.
