I recently had tyres and the nut was crossthreaded, got my garage to renew etc but since then i have had my kia pullingb to the left, and its a pain. i have had the wheels swapped around, tracking done etc but it still pulls to the left. i have bumped the right side wheel against the kerb offsetting something and this has helped enourmously. my kia also wanders now as if the tyres are not grippng the road properly the steering like " Floats ", am waiting for sunnier days to sort problem out completely until then its very frustrating and am thinking of selling the car because of this problem
