Oof! This happened to my partner once. She drove home on it too without realizing what the tire low warning light on her dashboard meant. Unfortunately it permanently bent a part in the suspension. Forget what it was. The alignment was a nightmare. After we replaced the tire we discovered the rim was torn open too. So after the rim and tire were replaced I took a drive around the lot and found the steering wheel was off center by a good 30-40 degrees. The mechanic worked hard to get the alignment back as close as they could but it was permanent damage. I hope none of this happens to your car...
