You probably have tire wear due to your alignment being out of specifications. To correct this you should have an alignment performed on your vehicle. This won't undo the wear you have but it will prevent more wear from happening in the future. You should have your alignment checked every 12 months, or anytime you may have hit debris in the road or a large pothole.
