Here is a more detailed list of the different tire wear patterns: 1. Patchy Wear. If the tread wear is looking patchy, you will see dips at various places on the surface. It only wears away in certain areas, with patches revealing themselves through the tire. Patchy tires will cause a bouncing sensation while driving.
