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.

The abundance of rubber polymers in pure tire tread (Fig. 2) and the typical sizes of TRWPs found in the environment entail that the TRWPs can be classified as microplastics (MPs), according to both the commonly used terminology (<5 mm in size) and to the more recently recommended size range,, from 1 μm up to 1 mm []. Specifically, TRWPs are classified as primary MPs,, plastic ...

Tire Feathering. Tire feathering is a tire wear pattern when the treads on a tire are rounded or lower on one side and higher with shaper edges on the other. This occurs because the tire is worn down at an angle and is an indicator of a misaligned toe angle. Vehicles are very sensitive to even minor changes in toe angle and a good alignment ...

The vertical roller mill (VRM), including powder separation and crushing subsystems, is used extensively for intermediate crushing of minerals in several industries such as cement, electric power, and chemical. Compression crushing is also the main crushing mechanism in the VRM, but there is also shear force between grinding roller and particles.

Feather Edge Tire Wear. Feathered tire wear refers to the pattern where the edge is smooth on one side and lifts on the other. Among the causes of feathering is excessive positive or negative toe or poor alignment settings. There is also the toeout tire wear, which is quite similar to the feather edge tire damage.

The source of tire retainer pressure is the horizontal component of the interaction between the tire ID and the support pads. Tire retainer wear is therefore always accompanied by wear of the tire ID and the support pads. The wear of the pads will result in a loose tire, leading to high shell ovality and refractory failure. These adverse
