Tyre wear

What are the regulations with regard to Tyre Wear?

Bulge:
When there is separtion of the sidewall you will start to see a bulge. This is a serious hazard and the tire should be replaced.
Camber Angle or Toe Angle:
This type of wear is typically caused by bad alignment. This can been seen in a visual inspection. Note that this type of wear is sometimes overlooked when it is located on the inside of the tire.
Chopped:
This type of wear is a chopped pattern. It is usually on the outer edge of the tire. It is typically caused by a lack of tire rotation.
Chunk:
This type of wear can be found on a visual inspection where a chunk of the tire is missing.
Cup:
This type of wear can be found on a visual inspection where you will notice a cup type depression. You will also be able to locate this type of wear by running your hand across the tire.
Tear:
This type of wear could be caused by many different conditions. It can be found by a visual inspection. This type of tire damage typically will expose the tire casing causing greater vulnerability and should be replaced.
Feathered Toe Angle:
This type of tire wear is typically caused by misalignment and can easily be felt by running your hand along the tread.
Worn Outer Edges:
This type of tire wear can be found on a visual inspection where the outer edges of the tire are worn smoothly. This is typically caused by low air pressure.
Worn Center Tread:
This type of tire wear can be found on a visual inspection where the tire tread is worn gradually from the outer edge to the inner tire tread. This is typically caused by over inflated tires and/or improperly sized rims/tires.
Deep Scallop:
Deep Scalloped wear is typically caused by diminishing struts/shocks. Another cause may be tires that are not properly balanced (typically the pattern is tighter).
Tread Separation:
This type of wear is when the tread itself starts to separate. This typically cuases the vehicle to “wobble” at lower speeds and a pull to one side. It has the potential to become a hazard and should be replaced.
