What causes tread to wear on the outside of a tire?

What causes tread to wear on the outside of a tire?

A lack of rotation can cause this condition. Tread wear on the outer edge of a tire is rare these days, but it does happen. Positive camber, caster and toe can lead to wear on the outer edge. If you see edge wear on one side, check the thrust and setback.

Can a negative camber lead to tire wear?

The camber and caster will become positive in the front, and if the vehicle has an independent rear suspension, the camber will become negative and it will be toed out. This could lead to outside-edge tire tread wear in the front and inside-edge tread wear in the rear.

What does one-sided shoulder tire wear mean?

One-sided shoulder tire wear: This type of irregular tread wear means the inside or outside shoulder rib of the tread is significantly more worn than the other ribs. Also known as camber wear, excessive positive or negative camber often causes this type of wear.

Is it normal to have irregular tread wear?

As tires are used, it is normal for the tread to gradually become shallower and overall tire performance to change. In addition, irregular tread wear may occur for a variety of reasons that may lead you to have to replace a tire sooner rather than later.

Why are the edges of my tires worn down?

This condition shows up on one side of the tire, causing abnormal edge wear in the tread, frequently wearing down to the ply itself. When both edges of the tire are worn down, it indicates underinflated tire pressure. Inside or outside wear can also indicate worn suspension components that have caused wheel misalignment.

What causes wear on the outer edge of the tread?

Positive camber, caster and toe can lead to wear on the outer edge. If you see edge wear on one side, check the thrust and setback. But, it should be noted, the leading cause of outer edge wear on modern vehicles is over-enthusiastic cornering. Inner-edge tire tread wear is the most common tread wear problem most technicians see.

What causes the tread on a tire to be feathered?

Feather edge tire wear: Tires are “feathered” when the tread ribs are worn lower/smoother on one side and higher/sharper on the other. This is often caused by a combination of improper alignment settings, such as excessive toe and caster.

The camber and caster will become positive in the front, and if the vehicle has an independent rear suspension, the camber will become negative and it will be toed out. This could lead to outside-edge tire tread wear in the front and inside-edge tread wear in the rear.
