What causes a scalloped wear pattern on the tires?
Cupped or scalloped dips appearing around the surface of the tire tread wear could indicate loose, worn or bent suspension parts. Shocks and struts are the most likely culprit because they provide damping force to control tire movement. When the tires move excessively, the scalloped pattern can appear.
What type of tread wear pattern would indicate under inflation?
Tire tread wear in the center of the tread pattern tells you that the inflation patterns are too high. Too much pressure can cause the contact patch to shrink and the center of the tire to carry the entire load. Tire tread wear on the edges of a tire will typically indicate inflation pressures are lower than specified.
What kind of wear pattern does a tire tread have?
This is a special type of wear pattern that causes each tread to wear on a gentle slope or diagonally called feathering. One side of the tread will be sharp and higher, while the other edge will be lower and smooth. Run your hand across the treads to feel the uneven wear of each tread.
What causes a tire to wear irregular patterns?
Air Pressure: Improper air pressure will cause tires to wear in specific patterns according to whether the tire is over-pressured or under-pressured. Balance Issues: Improper balance will cause the tire to spin with a wobble due to unbalanced centrifugal forces.
What does it mean when tire tread is uneven?
This refers to thinner tread in the middle of the tire vs. the outside edges. This means the tire was over-inflated, and allowed the middle portion to have more contact with the road than the outside edges. This refers to thinner tread along both of the outside edges of the tire vs. the center.
What causes uneven toe wear on a tire?
Toe wear is often caused by an alignment problem. This refers to exaggerated inner or outer edge wear (not both edges). “Camber” is the angle of the tire in relation to the ground if you’re looking at the car from the front.
What causes the tread on a tire to wear out?
Here are the most common tread wear patterns and what causes them. Over-inflated Tires. Tire tread wear in the center of the tread pattern tells you that the inflation patterns are too high. Too much pressure can cause the contact patch to shrink and the center of the tire to carry the entire load.
What are the wear patterns on a tire?
Tire Tread Wear Patterns. Outside Edges: Tires that are worn on the outside edges have been underinflated. There is excessive contact with the outer edges of the tire and the road surface as the vehicle travels down the road.
What does tread wear tell you about suspension?
Tire tread wear can tell you a lot about a suspension. Most specifically, it can tell you if the angles, inflation and components are within specification. Here are the most common tread wear patterns and what causes them. Tire tread wear in the center of the tread pattern tells you that the inflation patterns are too high.
Toe wear is often caused by an alignment problem. This refers to exaggerated inner or outer edge wear (not both edges). “Camber” is the angle of the tire in relation to the ground if you’re looking at the car from the front.
