Tire wear patterns refer to tire areas that are affected by uneven wear. Uneven tire wear can indicate alignment issues, suspension problems, incorrect inflation, or bad driving habits. Tire uneven wear can escalate if not addressed properly, posing serious risks to drivers. Learn more about common tire uneven wear patterns and how they can be fixed to extend your tire's life and ensure driving safety.
6 Common Tire Wear Patterns
Six common tire wear patterns include toe, camber, center, edge, patch, and cup wear. Toe and camber tire wear typically develops because of wheel alignment issues. Center and edge wear (both inner or outer tire edges) indicate improper inflation (overinflation for the central wear; underinflation for the edge wear). Patch and cup tire wear usually manifests because of tire unbalance or bent suspension components.
Tire Center Wear: Overinflation
The central worn part of the tire tread indicates that the driver overinflates his tires. With overinflation, the tire's central part comes into contact with the road more than its edges. This accelerates tire wear in the respective area, shortening tire life span and impacting performance (traction decrease, longer braking distance, stiffer ride).
The driver should stick to the manufacturer's recommended tire pressure to avoid central tire wear. Overinflation is typically tempting as the tire rolling resistance drops, optimizing the MPG. However, driving on overinflated tires reduces their service life, making the driver buy new tires sooner. So, the economy is, in fact, a false one.
Toe and Camber Wear: Misalignment
Camber and toe wear suggest alignment issues on the vehicle's steering setup and suspension. Camber wear shows on one side of the tire when viewed from the front as it tilts inward or outward (negative/positive camber). Toe wear manifests through smooth edges on one tire side and sharp edges on the other when looking from a top-down view. This happens because the tire is angled outward or inward (toe-out/toe-in) due to misalignment. Both scenarios need alignment correction.
Tire Edge Wear: Underinflation
Tire edge wear occurs when the tire tread wears more on the outer edges than on the center because of underinflation. Having less pressure than needed, the edges of underinflated tires sag, which increases contact patch with the road. Edge tire wear reduces tire lifespan and affects performance (lower fuel efficiency, poorer handling, longer braking distance).
Cupping Wear: Suspension Issues
Tire cupping looks like a wavy tread wear pattern, with low and high points along the tire tread. Commonly known as scalloping, tire cupping wear can result from suspension issues (damaged struts or shocks), tire imbalance, or incorrect alignment. Cupping tire wear typically comes accompanied by road noise and vibrations, poor handling and stability, and a reduced lifespan.
Patchy Tire Wear: Rotation or Suspension Issues
Patchy or diagonal wear along tire circumference shows as inconsistent wear spots, indicating suspension (worn or damaged components), rotation (falling to rotate tires), balance (lack of tire balancing), or driving habits (for example, hard braking) issues. Patchy tire wear affects driving performance with compromised grip, poor handling, and low ride quality.
Tire Uneven Wear: FAQs
Why Does the Tire Tread Wear Unevenly?
Several factors lead to uneven tire wear: incorrect tire pressure, lack of alignment and rotation, suspension issues, wheel imbalance, or bad driving habits. To regulate tire wear, consider adjusting pressure, rotating timely, balancing properly, and aligning wheels regularly. Learn more about how to solve tire wear issues, as recommended by Michelin.
Is It Safe To Drive With Uneven Tire Wear?
No, driving on unevenly worn tires is fully unsafe because it affects handling, grip, traction, braking distance, and vehicle ride quality.
How Do You Read Tire Wear?
To read tire tread wear, consider the following steps: inspect the tire read surface (check for signs of uneven wear), use a tread depth gauge (consider checking tread depth on different tread areas), examine the tread edges, use the Penny Test, and monitor tread wear indicators. All these steps help in evaluating the degree of tire tread wear and determine their unevenness level.
