Tire Wear Patterns: What Your Tires Are Telling You

Your tires are the first place that suspension, alignment, and driving habits show their impact. By "reading" your tread wear, you can prevent costly repairs and improve safety.

Common Wear Patterns & Their Causes

1. Wear on Both Outer Edges (Under-Inflation)

If the center of the tread is deep but both shoulders are worn flat, your tires are under-inflated. This causes the tire to collapse inward, putting all the pressure on the sidewalls. This reduces fuel efficiency and generates dangerous heat.

2. Wear in the Center Only (Over-Inflation)

If the middle of your tire is bald but the edges look new, you have too much air pressure. The tire "balloons" out, and only the center contacts the road, reducing traction and comfort.

3. One-Sided Wear (Camber/Alignment Issues)

If the inner or outer edge of the tire wears faster than the rest, your alignment (camber) is off. This is common after suspension modifications or if your vehicle has hit potholes.

4. Cupping or Scalloping (Suspension Issues)

Wavy or "dipped" tread patterns indicate worn shocks or struts. The tire bounces instead of staying in consistent contact with the road, reducing handling and comfort.

5. Feathering (Edge Scuffing)

Feathered edges on the tread indicate slight misalignment or uneven wear. This usually shows up as small ridges you can feel with your hand across the tire surface.

6. Patchy or Spotty Wear

Random bald spots or uneven patches can point to suspension or wheel mounting issues. Check that wheels are balanced and that shocks, struts, and bushings are in good condition.

Tips to Extend Tire Life

• Rotate tires every 8,000–10,000 km (5,000–6,000 miles).
• Check tire pressure monthly and before long trips.
• Do not overload the vehicle beyond manufacturer recommendations.
• Inspect suspension and alignment regularly.
• Replace worn shocks or struts promptly.

Common Tire Wear Myths

Some believe that over-inflating tires improves fuel efficiency. While this can slightly reduce rolling resistance, it causes center tread wear, reduces grip, and makes the ride harsher—so it’s not worth the risk.
