Tyres tell a story—and on trailers, the signs of trouble are easy to miss. Here's a quick guide to common wear patterns and what they might be trying to tell you:

Depression Wear (Intermediate)

Appearance: Interior tread ribs worn lower than the others.

Likely Cause: Worn suspension, mismatched tyres, underinflation, or bearing issues.

Solution: Inspect suspension and wheel-end components.

Tyre Usage Advice: Safe to continue using until it's time for retreading.

Diagonal Wear

Appearance: Diagonal flat spots across the tread, repeating.

Likely Cause: Misalignment, bearing issues, mismatched inflation or diameters.

Solution: Fix mechanical alignment and rotate the tyre.

Tyre Usage Advice: Retread if damage is excessive.

Brake Skid Damage

Appearance: One harshly worn spot across the tread, sometimes deep.

Likely Cause: Brake imbalance, new brakes, frozen lines, or harsh braking.

Solution: Inspect and service the brake system.

Tyre Usage Advice: May be repairable—if not, retread or scrap.

Depression Wear (Shoulder)

Appearance: Short, uneven wear on one shoulder.

Likely Cause: Mis-mounting or improper pressure.

Solution: Review mounting and inflation practices.

Tyre Usage Advice: Run to pull point, then retread.

Shoulder Step Wear

Appearance: Edge wear over a longer section of shoulder.

Likely Cause: Camber issues or axle misalignment.

Solution: Realign axle or repair damaged parts.

Tyre Usage Advice: Reverse rotation or retread if needed.

Cupping / Scallop Wear

Appearance: Irregular patches of fast wear around the tyre.

Likely Cause: Inflation mismatch, poor suspension, or light-load high-speed runs.

Solution: Check suspension, air pressure, and dual match.

Tyre Usage Advice: Continue running until pull point—then retread.

Stay alert to early signs of irregular wear.  Timely maintenance helps extend tyre life and ensures safer operation.
