Uneven Tire Wear: Reading the Warning Before It Blows

Overview

The wear pattern on a tire's surface is like a fingerprint pointing to a specific problem: one edge means bad alignment, the centre means overinflation, and both edges together mean underinflation.

Symptoms

• Wear clearly more visible on only one inner or outer edge
• Wear concentrated in the tread centre while edges stay relatively fine
• Wear on both outer edges while the centre is fine
• Irregular or "feathered" wear patches on part of the tire

Likely causes

• Misaligned wheel angles (camber and toe), especially after hitting a pothole
• Incorrect tire pressure — overinflation causes centre wear, underinflation causes edge wear
• Worn suspension or steering components (ball joints or tie rods)
• Neglecting to rotate tires regularly between axles

Diagnosis & repair steps

1. Check cold pressure against the door-jamb sticker, not the number molded on the tire sidewall
2. Run your hand over the tread feeling for sharp edges or noticeable unevenness
3. Request a wheel alignment check if wear is concentrated on one edge
4. Rotate the tires immediately once you notice a difference, before it worsens

Expected cost

Four-wheel alignment $40–95, inspecting and replacing a worn suspension component or ball joint $53–210 per part, and prematurely worn tires mean early replacement at $80–190 each.

How to prevent it

Check pressure monthly, rotate tires every 5,000-6,000 miles, and get an alignment yearly or after any hard pothole impact.
