Tire Wear Pattern Guide
Tire wear patterns reveal a lot about your vehicle's condition. Uneven wear can signal inflation issues, misaligned wheels, or failing suspension components. Catching these problems early saves money on tires and prevents safety issues on the road.
Wear Pattern Summary
| Wear Pattern | Likely Cause | Action |
|---|---|---|
| Center only | Over-inflation | Adjust pressure |
| Both edges | Under-inflation | Inflate to spec |
| One edge | Camber / toe problem | 4-wheel alignment |
| Cupping / scalloping | Worn shocks / imbalance | Shocks + balancing |
| Feathering | Toe angle off | Toe alignment |
When to Check Alignment
Inspect alignment annually and after impacts like potholes, curb strikes, or collisions. Also check when the steering wheel pulls to one side, the car drifts without input, or you notice abnormal tire wear. An alignment check costs $50–$100 and can save you hundreds in tire replacements.
Frequently Asked Questions
A 2-wheel (front only) alignment costs $50–$75; a 4-wheel alignment costs $80–$120 at most shops. If suspension parts need replacement, additional labor and parts costs apply. Many shops include free re-checks within 30 days.
Alignment adjusts the angles of the wheels relative to each other and the road — it fixes pulling, drifting, and uneven wear. Balancing equalizes weight distribution around the wheel/tire assembly — it fixes vibration at highway speeds. They're different services but are often done together.
Fix the underlying cause first, then evaluate the tires. If the tread is worn below 2/32" (1.6mm) on any part, replace immediately. If the tread is still adequate but unevenly worn, you can continue with closer monitoring, but expect reduced performance in rain or emergency braking.
