Uneven Tire Wear: What the Pattern Means and How to Fix It
The wear pattern tells you the cause: one edge points to alignment, the centre to over-inflation, both edges to under-inflation and cupping to worn shocks. It is safe to drive unless the tread is near the wear bars or cords show.
Can I drive it? Safe to drive
Safe unless the tread is near the wear bars or cords show. Fix the cause before buying new tires.
Typical repair cost
$80-$150 for an alignment, $15-$50 for rotation and balance, $150-$500 per axle for suspension parts.
General US estimates, not quotes. Prices vary by region, vehicle and shop.
If the car also drifts, read car pulls to one side. Alignment is the most likely cause, so see wheel alignment problems. Shaking at highway speed is covered under steering wheel vibration. To narrow down the cause, ask AI Car Mechanic about your exact car.

Frequently Asked Questions
How often should I rotate my tires?
Roughly every 5,000-7,500 miles, or as your manual says.
Why is only one edge worn?
Alignment (camber or toe) is usually out. Worn suspension parts can also cause it.
What causes uneven tire wear on the front tires?
The usual causes are the same for any tire: wheel alignment first, then improper tire pressure and worn suspension components. Check the pressure, then have the alignment checked, and fix the cause before buying new tires.
What are the symptoms of uneven tire wear?
The inner or outer edge of a tire is worn down, the tread shows feathering or scalloping, the steering wheel vibrates at highway speeds, the car pulls to one side or the tires are noisier than before.
