If your tyres are wearing more on the outer edges than across the centre, it usually means your wheel alignment or suspension is not set correctly. This uneven wear reduces tyre life, compromises handling, and can increase stopping distances. An assessment helps identify the cause and prevent premature tyre replacement.

What does it mean if tyres are wearing on the outer edges?

Outer edge wear usually indicates the tyres are making too much contact with the road surface during turns or under load. This is commonly caused by incorrect wheel alignment (toe or camber angles) or worn suspension components.

Common causes of outer edge tyre wear

• Incorrect wheel alignment (too much toe-in)
• Worn or damaged suspension components
• Underinflated tyres increasing sidewall flex
• Aggressive cornering or frequent sharp turns
• Failing shocks or struts causing poor tyre contact

Why do you need to fix this problem quickly?

Driving with unevenly worn tyres reduces grip, especially in wet conditions, and increases the risk of blowouts. Fixing the cause early helps you avoid replacing tyres prematurely and improves overall safety.

How do you know when to get it checked?

You should book an inspection if:

• The outer edges of your tyres are noticeably more worn than the centre
• Your steering feels loose, vague, or pulls to one side
• You experience uneven handling or vibrations
• You haven’t had a wheel alignment in the past 12 months

What happens during an assessment?

A mechanic will:

1. Inspect tyre wear patterns on all four tyres
2. Check tyre pressures and adjust if needed
3. Examine suspension and steering components for wear
4. Measure and adjust wheel alignment angles
5. Recommend tyre replacement if tread depth is too low

How much does it cost to fix?

A standard wheel alignment typically costs $100–$180. If suspension or steering parts need replacing, costs may range from $300–$900+. New tyres may also be required if the tread is already worn down.

Is it unsafe to drive with tyres worn on the outer edges?

Yes. Tyres with uneven wear have reduced traction and may compromise handling, especially in wet conditions. Driving on worn edges increases the risk of tyre failure, so it’s best to have the issue inspected and corrected promptly.
