When buying a used car, most buyers focus on the engine, mileage, or interior condition, often overlooking the critical role of tires and suspension. These components directly impact safety, comfort, and overall vehicle performance. Failing to address tire and suspension issues in pre-owned vehicles can lead to significant repair costs and even accidents.
This article highlights the common problems in these areas, how to identify them, and ways to avoid costly mistakes.
1.
Importance of Tires and Suspension
The tires and suspension system work together to ensure smooth handling and ride comfort. Tires provide grip and traction, while the suspension absorbs shocks and maintains stability. Issues with either can compromise:
- Safety: Worn tires or faulty suspension can reduce braking efficiency and increase the risk of skidding.
- Comfort: Uneven wear or damaged components lead to bumpy rides.
- Longevity: Neglecting tire and suspension maintenance accelerates wear and tear on other parts, like the steering and braking systems.

Common Tire Issues
A. Uneven Tire Wear
Uneven tire wear indicates misalignment, improper inflation, or suspension problems. Look for:
- Excessive wear on one side.
- Bald spots or cupping patterns.
B. Worn Tread Depth
The tread provides grip on wet or slippery surfaces. Tires with less than 1.6mm of tread are unsafe and often illegal.
C. Cracks and Bulges
Visible cracks or bulges on the sidewall may result from age, improper inflation, or impact damage. These are warning signs of potential blowouts.
D. Mismatched Tires
Mismatched tires—different brands, sizes, or tread patterns—can affect handling and stability.
E. Improper Inflation
Underinflated or overinflated tires affect fuel efficiency, handling, and tire longevity.

- Common Suspension Issues
A. Worn Shock Absorbers
Shocks absorb bumps and keep the car stable. Signs of wear include:
- Excessive bouncing after hitting a bump.
- Uneven tire wear.
B. Damaged Springs
Broken or sagging springs can lower the car’s height, causing uneven handling and reduced load capacity.
C. Faulty Ball Joints
Ball joints connect suspension components. Worn joints cause clunking noises and affect steering precision.
D. Alignment Problems
Poor alignment leads to uneven tire wear, reduced fuel efficiency, and pulling to one side while driving.

How to Detect Issues
A. Visual Inspection
- Check tire tread depth and sidewalls for damage.
- Look for signs of leaks or rust around suspension components.
B. Test Drive
During a test drive:
- Feel for vibrations, pulling to one side, or excessive bouncing.
- Listen for unusual noises like clunking or squeaking.
C. Professional Inspection
A certified mechanic can identify hidden issues with diagnostic tools, ensuring the tires and suspension are in good condition.
5.
Impact on Costs
Neglecting tire and suspension problems can lead to expensive repairs. For example:
- Replacing worn suspension components costs hundreds to thousands of dollars.
- Tire blowouts or suspension failure can cause accidents, resulting in hefty repair bills.
To avoid such costs, always perform a Revs Check to ensure the car is in good condition. For regional checks, explore Revs Check QLD and Revs Check NSW.

Connection to Other Issues
Tire and suspension problems often indicate broader issues:
- Poor maintenance, as highlighted in “The Risks of Buying a Used Car Without a Service History.”
- Unresolved recalls, discussed in “Understanding Recalls: Are They a Dealbreaker for Used Cars?.”
- Faulty brakes, explained in “Common Brake Issues in Second-Hand Cars.”
7.
Prevention and Maintenance Tips
A. Regular Inspections
- Check tire pressure monthly.
- Inspect suspension components annually or after 20,000 km.
B. Rotate Tires
Rotate tires every 10,000–12,000 km to ensure even wear.
C. Align Wheels
Perform wheel alignment at least once a year or whenever new tires are installed.
D. Replace Worn Parts
Don’t ignore signs of wear. Replace damaged tires or suspension parts promptly.
E. Drive Responsibly
Avoid potholes and rough terrain whenever possible.
Conclusion
Tire and suspension issues in pre-owned vehicles are common but manageable with proper care and attention. By inspecting these components thoroughly and addressing any problems early, you can ensure safety, comfort, and long-term value from your purchase.
Always remember to consult professional mechanics and perform vehicle history checks through services like Revs Check to avoid unexpected surprises. A little diligence upfront can save you from costly repairs down the road.
