Malesbaca.com – Uneven tire wear on one side is often a sign of damage in your car’s suspension system. When this happens, the tire wears out only on the inner or outer edge, rather than evenly across the surface. This condition not only shortens the lifespan of your tires but also puts your driving safety at risk.
So, what are the common causes of this issue? Here’s the full explanation.
Common Causes of Uneven Tire Wear on One Side
Ideally, car tires should wear down evenly. If you’re noticing wear only on one side, it’s likely due to faulty components or incorrect suspension alignment. Here are some common causes:
1. Misaligned Wheel Position (Incorrect Camber Angle)
When a wheel is not vertically aligned—commonly referred to as incorrect camber—it becomes the main culprit behind uneven tire wear. If the camber angle tilts excessively inward or outward, the tire won’t make uniform contact with the road surface.
2. Damaged Ball Joint or Control Arm Bushing
Ball joints and control arm bushings connect and stabilize the wheels with the car’s body. When these parts wear out or become loose, they cause instability in the wheel position, leading to excessive pressure on one side of the tire.
3. Worn Tie Rod or Rack End
Tie rods and rack ends guide your wheels when you turn the steering wheel. When these components wear out, the wheel angles can shift abnormally during motion, causing the tire to wear more on one edge.
4. Improper Wheel Alignment (Spooring)
Incorrect wheel alignment that doesn’t match manufacturer specifications can cause misaligned wheels. This misalignment affects the weight distribution across tires and leads to accelerated wear on one side.
5. Weak or Unbalanced Suspension
A weakened or poorly functioning suspension results in uneven load distribution, especially on bumpy roads. This uneven pressure causes one side of the tire to wear out faster than the other.
How to Fix Uneven Tire Wear
To avoid further damage and maintain driving safety, consider the following solutions:
1. Perform Regular Wheel Alignment (Spooring)
Wheel alignment is crucial, especially after hitting potholes or curbs. Proper alignment restores your wheels to their ideal angles. You can also read this guide on how to align wheels using a string and tape measure.
2. Inspect and Replace Suspension Components
If tie rods, ball joints, or other suspension parts are damaged, replace them immediately. You can check for wear by jacking up the car chassis until the wheels hang freely, then wiggling the wheel vertically and horizontally to detect looseness.

3. Rotate Tires Regularly
Tire rotation every 10,000 km helps even out the wear on all tires. This prevents one tire from wearing out faster than the others.

Conclusion
Uneven tire wear on one side isn’t just a minor issue—it indicates problems in your vehicle’s suspension system or misaligned wheels. Routine maintenance like wheel alignment, tire rotation, and suspension inspections are essential for safe and comfortable driving.
