You know something is wrong. But do you ask your mechanic for a wheel alignment or a wheel balance?
These two terms are often used interchangeably. But they are completely different services. One fixes the angle of the wheels. The other fixes the weight of the wheels.
Getting the wrong one won't fix your problem.
Here is how to tell which one you need.
What is Wheel Balancing?
Wheel balancing is about weight distribution.
A tyre and wheel assembly is never perfectly uniform. There might be a slightly heavier spot in the rubber of the tyre. There might be a slight imbalance in the alloy rim.
When you spin that wheel at 100km/h, that tiny weight difference becomes a massive centrifugal force. It causes the wheel to wobble as it spins.
If you need a wheel balance, you will usually feel a vibration. It often starts at a specific speed (e.g., 80km/h and above). It gets worse the faster you go. You feel it "shuddering" through the steering wheel or the seat of the car.
To balance a wheel, we put it on a specialized machine. This spins it and detects exactly where the heavy spot is. We then attach tiny lead weights to the opposite side of the rim to counterbalance it. This ensures the wheel spins perfectly smoothly.
What is Wheel Alignment?
Wheel alignment has nothing to do with the tyre itself. It is about the suspension.
Alignment adjusts the angles at which the wheels are set against the car and the road. Manufacturers specify precise angles to ensure the tyres make optimal contact with the road.
Hitting a pothole, a curb, or just general wear and tear can knock these angles out of spec.
What’s the difference?

Uneven tyre wear?

Steering wheel crooked?
You need a Wheel Alignment.
Why do them together?
We often recommend doing both at the same time. This is critical when you buy new tyres.
If you put brand new tyres on a car with bad alignment, you will ruin the new rubber in a few thousand kilometres. The tyres will scrub and wear unevenly. This costs you money.
Similarly, if you align the wheels but don't balance them, the car will drive straight but still vibrate at highway speeds. This is annoying and wears out your suspension bushes.
Stop the struggle
Don't ignore the shakes or the drift. Both problems damage your tyres and increase your fuel consumption.
If your car doesn't feel planted on the road, bring it into Service Plus Tyre & Auto in Wallan. We can diagnose whether it is a balance issue, an alignment issue, or both. We will get you back to smooth driving.
