Wheel Alignment vs Balancing: Which Does Your Car Need?
If your car pulls to one side, the steering wheel sits off-centre or the tyres wear unevenly, ask for an alignment check. If the steering wheel or body vibrates at certain road speeds, wheel balancing is the more likely starting point. These services solve different problems, although a pothole strike can create both.
Alignment and balancing are not the same
Wheel alignment adjusts wheel angles to the vehicle manufacturers specification so the car tracks correctly and tyres contact the road as intended. Wheel balancing corrects uneven weight around each tyre-and-wheel assembly using a balancing machine and small weights.
Neither repairs a bent rim, damaged tyre, worn suspension joint or failing wheel bearing. A reputable fitment centre should inspect these items instead of treating every vibration as a balance problem.
Signs you may need alignment
- The car needs constant steering correction on a reasonably flat road.
- The steering wheel is crooked while travelling straight.
- Tyres show one-sided or feathered wear.
- The symptoms began after a hard pothole or kerb impact.
Road camber and wind can cause mild drift. Unequal tyre pressure, brake drag and suspension damage can also cause pulling, so diagnosis should include more than an alignment machine.
Signs you may need balancing
- Vibration appears or becomes stronger in a particular speed range.
- Vibration started after tyre fitting, rotation or puncture repair.
- A balancing weight has detached from a rim.
Never replace a missing weight by guesswork. The complete assembly must be measured. Tyre deformation, a bent rim, incorrect seating or worn components can mimic imbalance.
When to stop driving
Safety warning: Stop in a safe place and seek roadside or professional help if vibration is severe, steering suddenly changes, a tyre loses pressure, a sidewall bulge appears, a wheel nut may be loose, or you hear grinding or heavy knocking. Do not continue at highway speed to see whether it gets worse.
Owner checks should be limited to visible tyre damage, cold pressures against the door-jamb placard or owners manual, and checking that no wheel nut is visibly missing. Wheel removal, suspension diagnosis and adjustment belong with equipped technicians.
What to ask the fitment centre
- Explain whether the symptom occurs while braking, accelerating, turning or at a particular speed.
- Mention recent pothole impacts, tyre work or collisions.
- Ask for tyre, rim, wheel-nut, steering and suspension checks.
- Request an alignment before-and-after report where available.
- Ask whether the tyre or rim has deformation or run-out.
- For vehicles with driver-assistance systems, ask whether manufacturer-specified calibration is required.
Can you need both?
Yes. A pothole can alter alignment and damage or disturb a wheel-and-tyre assembly. New tyres are normally balanced when fitted; alignment should be measured after uneven wear, pulling, an off-centre steering wheel or a hard impact.
Buying or selling?
During a test drive, note pulling, vibration and steering-wheel position, then obtain an independent inspection. Browse our showroom, review finance options, or request a trade-in assessment.

Quick questions
Does balancing fix pulling?
Usually not. Pulling more commonly points to alignment, pressure differences, tyre condition, brake drag or steering and suspension issues.
Does alignment stop vibration?
Not reliably. Speed-related vibration more often starts with tyre condition, wheel balance, rim condition and suspension checks.
Should alignment be checked after a pothole?
Yes if the car pulls, the steering wheel is off-centre, tyre wear changes or the impact was hard. Inspect the tyre and rim immediately.
