| Steering-wheel vibration that becomes noticeable at medium or high road speeds |
Wheel or tyre imbalance; a damaged or out-of-round tyre is also possible |
Dynamic tyre balancing |
Wheel weights, rim runout, tyre uniformity, tread or sidewall damage, and correct wheel mounting |
High |
Choose a service that balances the complete wheel assembly and provides a before-and-after result |
| Vehicle pulls consistently to the left or right on a reasonably flat road |
Wheel alignment, tyre pressure, tyre conicity, or a brake that is not releasing correctly |
Four-wheel alignment check and adjustment where applicable |
Front and rear alignment angles, tyre pressures, suspension components, and brake drag |
High |
Select a provider that measures all applicable axles instead of adjusting only the front wheels |
| Steering wheel is off-centre while the vehicle travels straight |
Alignment angles or an incorrectly centred steering wheel |
Alignment measurement with steering-wheel centring |
Toe settings, thrust angle, steering-centre position, and suspension or steering play |
High |
Ask for a printed or digital alignment report showing measured and adjusted values |
| Uneven tread wear across one shoulder of a tyre |
Incorrect alignment, underinflation, overinflation, or worn suspension parts |
Alignment inspection plus tyre-pressure and suspension check |
Toe and camber, inflation history, ball joints, bushes, dampers, and wheel bearing condition |
Urgent |
Use a provider that checks the cause of the wear before recommending replacement tyres |
| Cupping, scalloping, or repeated high-and-low tread patches |
Wheel imbalance, worn dampers, loose suspension parts, or alignment problems |
Balance and alignment assessment with suspension inspection |
Tread pattern, wheel balance, damper performance, wheel bearings, and suspension joints |
Urgent |
Avoid a balance-only service if the tyre shows irregular wear or the vehicle feels unstable |
| Vehicle feels unstable, wanders, or requires constant steering correction |
Alignment, tyre condition, steering components, or suspension wear |
Full steering, suspension, tyre, and alignment inspection |
Tyre pressure, sidewalls, steering linkage, suspension joints, wheel bearings, and alignment readings |
Urgent |
Choose a workshop that can diagnose mechanical faults rather than offering alignment alone |
| Vibration is felt mainly through the seat or vehicle floor |
Rear-wheel imbalance, rear tyre damage, or rear suspension issues |
Balance all wheels and inspect rear tyres and suspension |
Rear wheel balance, rim condition, tyre uniformity, and suspension mounting points |
High |
Confirm that all four wheels are checked, not only the wheels connected to the steering axle |
| Symptoms begin after hitting a pothole, kerb, or road debris |
Bent rim, shifted alignment, tyre damage, or suspension damage |
Safety inspection followed by balancing or alignment as indicated |
Bulges, cuts, air loss, rim deformation, suspension damage, and alignment readings |
Urgent |
Do not rely on an alignment adjustment if the rim or tyre has structural damage |
| Vehicle has no obvious symptom, but tyres were removed, rotated, or repaired |
Possible balance change or incorrect wheel installation |
Balance check; alignment only if wear, pull, or steering changes are present |
Wheel fastening, bead seating, valve condition, balance weights, and tyre pressure |
Routine |
Choose a service that verifies torque and pressure after installation |
| New tyres are fitted and the vehicle has not been aligned recently |
Existing alignment condition and suspension wear |
Mandatory balancing; alignment check recommended when symptoms or uneven wear exist |
Balance of each wheel, tread wear pattern, steering response, and alignment measurements |
Routine |
Prefer a provider that separates required work from optional checks and explains the findings |
