Wheel balancing and wheel alignment are not the same thing
8 min readBy Wheel Fit
The short answer: balancing corrects weight distribution around a wheel and cures vibration. Alignment corrects the angles the wheels sit at and cures pulling and uneven wear. They are unrelated jobs.
Wheel balancing
No tyre and wheel assembly is perfectly even in weight. Spun at speed, a heavy spot creates a vibration you feel through the steering wheel or the seat.
Balancing spins the assembly on a machine to find the heavy spot, then adds small counterweights to the rim to cancel it out.
Every new tyre should be balanced as it is fitted. We balance every wheel we fit, at your location — it is part of the job, not an extra.
Symptoms of imbalance
- Vibration that appears in a particular speed range, often around 50 to 70mph, and may fade above it.
- Through the steering wheel — usually a front wheel. Through the seat or floor — usually a rear.
- Came on suddenly, often after hitting something or after a tyre change where a weight was thrown.
Wheel alignment
Alignment is the angles at which the wheels meet the road: toe (pointing in or out), camber (leaning in or out at the top) and caster. The manufacturer sets these to fine tolerances.
They drift out through pothole strikes, kerbing, and suspension wear.
Symptoms of misalignment
- The car pulls to one side on a flat, straight road.
- The steering wheel is off-centre when you are travelling straight.
- Uneven tyre wear, especially on one edge or a feathered pattern — see reading wear patterns.
Do not diagnose pulling from road camber alone: most British roads slope towards the kerb, so a slight leftward drift on a normal road is not necessarily a fault.
Telling them apart quickly
| Balancing | Alignment | |
|---|---|---|
| Main symptom | Vibration | Pulling, off-centre steering |
| Speed dependent? | Yes — a band, often 50–70mph | No — present at all speeds |
| Tyre wear | Can cause cupping over time | One edge, or feathering |
| Usually appears | Suddenly, after a strike or a fitting | Gradually |
| Fixed by | Counterweights on the rim | Adjusting suspension angles |
| We can do it at your location | Yes | No — needs a workshop rig |
What we will do is tell you when the wear pattern points at alignment, so you can get it sorted before it eats a new set of tyres.
Things that are neither
Not every vibration or pull is a wheel problem, and it is worth ruling these out before paying for either job:
- Shaking only under braking — warped brake discs, not tyres.
- A droning hum that changes when you steer — usually a wheel bearing.
- Pulling that follows the road camber — most British roads slope towards the kerb.
- Uneven pressures — check these first; it is free and it causes pulling.
- A buckled rim — will not balance out, and shows up as soon as the wheel is spun.
Tyre noise and vibration works through the symptoms in more detail.
The order to do things in
If the car both vibrates and pulls, deal with alignment first, then fit and balance tyres. Fitting new rubber to a car that is out of alignment simply transfers the problem to the new tyres.
Alignment before new tyres, not after It is the single most common way people waste money on tyres — a fresh set fitted to a car that is still out of alignment can be visibly worn on one edge within a few thousand miles. How to tell if a tyre needs replacing covers what to look for.
Common questions
- How often should wheels be balanced?
- Whenever a tyre is fitted, and again if a vibration appears. There is no separate service interval — it is part of fitting.
- Is balancing included when you fit a tyre?
- With us, yes — it is part of the job, not an extra. It is worth confirming with anyone else, because a tyre fitted without balancing will vibrate.
- Can you align wheels at my house?
- No. Alignment needs a fixed rig and a properly level floor. Anyone offering roadside four-wheel alignment is not measuring it properly.
- Do balance weights fall off?
- Occasionally — stick-on weights can come away, especially after kerbing or in winter. A vibration that appears suddenly with no other cause is often exactly this.
- Does alignment affect fuel economy?
- Slightly, through increased rolling resistance. The bigger cost is tyre life.
