The vibration is the symptom, not the problem
No tire and wheel assembly is perfectly even. At low speed that is harmless. As the wheel spins faster the heavy spot is thrown outward harder, until it shakes the whole vehicle.
Balancing measures where the assembly is heavy and adds counterweights to even it out. What it prevents is not just discomfort:
- Patchy tread wear, which shortens the life of a set you have just paid for.
- Suspension and steering wear, from components being shaken continuously.
- Casing damage on commercial tires, which can cost a casing its retread life.
When to have it done
Whenever a tire is fitted, which is standard practice here. When a vibration appears at a particular speed and fades above and below it. After hitting something hard enough to knock a weight off, or if a wheel weight is visibly missing, which is worth looking for after a curb strike.
Balancing is not alignment
They get confused constantly, and the quick version is worth having:
- Balancing fixes a vibration. It is about weight distribution around the wheel.
- Alignment fixes a pull, a crooked steering wheel and uneven wear across the tread. It is about the angles the wheels sit at.
Both can be true at once, which is why a store looks at both when a new set goes on.
Commercial assemblies too
This is not only a car service. Commercial truck assemblies are balanced for the same reasons and with more at stake, because the vibration is being fed into a vehicle covering far more miles. Fleets running a Purcell account have balancing built into fitting as standard.
