What is balanced wheel?

Answer 1

Placing weights on the rim of the wheel so the tire rotate in a uniform manner. If it is not balanced properly, the tire wheel will wobble, and create a vibration that the driver and passengers will feel.

There are two types of wheel balance: Static and Dynamic. Dynamic balancing is usually the preferred method. A tire and wheel may be in static balance and still have dynamic unbalance. Either static or dynamic unbalance will cause the steering wheel to shake from side at higher speeds.

When you put your cell phone on vibration mode. when some one calls you it starts vibrating. This cellphone vibration occurs because of unbalance mass is rotating at high speed by motor inside the phone.

Same thing happen with cars. some unbalance mass on rotating parts like wheel and tire assembly, fly wheel, etc. They case vibration when they rotate at high speed and this is not preferable. So we need to do the balancing of rotating pats of the car mainly wheels.

Answer 2

The wheel and tire are locked onto a spinning drum that detects imbalance which is then corrected by clamping small weights to the rim of the wheel. This is vital to prevent tires wobbling at high speed.
