Wheel Balancing: What, Why and How?

Tyres work well when their weight or mass is equally distributed and consistent throughout. The wheel or tyre loses its balance temporarily due to unavoidable pebbles, tar, debris, ice, or snow present on the roads. This foreign material gets plunged into your tyre’s tread which results in unbalanced wheels. Under the wheel balancing process, the technicians evenly and properly distribute the weight throughout each of the wheels and tyres on a vehicle using weights (lead alloys). They even the light and heavy wheel spots out for smooth movement. Correctly balanced wheels are crucial to your vehicle’s performance, safety, and life. Unbalanced wheels disturb your rides at higher speeds by impacting vehicle suspensions; moreover, they make your tyres wear quickly and unevenly. There are many ways you can sense the need for wheel balancing.

Go For Tyre Balancing When You:

  • Buy new tyres for your vehicle

  • Perceive vertical and lateral vibrations or oscillations in the steering wheel

  • Have driven your vehicle over 5,000 miles

  • Get your flat tyre fixed

Now you have some idea about what wheel balancing is… why the need of the same arises and how do you suspect it. Let’s focus on how it is done.

The very first step in the process is to measure the amount and angle of imbalance with the help of spin-balancers (static balancers and dynamic balancers). The balance weights are next inserted into the outer and inner ribs of the wheel in order to achieve even weight distribution. Below given is a brief about both the methods.

Static Balance: is lost when the wheel’s centre of mass is shifted from its vertical axis of rotation due to gravity forces, which is corrected by putting it back at the centre of the axle (on which it is mounted). It is measured by placing the tyre on a vertical, non-rotating spindle on a static balancing machine.

Dynamic Balance: needs realigning the principal axis of the tyre’s moment of inertia with the axis (about which the tire rotates), usually the axle on which it is mounted. Under this procedure, the tyre and wheel are mounted on the test wheel of a balancing machine. Then the technician rotates the assembly at the speed of 100 RPM or higher (10-15 mph with recent high sensitivity sensors) and 300 RPM (55 to 60 mph with typical low sensitivity sensors). Then he measures the forces of imbalance using sensors that are resolved into static and couple values for your wheel’s inner as well as outer planes. These values are compared with the highest allowable manufacturing limits (unbalance tolerance).

Most drivers are unable to identify the symptoms of wheel imbalances. However, abnormal vibrations are any which way not good for your vehicle and should be treated without any delay. As soon as you suspect unusually vibrating steering wheel, you should take your vehicle right away to an authorized auto repair shop such as Nil’s Tyre Services. Under the roof of their full-fledged workshop, your vehicle will be treated by expert technicians using the latest equipment. They provide all sort of tyre services at very nominal service charges.
