Balancing tires
From JeepForum.com Community Jeep Wiki
Tire balance, also referred to as tire unbalance or imbalance, describes the distribution of mass within an automobile tire and/or the wheel to which it is attached. When the tire rotates, asymmetries of mass cause the wheel to wobble (Taken from here)
This wobbling can give rise to ride disturbances, usually vertical and lateral vibrations. The ride disturbance due to unbalance usually increases with speed. Vehicle suspensions can be excited by tire unbalance forces when the speed of the wheel reaches a point that its rotating frequency equals the suspension’s resonant frequency.(Taken from here)
Tire balancing solutions
You can balance tires statically using a balancing machine and then applying wheel weights or you can try a dynamic solution. The later is where the balancing weights are inside the tire and move freely.
Dynamic balancing becomes more favorable of a solution for two common reasons. First, if the added weights are toward the center of the tire then they will have less centripetal force thus require you to have more weights. Second, if you like to lower your tire pressure and go off road then you may find your weights will pop/fall off.
Dynamic balancing implementations
- Airsoft/plastic BBs (The cheap effective solution but requires you to break the bead of your tire)
- dynabeads (the more expensive solution but has a special "applicator" to insert the weights through the valve stem)
- others exist where the weight inserted into the tire is a liquid. Here is an example of a commercial product
