WOW System represents an alternate approach to balancing a rim and tire, totally changing the traditional corrective calculation on its head and saving the owner hundredths if not thousands of kilograms during the lifetime of the balancer.
- What is WOW (WIZARD of WEIGHT) system?
WOW is a new function that is designed to reduce the cost of ownership of a balancer by limiting the quantity of wheel weight required to balance a wheel to within an acceptable and satisfactory tolerance.
Traditionally when carrying out a "dynamic" balance the machine examines the dynamic imbalance (i.e. side to side) by looking straight at the rim in 2 planes (i.e. inner/outer).
WOW firstly eliminates completely the static imbalance (the bit that the driver really feels) and at the same time, based on several key parameters, calculates the minimum amount of corrective weight needed to bring the dynamic residual imbalance within acceptable limits.
- Apart from saving money on weights, does WOW offer other benefits?
Unquestionably the other major benefit has to be aesthetics. With wheel weights now being of larger size than traditional lead weights in order to achieve the same weight, anything that reduces the amount of visible weight has to be good. This, in turn, makes carrying out a behind spoke balance a much easier, tidier and more cost effective process.
- But is WOW still accurate?
In all honesty that is a point for discussion. Some wheel balancer manufacturers who have similar weight saving programs will hail them as being 100% accurate, but it depends on how you view "accuracy". It is certainly not "perfect", how can it be? But as already stated it does provide a balance within what we as a balancer manufacturer accepts as "tolerable". It is for this reason that economy programs are not, in our opinion, for every job. Particularly sensitive vehicles (or indeed customers!) may be best served using traditional, conventional balancing methods. But the beauty of WOW is that you have the flexibility to use it when you want: no need to turn the function on or off – just on-the-run you can decide to use WOW or not, while balancing a wheel.
- So does WOW means you no longer need using a TILT balancer to improve mounting and therefore balancing accuracy?
Absolutely not. Anything that improves the accurate mounting of a wheel will have a huge, positive effect on the balancing results. So, in fact, if you intend to operate an economy balance then using proper flanges like Centering Bushings or Stud Plates will improve its accuracy.
  Static Unbalance Dynamic Unbalance |
The WOW program permits a higher threshold, but remains under the "maximum tolerance" point deemed acceptable by the machine (and ultimately by the operator, as threshold can be set by the user). And remember, the static imbalance is still 100% eliminated, regardless of dynamic tolerance.
