Solving the Mystery of the Power Spoke Wheel Balancing Tool
In preparation for winter today, I removed the Power Spoke wheels from my MINI Cooper SE, replacing them with some slightly used Loop Spoke wheels. For weight-of-wheels aficionados, my cheap bathroom scale said a 17" Power Spoke with a Hankook Ventus S1 EVO3 tire weighs 38 pounds and a 16" Loop Spoke with a Hankook Ventus S1 EVO2 HRS tire weighs 36 pounds.
In our last episode of "Balancing the Power Spoke Wheel" we saw the strange piece of plastic that MINI created to accomplish this task. It says something that the designers persuaded MINI their asymmetrical wheel was so wonderful that it was worth all the trouble of making a special tool to balance it. And worth all the trouble owners might experience if their tire store didn't have this device. Of course, MINI assumes all MINI owners go to their dealer for all their service needs.
Here is a Power Spoke wheel with the asymmetrical wheel cover removed using the special wire hook that comes in the Puncture Repair Kit of Iconic-trim SE's that were ordered with the Power Spoke wheels. The wheel cover clips into the center hole and the round hole on the right.
When I looked at the reverse side of the wheel cover, I discovered a sticker. It was obscured by brake-pad dust, but I wiped it off and it revealed that the balancing tool is nothing more than a weight that clips into the right hole. Evidently, it simulates the off-center weight of the asymmetrical wheel cover, making it possible to balance the wheel without the wheel cover being in place. Note that the sticker's third step is to remove the tool after balancing is complete.
I wonder why the tool/weight is shaped the way it is? How many of these tools did MINI make to satisfy world-wide demand? How much does this piece of plastic cost? I'll have to call my MINI dealer. Is my Iconic MINI Cooper SE complete without having one? Does it come in both green and orange? Do I need one of each color? It's so hard being the custodian of Power Spoke wheels!
