Pinewood Derby Wheels by Derby Dust

To the new to novice builder there can be great confusion in wheel choice.  What does all this technical info mean?  What does my Pack allows?  There is no blanket BSA rule that cover all wheels.  Each local PACK determines what wheels can and cannot be used.

Below is a run through of each wheel we offer with the as much info as we can provide.  We will place them in order from slowest to fastest.  Mostly this will be based on wheel weight.  The lighter the wheel, the faster the car. Proven concept, not mathematical.

All measurements are averages and may not be actual per your specific wheel.
OD-Outer Diameter
AWW- Average Wheel Weight.
MM-Mold Match  — Some believe that if wheels come form same mold, they will be the same wheel.  We know that each wheel is different regardless what mold it comes from.  Be careful as the mathematical likelihood that you will get all 4 wheels out of box to match is stupid high.
MIB- Matched Inner Bore +/- 0.0005″  We measure out wheels to determine which wheels have the same inner diameter.  A much more scientific version of the “mold match” theory.
