Pinewood Derby Wheels

When a race can be won by a fraction of a second, it is important that your car has every advantage.

• Outer tread is precision lathed to perfectly tune and true this wheel, removing all imperfections while being careful to keep the beads along the wheel rim.
• Inner tread is precision lathed, once again removing all imperfections.
• Hub is precision lathed to perfectly tune and true the hub to the center bore.
• The hub is squared so there is a perfectly flat surface meeting the car body, eliminating wobble when the wheel hub touches the car body
• The wheel rim is squared so there is a perfectly flat surface when the wheel rubs the track center guide. This reduces friction and reduces the chance of wobble.
• Wheel is lighter, giving you a fast start out of the gate because a lighter wheel requires less energy to get started than a heavier wheel.
• All four wheels come from the same mold so they are perfectly matched.
• We make all these improvements and carefully leave all BSA lettering, tread beads and markings intact.

Why lathe the treads?
Because it is like a car with unbalanced wheels!
Wheel imperfections will cause uneven rotations, however small, with each revolution, reducing speed.
With precision tread lathing, your wheel is perfectly round and trued to the center bore giving you maximum speed.

What is a "trued" wheel?

Precision lathing "trues" the wheel tread to the axle center line,
meaning the tread is now perfectly concentric with the axle,
giving you perfect precision rotation.

Why square the hubs?
Once again, imperfections in the plastic cause friction where the wheel rubs against
the pinewood derby car body, slowing your car down.
The hub is squared because friction is reduced and wobble is reduced if two perfect 90 degree surfaces meet each other. The BSA wheel hub is rounded (coned) too much! We flatten this surface to reduce friction and wobble, therebyincreasing your derby car speed.

Why do you want lighter wheels?
Lighter wheels are easier to turn, giving you a
faster start and increased speed
as your derby car races down the track.

Why ream the wheel bore?
Like the other areas of the wheel, the bore has imperfections and
may not be trued to the rest of the wheel. When the bore is reamed,
your pinewood derby car wheel rotates perfectly about the axle.

Why trim the rim?
The rim has imperfections that slow your pinewood derby car whenever the wheel rubs
against the center rail.
Trim the rim, reduce friction and increase your speed!

All wheels are not created equal. There are many slight differences between each mold when they are made. To achieve optimal performance, your wheels are matched as a set, giving you perfect balance.
