About Tires & Inserts
REAR TIRES
Tire choice is one of the most crucial
choices a racer has to make.
How do I know which tire to use?
The harder the surface, the smaller the
pin or spike on the tire. If the surface is
soft or has a loose layer on top, the tire
pin or spike will become longer to try
and get down to the harder surface
below.
The smoother the surface, the softer the
tire compound can be. With rougher
surfaces, choose medium compound.
Grass calls for hard compounds.
Rougher surfaces and many corners
favor rounded profile tires for their
cornering traction. Smoother surfaces
favor flatter profile tires for their
maximum flat surface traction.
Choose the tire that the most successful
racers are using at that track. This saves
you money--it keeps you from buying
tires that won't work on the track.
FOAM TIRE INSERTS
Today's tires are thin and need support
to retain their shape. Tire inserts give
this support.
How do I know which foam to use?
The foam insert's density is important.
The foam insert that comes with the tires
nine times out of ten is the insert you
should use.
Too firm an insert will cause your car to
bounce, resulting in loss of traction.
Too light a foam will cause the car to
wander and to be very unstable.
TIPS FOR TIRES
1. With one piece rims,
glue the tires to the
rims with CA.
Remember afterwards
to vent the tires with a
small hole so they
won't bounce.
2. Try applying tire
traction compound to
all four tires when
encountering slick
surfaces. Use traction
compound when on
dry, clean tracks when
you need more
traction, especially
through the corners.
TIP FOR INSERTS
1. Trim your foam
inserts at the inside
edge of the foam. This
will allow the beads of
the tire to fit to the rim
better and the foam will
also support the tire
much better.
