|For best performance
the expected temperature range will vary from
track to track. Generally, optimum traction will
be generated when the pit lane temps show
180-200 degrees. Check with the tire technicians
at the event for the recommendations for that
particular track and car combination. Take
advantage of the temperature checking station
that will be set up during the practice session.
Use of Hoosier technicians measurements
eliminates variables in instruments and
procedure which can influence the data.
performance the tires will require around 3
degrees of camber. There will be a trade off in
maximum performance to maximize wear. Generally
1/2 degrees less than optimum will result in the
best compromise for wear and speed. Less than
2.5 degrees can result in excessive wear on the

better performance with spring/shock rates
higher than previous brands you may have run.
|These tires are molded
to their designed tread depth. They do not
require shaving to be prepared for competition
use. Shave the tire further will not improve
performance. It is not recommended that they be
altered in this manner.
|Due to extremely light
construction, the Hoosier tires have a much
lower polar moment than other radial tires. This
translates to a very low rotational mass, which
is a good thing for performance applications.
The down side to this feature is that the tires
don't resist "spikes" in braking force as well
as a heavier tire might. As a result,
there is a tendency for drivers to "flatspot" a
tire the first time really getting to the limit.
Vehicles equipped with ABS will benefit from its
use. If you do not use ABS it is recommended
that you make an effort to minimize stabbing the
brakes until you have some experience with the
feel of the tire under hard braking.

also provides less protection from impact damage
and punctures. Off course excursions or running
over debris on the track will likely result in

and maximize tire life.

lot of planning to make it work. The benefits to
doing it right include greatly increased tire
life as well as more consistent performance and
durability under stress. Please make an effort
to educate your team on the importance of this.
It can save you a lot of money.
|The Hoosier D.O.T.
Radial tires are extremely good in dry
conditions, however they don't make very good
wet weather tires. Having dedicated rain tires
available will be necessary for your team to be
properly prepared. Hoosier makes a D.O.T.
approved bias-ply tire called a "Dirt Stocker"
that has been proven to be far superior to any
competitors tire as long as it is a steady "wet"
condition. Check with your Hoosier
representative for size availability.
