SET-UP TYRE
In the motorsport the tires features are today the starting
point to begin the work, both in the vehicle development, both
in the setup phase. Also in the kart this aspect has a
fundmental importance, but unfortunately there aren’t the
necessary informations and technical knowledges, therefore it
comes neglected, and the technical choices are made for
attempts, using only the experience of a good mechanic, and the
sensations of a good driver. Thanks to the software SET-UP TYRE
you can instead know the tires features and to find the optimal
inflation pressures to have the best setup more easily, and
above all to satisfy more fastly the needs of each driver for
his driving style. |

|
How it works?
|
With this new software we’ve developed a series of calculations that
allow to determine the tyres features simply making easy geometrical
measures.
You’ll need of a meter, a pressure gauge, and of a few of string,
and simply measuring, the circumference and the section perimeter
of the tire, and the dimensions of the rim, at a couple of inflation
pressures, and the software we’ll be able to calculate the effective
structural features of the tire.
| TYRE MEASUREMENTS |
 |
If you don't have the possibility to perform the measurements, for a
starting calculation you can use the data provided from the
manufacter on the homologation fiche.
|
This is important to
understand fastly the behavior of each brand and model of
tire, but also to verify if there are difference between a
set and another of the same tire model, in fact one of the
problems that often there are in the kart is the stability
of the tire features, not for the compound, but for the
structural behavior.
Entering then the kart features and the acquired
informations that allow to characterize the track, the
software can calculate the loads acting on the wheels in the
different driving phases, and to find the optimal inflation
pressure for each condition.
|
| KART and ACQUISITION
DATA |
 |
In fact the tyres features are hightly affected from the inflation
pressure (read our paper if you want deepen), therefore the choices
of pressure for the front wheels, the rear wheels, and the chassis
setting, should be all coordinated to obtain the maximun in each
phase of the driving.
Thanks to this software then you could understand how change, the
grip level, the basic trim (understeer / oversteer), and the entity
of the power loss for the rolling resistance, in function of the
inflation pressure.
To find then the optimal inflation pressures for your needs will
result easy, and you'll allow to improve fastly the performance and
the driveability in each condition.
|
Results |
In function of
geometric and structural features,
the software calculates how change the tyre
performances changing the inflation pressure.
The software shows the graphs of the performances
comparing the results of the front tyre and of the
rear tyre. |
| TYRE
PERFORMANCE |
 |
This allows to
understand immediately the pros and cons of the
choices for the inflation pressures that you want
make.
Entering in the software the inflation pressures
that you want use, you'll be able to understand,
again more in the detail, the tyre and the kart
performance that you'll obtain. |
| TYRE
PERFORMANCE at the USE PRESSURE |
 |
The software in fact calculates for
these pressures:
- front and rear slip angle in the middle of the
corner
- trim conditions (oversteer / understeer) in the
middle of the corner
- front and rear grip level
- power on average lost to win the rolling
resistance
|
|
| COMPARISON
PERFORMANCE with DIFFERENT PRESSURES |
| Comparing different
choices for the inflation pressures you'll be able
to find easily the best solution for your needs. |
 |
For example in the
image beside, using the pressures of the test 2 you
reduce the understeer, and you increase the grip
both at the front, both at the rear, but you
increase, both the power lost for rolling, both the
slip angle. In function of the track features, and
of the driver needs, you'll be able therefore to
understand easily which solution choose. |
|
| MAIN USES |
| - |
To modify the kart trim, increasing or
decreasing the understeer, or the oversteer,
simply acting on the inflation pressures. |
| - |
To work on the inflation pressures to
improve the corner speed increasing the grip |
| - |
To work on the inflation pressures to
improve the straight speed, decreasing the
power losses |
| - |
To foresee how the kart trim will
change from the begin to the end of the
race for the different warm-up of the front
and rear tires, that will go to modify the
pressures. |
|
| OPTIMAL
INFLATION PRESSURE CALCULATION |
| In addition the
software calculates the inflation pressures that
allow to have the best comprimise between grip,
rolling resistance, and slip angle. |
 |
| Since that the loads
change in the different driving conditions, the
advised pressures will be differents, will be then
the technician to make the final choice in function
of the track, or the driving style of the driver,
favoring one phase over the others from time to
time. |
With this instrument you’ll have then the possibility to
combine the choices of setup to those of the tire pressure,
so you can improve consistently the driving and the lap
performance in each situation.
