HO T AI R PRES SURE
Air pressure in the tire after the car has returned to the pits. The difference between cold and hot pressures can be used to
identify how the car is progressing through a run in terms of balance, with heavier-loaded tires seeing a larger difference between
cold and hot pressures. Ideally, tires that are worked in a similar way should build pressure at the same rate to prevent a change
in handling balance over the life of the tire, so cold pressures should be adjusted to ensure that similar tires are at similar
pressures once up to operating temperature. Hot pressures should be analysed once the tires have stabilised after a period of
laps. As the number of laps per run will vary depending upon track length a good starting point is approximately 50% of a full fuel
run.
T IRE T EMPER AT URES
Tire carcass temperatures, measured via Pyrometer, once the car has returned to the pits. Wheel Loads and the amount of work
a tire is doing on-track are reflected in the tire's temperature, and these values can be used to analyze the car's handling balance.
Center temperatures are useful for directly comparing the work done by each tire, while the Inner and Outer temperatures are
useful for analyzing the wheel alignment (predominantly camber) while on track. These values are measured in three zones across
the tread of the tire. Inside, Middle and Outer.
T RE AD REM AINING
The amount of tread remaining on the tire once the car has returned to the pits. Tire wear is very helpful in identifying any possible
issues with alignment, such as one side of the tire wearing excessively, and can be used in conjunction with tire temperatures to
analyze the car's handling balance. These values are measured in the same zones as those of temperature.

AERO CALCULATOR

The Aero Calculator is a tool provided to aid in understanding the shift in aerodynamic
balance associated with adjustment of the rear wing setting and front and rear ride
heights. It is important to note that the values for front and rear ride height displayed here
DO NOT result in any mechanical changes to the car itself, however, changes to the rear
wing angle here WILL be applied to the car. This calculator is a reference tool ONLY.
FRON T RH AT SPEED
The Ride Height (RH) at Speed is used to give the Aero Calculator heights to reference for aerodynamic calculations. When using
the aero calculator, determine the car's Front Ride height via telemetry at any point on track and input that value into the "Front
RH at Speed" setting. It is advisable to use an average value of the LF and RF ride heights as this will provide a more accurate
representation of the current aero platform rather than using a single corner height.
