HOT AIR PRESSURE
This represents the amount of air pressure present 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.
TIRE TEMPERATURES
This represents the 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 is 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.
TREAD REMAINING
The amount of tread remaining on the tire once the car has returned from 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.
AERODYNAMICS
WING SETTING
The wing setting refers to the relative angle of attack of the rear wing; this is a powerful aerodynamic device which has a
significant impact upon the total downforce (and drag!) produced by the car, as well as shifting the aerodynamic balance of the car
rearwards with increasing angle. Increasing the rear wing angle results in more total cornering grip capability in medium to high
speed corners but will also result in a reduction of straight line speed. Rear wing angle should be adjusted in conjunction with front
and rear ride heights, specifically the difference between front and rear ride heights known as “rake”. To retain the same overall
aerodynamic balance it is necessary to increase the rake of the car when increasing the rear wing angle.
AERO CALCUL ATOR
This calculator is a reference tool ONLY.
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.
