7.2.2.2 Dynamic measurements
Tyre dynamic characterization describes changes in dimensions due to speed and vertical load. All measure-
ments are made without any applied camber (0°) with the tyre inflated to 1.4bar/ 20.3 Psi
Loaded radius LR [mm]
distance between the wheel center and the ground;
Rolling radius RR [mm] the length travelled by the tyre for each wheel's revolution divided by 2p.
7.2.2.3 Operating instructions
Before each run
Pressures:
•
The tyre pressure must always be over the declared minimum running pressure defined within this
book.
After each run
Temperatures
•
the offset in measured garage bulk temperature between the inside and outside of the tyre should
not exceed 20°C for optimum tyre performance
•
the offset in measured garage bulk temperatures between front and rear axle should not exceed
25°C for optimum tyre performance
Pressures
•
the measured garage pressure should be as close as possible to the hot target value stated within
this book
•
Dry air is recommended to inflate tyres to avoid sudden changes in pressure due to humidity.
•
all pressure limitations (cold and hot) stated in this book will be monitored during each event, and
modified if deemed necessary.
