As a result of Pirelli’s collaboration with the FIA to ensure a better monitoring of tyre usage parameters, the Italian firm is trialling a special type of sticker on each tyre tread in Bahrain.
These stickers read the maximum temperature reached by the tyre tread while the tyres are being pre-heated by the teams in their tyre blankets.
Pirelli prescribes a maximum temperature of 110°C (230°F), which should not be exceeded at any point before the tyre takes to the track.
The FIA will ensure that this limit is respected, together with the minimum tyre pressures when leaving the pits and maximum camber levels on the track.
