RFID - Radio Frequency Identification Device – providing live tyre information for LM24

Motorsport has seen technology used to make the sport more accessible to viewers and spectators – this year will see the Le Mans 24 Hours enhanced by the availability of tyre information during the race.

During the race, the organisers (the ACO) will be able to access and broadcast the tyre choice and number of stints completed on each set of tyres for the teams competing in the endurance epic. With tyre strategies forming a fundamental part of the race, the information will increase viewer knowledge and increase the excitement as 60 teams battle for the wins and podiums.

Dunlop has been instrumental in the development and introduction of RFID over the last decade, being the first tyre manufacturer to introduce the technology in motorsport. The technology has been in place since 2008 when Dunlop worked with TOCA, the organiser for the British Touring Car Championship, to create and implement a system to make monitoring tyre use to meet regulations much easier. Six years later the system was introduced into sportscars, with 2015 being the first full season when the technology was used to aid tyre control.

This is the third generation of Dunlop’s RFID software being used; this current version enables reading the RFID chips from greater distances, guaranteed accuracy and more detailed information for data use and analysis.

In addition to providing information to viewers, RFID provides a cost effective way of managing availability and use given the thousands of tyres involved. It also provides a security feature – the chip embedded in the tyre can’t be removed like a barcode.
