Michelin appointed Dynamon to run its Global Tyre Trials, a programme of controlled real-world trials in European fleets. The trials compare the fuel performance of Michelin X Multi Energy with Michelin X Multi. On Groupe Alainé’s tractor units in France, Precision Trial Analytics followed both phases from August 2023 to June 2024, using the fleet’s telematics.

Key outcomes
- Two phases ran from August 2023 to June 2024 on Groupe Alainé’s tractor units in France.
- Several data sources were read together: AddSecure telematics, load information supplied by the fleet, and the fuel card records.
- An overall fuel saving was measured in favour of Michelin X Multi Energy against Michelin X Multi across the full trial.
The challenge
Michelin needed the fuel performance of Michelin X Multi Energy measured against Michelin X Multi in working fleets. In daily service, fuel use shifts with speed, acceleration, hill climbing, load and the way each vehicle is driven, so the vehicles on trial have to stay comparable.
The Global Tyre Trials are Michelin’s programme of controlled real-world trials in European fleets, which Dynamon was appointed to run. For Groupe Alainé, the trial covered tractor units in France, in two phases, from August 2023 to June 2024.
The fleet
Groupe Alainé is a family-owned, independent transport and logistics group based in Mâcon, France. It moves goods by road across France and Europe, and also offers forwarding, overseas and cleaning services. Michelin, which manufactures the tyres under trial, is headquartered in Clermont-Ferrand, France.
The vehicles in the trial are the group’s tractor units operating in France. Their AddSecure telematics provided the operating and fuel data that Dynamon analysed.
The approach
Precision Trial Analytics follows four steps: predict the expected saving to set the trial size and duration; design matched test and control groups; monitor operating behaviour — speed, acceleration, hill climbing and load — throughout, so the groups stay comparable; and analyse fuel consumption, so any difference can be attributed to the tyres rather than to how the vehicles were driven.
Dynamon connected to this fleet’s AddSecure telematics through its API and combined it with load information the fleet supplied.
What the trial showed
Over the full trial, Dynamon measured an overall fuel saving in favour of Michelin X Multi Energy compared with Michelin X Multi. The comparison covered both phases, from August 2023 to June 2024, on the tractor units in France.
Dynamon checked telematics fuel data against the fleet’s fuel card records to ensure the fuel figures were accurate. With the load information supplied by the fleet, cross-checking several data sources gave confidence in the result.
