Bridgestone Europe asked Dynamon to measure the fuel performance of Bridgestone Duravis tyres in real-world operation. The trial ran in the German distribution fleet of REWE Spedition und Logistik, the logistics arm of the REWE Group. Dynamon designed, monitored and analysed it with Precision Trial Analytics, so the comparison rested on the tyres rather than on how the vehicles were driven.

Key outcomes
- 18 tractor units in real-world use in REWE’s German distribution operation, split into three equally sized groups.
- Six vehicles each with one group on Bridgestone Duravis tyres and two groups on alternative premium tyre policies.
- A measurable fuel saving from the Duravis group against both comparison groups, over around six months of operation in 2022–23.
The challenge
Bridgestone Europe manages Bridgestone’s tyre operations for Europe, the Middle East and Africa from Belgium. It commissioned Dynamon to design, monitor and analyse a real-world trial of Bridgestone Duravis tyres in the German distribution operation of REWE Spedition und Logistik.
In operation, fuel consumption moves with speed, acceleration, hill climbing and load. Without groups that stay comparable on those factors, a fuel difference can come from how the vehicles were driven rather than from the tyres. Before connecting to the fleet’s telematics, Dynamon set up a data processing agreement and met REWE’s information-security requirements.
The fleet
REWE Group is a trade and tourism company headquartered in Germany, and food retail is its largest core business segment. A warehouse and transport system supplies its stores.
REWE Spedition und Logistik GmbH, the group’s logistics arm, operated the 18 tractor units in this trial. They were split into three groups of six in the German distribution operation, one on Bridgestone Duravis tyres and two on alternative premium tyre policies.
The approach
Dynamon used Precision Trial Analytics to design, monitor and analyse the trial.
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.
What the trial showed
The trial ran for around six months in 2022–23 in REWE’s German distribution operation. Dynamon monitored all three groups throughout and then analysed the fuel each had used.
The Duravis group delivered a measurable fuel saving against both comparison groups. That gave Bridgestone independent, fleet-specific evidence of how Duravis tyres perform in real-world operation, measured on a working distribution fleet. Because the measurement came from live service, it reflects the fleet’s own duty cycle.
