In 2019–20 Sainsbury’s reviewed the tyre policy on its fuel tanker fleet. It wanted the lowest total cost of ownership, balancing tyre cost with real-world fuel performance, rather than the cheapest pence-per-kilometre rate. Goodyear commissioned Dynamon to forecast fuel consumption for each proposed policy in that operation. The forecasts were produced in Tyre Analytics.

Key outcomes
- 2019–20 was when Sainsbury’s reviewed the tyre policy on its fuel tanker fleet of articulated tractor units and tanker trailers.
- Operation-specific forecasts set out the fuel consumption of each of Goodyear’s proposed policies in the Sainsbury’s tanker operation.
- Independent evidence of the fuel and total-cost performance, which Goodyear could present to Sainsbury’s for each proposed policy.
The challenge
In 2019–20 Sainsbury’s was reviewing the tyre policy on its fuel tanker fleet. The vehicles were articulated tractor units with tanker trailers. Sainsbury’s wanted the policy that balanced tyre cost against real-world fuel performance, so as to give the lowest total cost of ownership, rather than the cheapest pence-per-kilometre rate.
Goodyear commissioned Dynamon to forecast the fuel consumption of each policy it proposed, for the Sainsbury’s tanker operation specifically, so that fuel cost could be weighed against tyre cost. The proposed policies drew on Goodyear’s FUELMAX and KMAX ranges.
The fleet
Sainsbury’s is the UK’s second largest grocer, serving customers in stores and online. J Sainsbury plc is based in London, and the business operates petrol stations. Goodyear, headquartered in Akron, Ohio, in the United States, develops and manufactures tyres, including commercial tyres for trucks.
This analysis covers the articulated tractor units in Sainsbury’s fuel tanker fleet, and the tanker trailers those units pull.
The approach
Dynamon built a baseline from the tyres fitted at the time and from the fleet’s telematics and vehicle data, then forecast each proposed policy.
Tyre Analytics models the energy each vehicle uses second by second — aerodynamic drag, tyre rolling resistance, acceleration, hill climbing, and engine and auxiliary losses — from telematics, vehicle configuration and tyre fitment data. That lets it predict how a change of tyre policy would affect fuel consumption and total cost in the fleet’s own operation.
What the analysis showed
The forecasts set out fuel consumption for each of Goodyear’s proposed policies in the Sainsbury’s tanker operation. They were based on that fleet’s telematics, its vehicle data and the tyres fitted at the time, so they described this operation.
Goodyear could present Sainsbury’s with independent, operation-specific evidence of the fuel and total-cost performance of the policies it had proposed. That evidence let fuel consumption be weighed against tyre cost, for the total cost of ownership the review was seeking.
