What would the environmental – and financial – impact be if all heavy goods vehicles in the UK switched to high performance tyres, engineered with low rolling resistance to reduce fuel consumption and carbon emissions?

Bridgestone teamed up with Coventry University to calculate the saving that could be realised if regional and long-haul fleets switched from standard class D tyres to Bridgestone Duravis (EU label grade: B class) and Ecopia (EU label grade: A class) tyres respectively.

Duravis and Ecopia tyres have been engineered to achieve lower RRC (Rolling Resistance Coefficients) than class D tyres, which means reduced energy loss, fuel consumption, and CO2 output.

Annual CO2 emissions savings 

• If all UK Long-haul HGVs used Ecopia Tyres, 31% of CO2 emissions could be reduced.
• If all Regional UK HGVs used Duravis tyres, 33% of CO2 emissions could be reduced.

With the ongoing cost-of-living crisis, Commercial Fleet Partners would face increasing economic demands. Finding ways to reduce their Total Cost of Ownership (TCO) would help to mitigate this. 

How much fuel could you save?

Based on a fuel cost of £2 per litre, an HGV per year would be able to save:

• Between 650 litres and 950 litres on Duravis tyres, which translates into £1,300 and £1900 of annual financial savings.
• Between 1,100 litres and 1,600 litres on Ecopia tyres, which translates into £2,200 and £3,200 of annual financial savings.

How much CO2 could you save?

An HGV fitted with Duravis or Ecopia tyres would be able to reduce its CO2 emissiones per annnum by:

• Between 22% to 28% on Duravis tyres.
• Between 25% to 33% on Ecopia tyres.

This results were calculated on the premise that all vehicles would be running on ‘D class’ tyres and would be swapping to the ‘A class’ Ecopia range on all axles, referencing a number of sources including official Department for Transport statistics.
