The collaboration between Bridgestone and Coventry University also found that 33 percent of CO2 emissions could be reduced if all regional UK HGVs used Duravis (EU label grade: B class) tyres.
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.
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. There would also be savings of 1,100 litres and 1,600 litres on Ecopia tyres, which translates into £2,200 and £3,200 of annual financial savings.
An HGV would be able to reduce its CO2 emissions per annum between 22 percent to 28 percent on Duravis tyres and between 25 percent to 33 percent on Ecopia tyres.
These 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.
