Tyre researcher Yi Xiong, who is involved in the LORRY project funded under the European Union’s Seventh Framework Programme (EU-FP7) and coordinated by Goodyear, says the idea behind it is to develop an innovative low rolling resistance truck tyre concept.

The project consortium comprised seven public and four private partners from European countries covering   fields such as tyre technology, rubber and filler technology, nanotechnology, transportation and vehicle engineering.

“The aim of the LORRY project is to reduce trucks’ carbon footprint by developing an innovative low rolling resistance tyre concept combined with a comprehensive tool box for fleet fuel saving management,” Yi told Polymers & Tyre Asia in an interview.

The proposed concept will go beyond current state-of-the-art and stakeholder or market expectations regarding tyre rolling resistance, mileage, driving safety, driving performance and material and manufacturing sustainability.

Steer and trailer tyres developed in the framework of the project will demonstrate a minimum 20 per cent gain in truck tyre rolling resistance. Truck tyre-wear and wet-safety performance levels will be improved additionally, he said.

For modern radial tyres, it has been established that the tyre rolling resistance can account for as much as 17-21 per cent of the total fuel consumption of ground vehicles, while the contributions are even higher for heavy duty vehicles.

“From a broader perspective, the greenhouse gas emissions from transport sector accounted for about 20 per cent of total global greenhouse gas emissions. Therefore, it is clearly demanded to lower tyre rolling resistance and therefore improve the vehicle energy efficiency and reduce CO2 emissions.”
