Role of innerliners in improving "in-use rolling resistance"
The case study results show an IPLR < 1.8% would provide a benefit of reduced fuel consumption by 4.5 gal/year. In the future, it is not a stretch to expect that an IPLR < 1.8% will be the target IPLR specification for global OEM leaders in the next 5 years. It is beneficial for OEMs and tire makers to revise IPLR specifications to the next generation level of < 1.8%.
