ISO 18164:2005

ISO 18164:2005 specifies methods for measuring rolling resistance, under controlled laboratory conditions, for new pneumatic tyres designed primarily for use on passenger cars, trucks, buses and motorcycles. The relationship between values obtained and the fuel economy of the vehicle is undetermined, and such values are not intended to be used to indicate levels of performance or quality.
ISO 18164:2005 applies to all passenger car, truck, bus and motorcycle tyres.
