SÃO PAULO, Brazil — With the purpose of providing tire performance information to consumers during their purchase experience, Brazil's Inmetro (National Institute of Metrology, Quality and Technology) and Bridgestone Corp. have established criteria that they said should be mandatory in all tires produced and imported in Brazil starting from Oct. 29, 2016.
According to Inmetro Ordinance No. 544/12, the Brazilian Labeling Program (PBE) information that will be on the national energy conservation label (ENCE) will be rolling resistance, wet track grip and external noise. The label will be located on the tread of radial tires for cars, pick-up trucks, SUVs and vans, as well as radial tires for trucks and buses.
“These criteria were chosen because they are related to environmental impacts (bearing resistance, which interferes with fuel consumption and noise emission) and vehicular safety (grip on a wet track),” said Concheta Feliciano, marketing director for Bridgestone Brazil.
The new label will feature factors that affect tire performance, including:
Rolling resistance — It is directly related to energy efficiency, since it measures the energy absorbed when the tire is rolling, according to Bridgestone. “Thus, the lower the rolling resistance, the lower the fuel consumption and, consequently, the lower the impact on the environment (CO2emission).”
On the label, the tires will be classified in up to six levels, with “A” being the most efficient and “F” being the least efficient.
Grip on wet track — This performance indicator provides consumer information about tire grip on wet tracks. Performance scales will range from “A” (best performance) to “E” for heavy touring vehicles.
