Bridgestone Explains the Brazilian Tires Labeling Program
With the purpose of providing tire performance information to consumers during purchase, the Inmetro (National Institute of Metrology, Quality and Technology), through the Brazilian Labeling Program (PBE), established criteria that should be mandatory in all tires produced and imported in Brazil from October 29, 2016.
According to Inmetro Ordinance No. 544/12, the 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-ups, SUVs, vans and pickup truck, 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)”, says Concheta Feliciano, Marketing Director at Bridgestone Brazil.
How to read the new label?
It is directly related to energy efficiency, since it measures the energy absorbed when the tire is rolling. Thus, the lower the rolling resistance, the lower the fuel consumption and, consequently, the lower the impact on the environment (CO2 emission).
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
It is a performance indicator that provides consumer information about tire grip on wet tracks. Performance scales will range from "A" (best performance) to "E" for heavy touring vehicles.
This classification affects the distance traveled by the vehicle on a wet track after braking.
This criterion indicates the level of noise produced by the tires in decibels (dB) and, consequently, the impact on the environment (less noise pollution). This criterion should have as maximum limit up to: 75 dB for touring vehicles tires, 77 dB for light commercial vehicle tires and 78 dB for truck and bus tires.
Inmetro Ordinance No. 544 is not applicable to retreaded tires, bicycle tires, tires for use in agricultural vehicles only, tires for racing vehicles, military vehicles, industrial vehicles and forklifts. In addition, tires for motorcycles, scooters, mopeds, collection vehicles, diagonal tires, off-road tires, tires for temporary use only, and commercial vehicle tires and radial type towed tires designed for several uses only on the drive axle are supported by Ordinance 544. These models have been excluded from performance testing and therefore will not have labels.
