You know why I don’t trust Inmetro, the National Institute of Metrology, Quality and Technology, the government agency responsible for approving and certifying products that are placed on the market. When it comes to tires, Inmetro is always slipping and sliding.
So much so that he has already allowed retreaded tires, contrary to the rules established in the first world to increase the safety of those using these types of components that should not be bought.
But Inmetro slipped again when it comes to tires. He introduced a label with three characteristics noise level, wet grip and rolling resistance but he didn’t introduce a requirement to put the tire on what buyers care about most.
Some tires, particularly those sold in the United States, have the Treadwear engraving, which provides information about their durability.
The tip that Inmetro won’t give you is know the durability of the tires
When you buy a tire like me, you want to know which tire will last the longest. Is it or isn’t it? But if you buy a tire that isn’t exported to the US, it doesn’t have socalled treadwear on the sideband. Because in the USA, for example, you have to specify the durability of the tire.
If you look for the label on the tire required by Inmetro, you will not find durability, but other properties. Setting durability is said to make life much more difficult for tire manufacturers. And Inmetro always acts not to complicate their lives, but it complicates us, the consumer’s.
So when you buy the tire you should know that some brands that export offer treadwear ranging from 60 to 600. The higher this number, the longer the tire will last. However, this is not available for all tires, only for exported ones. There? Because of Inmetro!
