You throw away some shoes that just need to be cleaned, or the tube of toothpaste before you get to the end? So why change tires when they still have 3 mm of tread, as some advise?
Many experts advise the exchange of tires as soon as the floor sculptures, which exist to drain the film of water that forms between them and the road, reach 3 mm deep. This is despite the fact that the legal minimum for driving on the public road is only 1.6 mm. Now Michelin has come to the public to draw attention to the fact that this is not only a mistake and a waste of money, it may even be giving up some tires in a state that is close to perfection.
The French tire manufacturer claims that if “all drivers followed the guidelines of most tire shops and changed them to 3 mm of the floor, they were spending another € 6.9 billion pounds per year than would be necessary”, Or even advisable from the point of view of safety. As if the additional money was not enough, the environmental impact has to be taken into account, as “changing tires before time implies consuming another 128 million tires per year, whose production leads to the release into the atmosphere of another 9 million tons of CO2 annually”, says Michelin.
Advising the advance exchange of rolling equipment is obviously advantageous for the companies that manufacture and market them, but it is bad for all the other stakeholders, and for the environment itself. According to the French brand, which in this way is putting the public interest above their own, this would be equivalent to “changing shoes when they just need to be cleaned, or throwing away the toothpaste when it is still halfway.”
Michelin also suggests that consumer groups conduct more comparative tests to prove that tires with less than 3 mm of tread are as safe as new tires. And he recalls that “good 1.6 mm tires are much more effective than low-cost new tires.”
Care should be taken not to let the depth of the sculptures fall below 1,6 mm, because not only will the efficiency not be the same, due to the risk of aquaplaning, but will have immediate costs if caught in a control of the authorities, as they are below what is permitted by law.
