The recommended useful life of a tyre is six years and the recommended maximum age is 10 years.
The manufacture date is located on the sidewall of the tyre, displayed as a four-digit number; the first two are for the week and the last two for the year. For example “1117” means the tyre was manufactured in week 11 of the year 2017. Note: It is more important to pay attention to the wear and con…
An easy way to measure the groove depth is to use a two-euro coin: place it in the main groove in the central part of the tread. If the silver edge of the coin is still visible from within the tread, the depth is less than 4 mm.
Over time, the rubber compound in a tyre’s tread becomes harder, especially when exposed to heat and sunlight.
While the law does not define tyre life or stipulate manufacturing dates, tyres can only be considered and sold as “new” if they were manufactured within the last five years. The recommended useful life of a tyre is six years and the recommended maximum age is 10 years.
It is important to “break in” new tyres for around 500 kilometers (equivalent to almost a tank of gas), by avoiding quick acceleration, breaking and turning.
Used tyres cannot be taken to a landfill; they must be disposed of at an appropriate recycling facility. In Europe It is free to recycle old tyres because the price of new tyres includes a recycling fee.
New tyres have a groove depth of over 8 millimeters, though often more than 9 millimeters.
