Abstract
A method is provided for reading data relating to a tire, in which the data is stored in an electronic device integrated into the tire, and in which the tire is identified by a serial number and a manufacturing week number. A storage unit of the electronic device includes a data storage zone having a storage range formed of a number of bits. The storage range is also referred to as a restricted range, and the number of bits of the restricted range is less than or equal to 38. According to the method, the data stored in the restricted range is read, and the data read from the restricted range is decoded in order to determine the serial number and the manufacturing week number of the tire.
