The invention belongs to the technical field of tire temperature testing, and particularly relates to a tire steady-state rolling temperature testing method, which is characterized in that a temperature label for measuring temperature and a positioning label for identifying the position of the temperature label are pasted in a vulcanized tire, the temperature label is a flexible ultrahigh-frequency high-temperature-resistant temperature measuring label with the frequency of 900Hz, and the positioning label is a flexible ultrahigh-frequency high-temperature-resistant temperature measuring label with the frequency of 900Hz. The passive radio frequency identification system is made of a flexible circuit board, can be prevented from being deformed and damaged in the tire forming and rolling process, is adhered to the interior of a tire through a high-temperature-resistant strong adhesive, can normally work within the temperature range of-40 DEG C to 200 DEG C, cannot be damaged under the high-temperature condition during vulcanization, and is high in safety and reliability through cooperative work of the two passive radio frequency identification systems. Testing the temperature of the rolling tire, calculating a temperature field of the tire during steady rolling through a numerical simulation technology, comparing a test result with a simulation result, and verifying the accuracy of the temperature test of the rolling tire; the principle is scientific and reliable, the test result is accurate, and the practical use value is achieved.
