Measurement of the vulcanization temperature of 14.00R20 cross-country radial tire was introduced. The temperature curve was obtained and then the cure degree of different parts of the rubber compound was calculated using rubber curing activation energy and measured temperature data. The results showed that the tire curing conditions and the cure degree of various parts were good. The middle part of the sidewall had the highest degree of cure, over 400%; and the tread shoulder had the lowest degree of cure, less than 100%.
