The invention discloses a tire pressure alarm method, a tire pressure alarm device and a vehicle, the vehicle includes N groups of tires, the tire pressure alarm method comprises the following steps: step 1, starting to run the vehicle; step 2, detecting respective real time circumference value of the N groups of tires; step 3, comparing the real time circumference value of the NO i group of tires with the real time circumference value of the NO j group of tires; step 4, when the real time circumference value of the NO i group of tires is less than 90% of the real time circumference value of the NO j group of tires, sending a tire pressure alarm signal, otherwise, repeating the step 2 to the step 4, wherein i = 1, 2,... , N, j = 1, 2,... N, and i is not equal to j. Through the technical proposal, tire pressure situation can be judged by use of a current detection device of the vehicle, the current device on the vehicle can be fully used, the control method is simple, cost is low, reliability is high, and vehicle safety accidents can be prevented.
