PROBLEM TO BE SOLVED: To provide a vehicle tire change suitability reporting device superior in convenience.SOLUTION: In an exemplary embodiment of a vehicle tire change suitability reporting device, tire data on a tire 15 are input by an operation button. Accordingly, an ECU predicts a change destination load rate α of the tire 15, and compares it with an allowable load rate stored in advance, wherein the ECU corrects the allowable load rate on the basis of a vehicle weight of a vehicle 7 measured by a load sensor. When the change destination load rate α does not satisfy the allowable load rate as a result of the comparison in the ECU, the ECU calculates an adjustment air pressure &bgr; in the tire 15. The calculated adjustment air pressure &bgr; is reported to an operator or a driver via a display and a speaker. Furthermore, the ECU predicts a change destination speed when the vehicle travels by the tire 15, and calculates a speed difference with a reference speed. The ECU causes the display or the like to display a speed reflecting the speed difference. |
