A tire load estimation device includes: acceleration sensors; a total vehicle weight calculating device; an acceleration waveform extracting device; a differential acceleration waveform calculating device; a peak position detecting device detecting peak positions on leading and trailing edge sides in the differential acceleration waveform; a ground contact time ratio calculating device calculating ground contact and rotation times from the peak positions to calculate a ground contact time ratio; and a lord estimating device estimating the load acting on the tire from the ground contact time ratio of each tire, a maximum load capability of the tire, the total vehicle weight, and an inclination obtained in advance by approximating a maximum load capability ratio, which is a value obtained by normalizing the load with the maximum load capability, with a linear function of the ground contact time ratio.
