Patent ID: 7680610

Claim:
A tire abrasion predicting method for predicting an abrasion characteristic of a tire by calculating a tire sliding amount at a slip ratio applied to the tire rolling on a road surface so as to form a sliding region on a contact patch, the method including the steps of: acquiring a characteristic curve of a tire axis force exerted on a tire rotation axis at the slip ratio applied to the tire, the tire axis force being changed depending upon the slip ratio; deriving values of tire dynamic element parameters for determining the characteristic curve from the characteristic curve based on a tire dynamic model constituted by the tire dynamic element parameters; calculating a tire sliding amount based on a sliding region, the sliding region and an adhesive region, which are formed on the contact patch of the tire at the applied slip ratio, being calculated by applying the values of the tire dynamic element parameters to the tire dynamic model; and predicting an abrasion characteristic of a tread part of the tire at the applied slip ratio by using the tire sliding amount in combination with abrasion characteristic data of a tread rubber of the tread part.
