The present invention relates to an apparatus and a method for measuring the abrasion of a tire using electric resistance of a tire tread, which can measure the abrasion of a tire by using changes in an electric resistance value changing in accordance with the abrasion of the tread of the tire. In accordance with the present invention, the apparatus for measuring the abrasion of the tire using the electric resistance of the tire tread comprises: a resistance measuring unit (31) which measures the electric resistance value; a connection unit (32) which electrically connects the resistance measuring unit (31) to an axle (22) with a tire (11) to be measured that is installed thereon; a grounding unit (33) which electrically connects the resistance measuring unit (31) to a road surface; and a control unit (51) which compares the electric resistance value (R) measured by the resistance measuring unit (31) with an abrasion reference value (B) of the tread, and when the electric resistance value (R) is less than the abrasion reference value (B) (R < B), determines that the tread of the tire (11) is worn out to the degree where the tire (11) needs to be replaced.
