The present invention relates to a polyester tire cord made of polyester yarn and having a 5% LASE of 1.2 g/d or more as measured according to ASTM D885 at 80°C, a 5% LASE of 1.0 g/d or more as measured according to ASTM D885 at 120°C, and a toughness retention rate of 65% or more at 80°C and 120°C. The tire cord of the present invention has a modulus comparable to that of rayon even in a high-temperature environment at 120°C or higher, and has excellent dimensional stability and heat resistance, and thus it can be advantageously applied to a high-performance tire.
