Disclosed is a radial tire for an automobile, in which lyocell having a dry/wet tenacity ratio S1/S2 of 1.2 to 1.6, a tensile strength at high temperature/a tensile strength at room temperature ratio S3/S4 of more than 0.8, and a shrinkage E of less than 0.01 is applied to a carcass part, thereby a resistance to fatigue and dimensional stability in running of a tire are improved.
