PROBLEM TO BE SOLVED: To provide a lug tire can improve vibration ride comfort performance especially during traveling on a good road without degrading traction performance. SOLUTION: A plurality of thin grooves 18 extending in a tire circumference direction are formed on a tread of a lug 14 in a tire width direction to reduce rigidity of the tread part of the lug 14, and to buffer rolling vibration during driving on a good road, thus improving vibration ride comfort performance. The vibration ride comfort performance can be improved without changing the shape of the lug 14, therefore, the original performance of the lug, that is the traction performance on a rough road, such as a field is not degraded.
