Abstract
A pneumatic tire comprises circumferential main grooves extending in the tire circumferential direction and land portions defined by the circumferential main grooves. The land portions are each provided with a plurality of groove units which are sets including a first groove, a second groove, and a third groove. The first groove, the second groove, the third groove are disposed without meeting one another, and radially extend at intervals from each other ranging from 90 degrees to 150 degrees. Additionally, the first groove is a lug groove with the groove width ranging from 1.5 mm to 4.0 mm and has a semi-closed structure, opening to the circumferential main groove or the tire ground contact edge at a first end portion and terminating within the land portion at a second end portion.
