PROBLEM TO BE SOLVED: To reduce road noise and improve comfortableness and operation stability by at least providing extended parts extending from bead parts to the inside in the width direction of a tire, and providing a mounting part to a wheel and a damper part connecting together the mounting part and the bead part on the extended part. SOLUTION: A tire 10 is provided with a tread part 11 having both end parts in the width direction, side wall parts 12 connected to both end parts in the width direction of the tread part 11, respective bead parts 13 connected to the respective side wall parts 12, and extended parts 14 extending from the respective bead parts 13 to the inside in the width direction of the tire. The each extended part 14 is provided with a mounting part 15 to a wheel 20, and a damper part 16 connecting together the mounting part 15 and the bead part 13. Hereby by tuning the spring constant in the vertical direction of the damper part 16, comfortableness can be improved. Further because the damper part 16 is flexible construction, the tread part 11 is hardly floated up from the ground surface, and improvement of road surface gripping property, restraint of rutting, and improvement of operation stability can be attained.
