PROBLEM TO BE SOLVED: To reduce the weight of an aircraft, to lessen the wear of a tire, and to prolong the service life of the tire. SOLUTION: Blades of a semi-spherical shape or an adequate shape which are rotated under the wind are fitted to a tire, a rim or both of an aircraft. The tire and the rim are fitted to the aircraft, in which wheels are rotated by the effect with the outside air when the aircraft lowers its landing gear, and rotated at considerably high speed when the aircraft is landing to reduce the friction and shocks when the aircraft lands.
