Special-shaped inflation-free solid tire

The invention discloses a special-shaped inflation-free solid tire. The special-shaped inflation-free solid tire comprises a tire body and a plurality of special-shaped grooves, the special-shaped groove penetrates through the tire body in the axial direction, and the cross sectional area of the special-shaped groove in the axial direction is reduced from the two ends to the middle; the multiple special-shaped grooves are evenly distributed in the tire body in the circumferential direction. A plurality of through special-shaped grooves are formed in the tire body, the cross section areas of the special-shaped grooves are gradually reduced towards the middle, and the sizes of the special-shaped grooves are set, so that the deflection of the tire section under light load, heavy load or different road conditions during driving of the tire can be adjusted, and the driving comfort of the solid tire is basically consistent with that of a common pneumatic tire; the aging resistance is superior to that of other types
