Title: Tire

Description:
BACKGROUND OF THE INVENTION  
       [0001] 1. Field of the Invention  
       [0002] The present invention relates to vehicle tires and, more particularly, to a vehicle tire, which supports the tire for normal functioning for a length time when the tire damaged accidentally.  
       [0003] 2. Description of the Related Art  
       [0004] For a safety driving, the condition of vehicle tires must be regularly checked. There are two kinds of vehicle tires used in existing motorcars, namely, the tire having an inner tube, and the tire without inner tube. According to conventional tire designs, a meshed metal wire structure formed of transverse metal wires and a longitudinal metal wires is arranged in between the carcass and the tread. The two layers of metal wires are arranged at 17˜26°. This meshed metal wire structure can only reinforce the structural strength of the tire. It cannot protect the tire against piercing of an external sharp object. When a nail or the like pierced through the open spaces in the meshed metal wire structure, the tire leaks, and a tire explosion accident may occur.  
       SUMMARY OF THE INVENTION  
       [0005] The present invention has been accomplished to provide a tire, which eliminates the aforesaid problems. According to one aspect of the present invention, the tire comprises two inward lips respectively protruded from two opposite sidewalls of the body thereof at an inner side adapted for supporting the tire in shape when the tire damaged accidentally, the inward lips each having a corrugated bottom sidewall, two opposite lateral sidewalls, and a plurality of air holes transversely extended through the lateral sidewalls. The inward lips may be reinforced with reinforcing wires or the like.

     [0010]FIG. 5 is similar to FIG. 4 but showing air exhausted from the tire. 
    
    
     DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT  
     [0011] Referring to FIGS. from  1  through  3 , the tire  10  comprises two inward lips  101  respectively inwardly protruded from the two opposite sidewalls thereof. The inward lips  101  have a bottom sidewall corrugated, and a plurality of air holes  103  transversely extended through two opposite lateral sidewalls thereof that facilitate ventilation and diminish the weight of the tire  10 .  
     [0012] Referring to FIGS. 4 and 5, the tire  10  is fastened to a wheel rim  50 , forming with the wheel rim  50  a vehicle tire. In case the tire  10  exploded due to an accident, the inward lips  101  support the tire  10  in shape, enabling the car to be continuously driven to the repair shop safely to receive a repair.  
     [0013] It is to be understood that the drawings are designed for purposes of illustration only, and are not intended for use as a definition of the limits and scope of the invention disclosed.
