PNEUMATIC TIRE

PROBLEM TO BE SOLVED: To provide a pneumatic tire favorably used as a tire for a racer, especially for a racing cart, assuring excellent maneuvering stability in the wet condition by securing a stable gripping performance able to work well with a wide condition about water quantity. SOLUTION: The pneumatic tire is structured so that its center region and shoulder regions are both free of main grooves having large width continued in the circumferential direction. Large width main grooves 2 in a bell shape are provided spreading approximately in a bell shape to the left and right approximately centering on the tire equator and having a specified inclination angle, groove width, and groove depth, in which main grooves 2 adjoining in the circumferential direction have a specified relation about the spacing d1 on the tire equator and the nearest land width d2 where the main grooves 2 approach to the nearest, and the negative rate of the center region is 50-80%.
