Provided are: a tire reinforcing member in which reinforcing cords have both satisfactory rigidity and satisfactory fatigue durability; and a tire including the same. A tire reinforcing member (100) includes a rubber-cord composite formed by arranging one or plural reinforcing cords (101) in parallel and coating the reinforcing cords (101) with a rubber. The reinforcing cords (101) include hybrid cords in each of which a sheath portion (103) is formed by spirally winding plural non-metallic fiber cords (103a) composed of non-metallic fibers other than carbon fiber around a core portion (102) composed of a carbon fiber cord (102a), and the non-metallic fiber cords have a tensile elastic modulus of not less than 0.1 GPa at 25°C.
