The invention discloses a groove bottom strengthened tire which comprises a tire crown, a tire sidewall, a tire bead and a tire tread, the tire tread comprises a central pattern block and shoulder pattern blocks, grooves are formed between the central pattern block and the shoulder pattern blocks in a staggered mode, the grooves comprise a plurality of circumferential grooves and a plurality of transverse grooves, the circumferential grooves are formed in the circumferential direction of the tire, and the transverse grooves are formed in the circumferential direction of the tire. The transverse grooves are formed along the width direction of the tire; and a wedge-shaped strip is arranged at the bottom of the groove and is made of a fiber reinforced composite material. Due to the design of the wedge-shaped strips, particles can be effectively prevented from being attached to the grooves in the tire tread, blockage and accumulation of the particles to the tire are avoided, and the risk of crack formation is reduced.
