Tubeless tires for trucks and buses have radial carcass plies of polyester cords turned up around bead wires from the lateral inside to the lateral outside of the carcass walls. Polyester cords of not less than 4,500 d are used for the carcass plies. The compressibility of an inner-bead portion, i.e. that portion of the bead between the bead wire and a bead base is 4% to 35% of the entire inner-bead portion and 7% to 70% of the rubber material portion thereof. The most preferable compressibility is 15% to 20% as to the entire inner-bead portion and 30% to 35% as to the rubber material portion.
