The pneumatic tire of the present invention characterized by comprising a tread comprising two or more kinds of rubber components and a filler and having a volume of the low density region of 35% or more at elongation by an applied stress of 1.5 MPa, a volume of the void portion of 7.5% or less at elongation by an applied stress of 3.0 MPa and a filler distribution D represented by the following formula (I) of 2.0 or less and the crosslinked rubber composition of the present invention comprising two or more kinds of rubber components and a filler and having a volume of the low density region of 35% or more at elongation by an applied stress of 1.5 MPa, a volume of the void portion of 7.5 or less at elongation by an applied stress of 3.0 MPa and a filler distribution D represented by the following formula (I) of 2.0 or less are excellent in abrasion resistance. D = A 1 / B 1 / A 0 / B 0 In the formula (I), A 1 represents a volume fraction of a rubber component A in a filler gel, B 1 represents a volume fraction of a rubber component B in a filler gel, Ao represents a volume fraction of a compounded rubber component A, Bo represents a volume fraction of a compounded rubber component B.
