A pneumatic tire for off-road vehicles comprising a reinforcing element composed of helically formed filaments and having an excellent side-cut resistant property is disclosed. The tire is provided at its side portion with a side portion reinforcing layer composed of at least one rubberized layer containing a reinforcing element embedded therein and formed of a helically formed filament or a bundle of at least two helically formed filaments assembled together without twisting at random. The filament is formed of a material having a tensile breaking strength of at least 140 kg/mm.sup.2. The reinforcing filament has an elongation at tensile breaking strength which is 0.15 to 1.7 times that of organic cord of a ply of a carcass body. The rubberized layer containing said reinforcing element embedded therein as a whole is extensible.
