By adjusting line periphery extruding amount of monofilaments having small twist or wave-shaped curves in advance and of at least one monofilament (111) of a 1n steel lines (110), at least one of sheath monofilament (212a-212i) of steel lines (210) having a m+n structure, or at least one of sheath monofilament (312a-312i) of steel lines (310) having a m/n structure, one can ensure that positions with a ratio L/d more than 0.7 do not exist at the whole monofilament perigon and more than two positions having a ratio L/d in the range of 0.07-0.7 exist at each space between twist helixes, whereinL represents a deviation amplitude between the track of monofilaments (111) which have been twisted up and have curves at a projection plane and a datum line of helix curve used in thread twisting, and d is a monofilament diameter. Therefore, rubber product reinforced steel cords exhibiting enough rubber accessibility and excellent fatigue resistance and tires for vehicles using said steel cordsare obtained.
