A cord for reinforcing tires, in particular tires, comprising a cellulose multifilament yarn is disclosed, wherein the cord has a strength of at least 35 cN / tex and the individual filaments of the multifilament yarn have a strength of at least 2.3 dtex And has a linear density. In use, such codes exhibit significantly improved fatigue behavior - that is, significantly higher fatigue resistance - than standard codes with individual filament linear densities between 1 and 2 dtex.
