The elastic tie-down strap with snap hooks for attaching tire chains to tires is an elongated elastic member with an aperture in each of its two ends and a third aperture in its segment that extends between the two ends. Three snap hooks are coupled with the elongated elastic member via the apertures, with each snap hook passing through a separate aperture. When the snap hooks of a pair of the device are attached to points on a set of tire chains that is wrapped around a tire such that each elongated elastic member forms a two-legged angle with each leg stretched and in tension, the pair of the device secures the set of tire chains tightly to the tire. In an alternative embodiment, the elongated elastic member has just two apertures, one in each of its two ends with a separate snap hook passing through each aperture.
