N.J. Stat. Ann. § 39:3-73

Motor vehicle tires may be fitted with tire-chains of reasonable proportions when roads, streets and highways are slippery, because of rain, snow, ice, oil, manner of construction or other reason; provided, however, that no tire-chains shall be used at any time on improved highways when highway conditions do not make such use necessary for the safety of life or property. No person shall use any tire-chains so constructed or installed as to be likely to be thrown so as to endanger any person or property.
