Abstract: An agricultural tire includes a toroidal tire structure containing vulcanized rubber in an amount of about 90 percent or more by weight. The tire structure may have one or more performance enhancing features, including high strength plies. The high strength plies contain cords that are formed of yarns, including polyamide yarns, and have individual cord tensile strengths within a range of about 400 N to about 700 N. The performance enhancing features further include circumferential belt plies having cords at angles of about 74 degrees or more from an axial direction.

Abstract: A light emitting diode illumination system comprises a printed circuit board with score lines allowing a user to break the board into segments. The segments are a plurality of printed circuit boards provided with electrical elements. The electrical elements include light emitting diodes, a plurality of resistors and a zener diode. The zener diode has an associated capacitor and a plurality of associated rectifying diodes. The rectifying diodes convert AC to DC. Two pairs of electrical contacts are provided. Either pair is capable of coupling the electrical elements to a source of electrical potential to illuminate the light emitting diodes with minimum current while generating minimum heat.
