The Mastertrack UN-203 is a highway terrain, all season tire manufactured for special trailers. This tire is not meant to be used on light trucks. The tread design and tire compound firmly grip the road surface and enhance the traction in dry, wet and winter weather. The ribbed tread design enhances the steering responsiveness to the towing vehicle, and stabilizes the tire structure to increase its ability to be towed. The UN-203 has excellent durability with the strengthened internal structure that maintains the optimal tire shape.
