Duro HF215 ZigZag. FEATURES AND BENEFITS: Trailer tire model; All season traction; Heavy-duty controllability; Longer lasting tread life; . OVERVIEW: The Duro HF215 ZigZag is a highway terrain, all season tire manufactured for trailers. This tire is NOT MEANT TO BE MOUNTED ON LIGHT TRUCKS, as its construction will not support the weight and performing style of such vehicles. It can ONLY BE MOUNTED ON TRAILERS.The tire improves the all season traction. The all season compound and the ribbed tread design greatly upgrade the dry, wet, and winter weather surface grip. The tread elements improve the grip the tire has on versatile surface conditions, optimizing its secure year round performance. The durable compound allows the tire to increase the summer and winter weather traction. The compound keeps its flexibility, ensuring a secure driving experience. Additionally, the zigzag groove pattern avoids hydroplaning by dispersing water and slush from the footprint, ensuring a safer wet weather performance.The ribbed tread design also ensures the tire's surface contact while the tires are in motion. The flat footprint enhances the tire's consistent road contact, in order to upgrade the steering responsiveness and the driving stability. This allows the tire to enhance the steering response time and accuracy to the driver's commands, while the structure is secured against the driving pressure affecting the tire. The reinforced internal structure with the bias plies improves the tire's load capacity. As the tire does not deform under the load and driving pressure. As a result, the model greatly upgrades the load capacity.The HF215 ZigZag enhances the length of the tread life. The ribbed tread design and the durable compound promote a longer lasting usability. The tread design and the flat footprint ensure even pressure circulation across the tread area, avoiding irregular wear formations. The stronger compound allows the tire to reduce the tread wear rate. The decreased wear upgrades the tire's service life. This specific tire model features a BIASED ply construction.
