Triangle TR643. FEATURES AND BENEFITS: Trailer tire, NOT FOR LIGHT TRUCKS; Enhanced controllability; All weather traction; . OVERVIEW: The Triangle TR643 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 model offers excellent all weather traction. The tread pattern and the all season tire compound improve the dry, wet and winter weather road gripping ability. The special tire compound maintains the tire's flexibility throughout the year, including in colder temperatures, while the symmetric design's elements find firm grip on the road surface in all conditions. The tread's circumferential grooves prevent hydroplaning by dispersing water and slush from below the tire's footprint. The improved road gripping ability and hydroplaning resistance to boost the year round driving safety.The tire's stronger internal structure and constant road contact increase the tire's controllability. The reinforced steel belt structure keeps the tire's optimal shape under the driving and load pressure affecting the model and actively resists deformation during the drive. The tread's continuous center rib closely follows the road surface and improves the steering response time and accuracy to the towing vehicle's instruction and stabilizes the tire's structure while it is in motion. The improved controllability ensures a safer ride and easier controllability, which makes the towing vehicle's job easier.The TR643 ensures a lengthened tread life. The symmetric tread design equally circulates the driving pressure along the tread area. The evenly spread out forces of acceleration, cornering and braking extends the tread life and the tire's usability by preventing irregular wear formations on the tread area. The longer lasting service life makes the model more cost efficient. Manufacturers recommend changing tires every 10 years. As long as tires are properly stored before they are sold, the year of their manufacture will not shorten their service life.
