Blackhawk BTR55ST. FEATURES AND BENEFITS: All weather traction; Enhanced controllability; Longer-lasting tread life; Improved load durability; . OVERVIEW: The Blackhawk BTR55ST is a highway terrain, all season tire manufactured for commercial vehicles. This model is made to be mounted on trailer axle positions.The model guarantees excellent all season performance. The tread design and the year-round compound boost dry, wet, and winter traction. The ribbed tread design is able to maintain consistent road contact, while the all season compound keeps the rubber flexible in versatile temperatures. Wide circumferential grooves disperse water and slush from the footprint and protect the tire from slipping in wet situations.The ribbed tread design and the durable compound offer great controllability. The tread design maintains road contact, boosting steering responsiveness and driving stability. The wide footprint offers stable performance and excellent maneuvering. The outer ribs firmly grip the road with the use of extra biting edges and upgrade the cornering ability. This tread design and stronger structure allow the tire's safe driving performance.The ribbed tread design and the durable compound protect the tire against irregular and premature wear along the tread area. The ribbed tread design is able to evenly distribute pressure across the footprint, while the durable compound slows the treadwear rate down. This combination significantly improves the tire's service life and usability.The Blackhawk BTR55ST also enhances load durability. The reinforced internal structure and the durable compound keep the ideal tire shape under load and driving pressure. The strengthened structure does not allow the tire to deform under load and driving pressure. This enables the tire to carry and withstand heavy loads under pressure, which boosts the overall load capacity. 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.
