Barkley Trackstar UHP. FEATURES AND BENEFITS: Summer weather traction; Enhanced controllability; Upgraded driving durability; . OVERVIEW: The Barkley Trackstar UHP is a performance and high performance, summer tire made for passenger vehicles and SUVs. Barkley offers a 45,000 mile treadwear warranty with this model.The asymmetric tread design and the durable rubber compound improve the tire's overall controllability. These elements maintain constant contact with the driving surface and enhance the tire's steering responsiveness and driving stability. The tire's steering response time is faster and more precise to the driver's commands, while the structure is secured against the driving pressure affecting it. At the same time, the wide shoulder blocks boost the tire's cornering and maneuvering, while the special siping details shorten the braking distance by creating friction while stopping. These elements ensure the driver's full control over the vehicle and guarantee a safe driving experience.The model offers excellent summer weather traction. The asymmetric tread pattern and the summer compound enhance the tire's performance in dry and wet weather. In this manner, the ideal tread pattern closely follows the road surface in the summer season, while the special silica compound prevents heat build-up along the tread area in warmer temperatures. The optimized grooves effectively resist hydroplaning, by dispersing water from the footprint in wet-weather conditions.The Barkley Trackstar UHP provides great driving durability and handling power. The reinforced internal structure maintains the optimal tire shape under the driving pressure affecting it, while the special silica compound prevents heat accumulation along the tread area during the performance. This combination enables the tire to perform at its best high speed capability.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.
