Petlas Imperium PT515. FEATURES AND BENEFITS: Summer weather traction; Enhanced controllability; Longer lasting tread life; High driving comfort levels; . OVERVIEW: The Petlas Imperium PT515 is a performance, summer tire manufactured for passenger vehicles. This model has touring sizes available as well.The tire promotes exceptional summer weather traction with the summer compound and asymmetric tread design. Their combination allows the tire to significantly enhance its gripping ability on dry and wet surfaces. This is achieved thanks to the better road-to-rubber ratio of the footprint and the lateral groove placement, which provide the necessary traction. On the other hand, the durable compound effectively prevents heat accumulation along the tread area. Circumferential grooves evacuate water from the footprint, ensuring the tire's road contact even in wet conditions. This actively combats hydroplaning.Exceptional controllability and maneuvering are promoted as well. The asymmetric ribbed footprint closely follows the road surface at all times, optimizing its steering responsiveness and driving stability. This promotes a quick and precise steering response while securing the model's structural stability. The shoulder pattern and lateral groove placement generate friction while braking. This friction determines the tire's stopping capability. Better braking friction significantly shortens the vehicle's stopping distance.The tread design and summer compound also work together to boost the model's service life. The consistent surface contact and the stiff shoulder blocks manage to prevent tread flexing. As a result, excess pressure is not placed onto the tread area, which allows the tire to evenly circulate driving pressure across the footprint. The heat-resistant compound also avoids pressure accumulation, optimizing the tread wear rate. This guarantees slow and even wear, boosting the usability.The Imperium PT515 also promotes high driving comfort levels. The computer-optimized block array of the shoulders helps to reduce road noise generated. While the tires are in motion, the tire prevents road noise levels from reaching the vehicle's cabin. As they cannot disturb the passengers, they guarantee a quiet driving experience. 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.
