Summit Ultramax HP A/S 235/40R18, All Season, High Performance tires.

Features and Benefits: All season traction; Fuel-efficient performance; High speed controllability; Longer lasting usability; Summit Ultramax HP A/S TiresThe Summit Ultramax HP A/S is a high performance, all season tire made for passenger vehicles. Summit offers a 50,000 mile treadwear warranty with this model. The tire combines the all season compound and detailed tread design in order to promote excellent all season traction. The silica elements of the compound and the siping detail of the footprint enable the tire's performance in dry, wet, and winter conditions. As a result, the model's rubber flexibility is maintained, while the footprint grips the road surface. The tire's wider circumferential grooves prevent hydroplaning as they channel water and slush away from the footprint. The ideal year-round traction promotes a fuel-efficient drive. This traction helps to minimize the driving pressure placed on the tires during their performance. Therefore, it effectively reduces the rolling resistance. This is the pressure that determines the vehicle's needed fuel intake. By reducing it, the tire is able to minimize the vehicle's fuel consumption and CO2 emissions. The result is a fuel-conscious driving experience. The tread design's road contact and the heat-resistant compound optimize the high speed controllability. They maintain surface contact in order to upgrade the model's steering responsiveness and driving stability. This promotes quick and precise steering responses, while the structure is stabilized as well. On the other hand, this stability and the silica compound optimize the high speed durability. They prevent heat build-up and ensure the tire's exceptional performance, even at high speeds. The Summit Ultramax HP A/S promotes a lengthened tread life. The tread pattern's stability and the silica compound optimize the tread wear rate and manner. They ensure even pressure circulation, avoiding irregular wear formations. In this manner, premature wear is also avoided thanks to the silica compound's wear-resistant elements. Slow and even wear significantly upgrades the tire's overall service life. 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.
