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

Summit Ultramax HP A/SFEATURES AND BENEFITS All season traction; High speed controllability; Longer lasting tread life; Fuel-efficient performance; OVERVIEWThe Summit Ultramax HP A/S is a high performance, all season tire manufactured for passenger vehicles. Summit offers a 50,000 mile treadwear warranty with this model. This tire promotes excellent all season traction. It combines the silica-based compound with a detailed directional pattern to enhance the tire's dry, wet, and winter weather performance. The sipe and groove placement generates a higher number of biting edges located across the tread area, while the silica elements of the rubber compound maintain their flexibility. This keeps the tire pliable in changing temperatures. Additionally, the circumferential grooves improve the hydroplaning resistance as they channel water and slush from the footprint. The solid center rib and the stable footprint ensure the tire's constant road contact. This effectively boosts steering responsiveness and driving stability at all times. The consistent surface contact provides faster and more precise steering responses and it also secures the tire's structure against driving pressure. Furthermore, the better stability and ideal structure optimize the tire's high speed durability. They keep the tire's shape, significantly improving its performance. The silica compound and ideal footprint stability help to enhance the tire's usability. The tread design's surface contact manages to evenly distribute driving pressure along the footprint. This effectively avoids irregular wear formations. On the other hand, silica elements in the compound decrease the tread wear rate, as they offer wear-resistant qualities. The slow and even wear greatly upgrades the overall service life. The Summit Ultramax HP A/S uses its silica compound and all season traction to lower its rolling resistance. They ease the pressure off the footprint, which in turn decreases the pressure that determines the vehicle's needed fuel consumption levels. Lessening the rolling resistance allows the vehicle to decrease its fuel intake and CO2 emissions, resulting in a fuel-efficient 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.
