Hankook Ventus S1 EVO2 SUV HRS. FEATURES AND BENEFITS: Summer weather traction Alignment indicators Longer lasting tread life High speed controllability Run flat tire model. OVERVIEW: The Hankook Ventus S1 EVO2 SUV HRS is a high performance summer tire manufactured for sport utility vehicles (SUVs).The tire was made with the Hankook Runflat System, or HRS for short. This technology enables the tire to be driven on for 50 miles up to 50 mph in case of air pressure loss. As a result, the tires limited temporary performance is ensured after air pressure leaves the tire due to a puncture or other damage. This prevents the vehicle from being stranded on the side of the road, instead it can be driven to a nearby location where the tire can be fixed or changed. These tires cannot be mixed regular tires on the same vehicle, due to their heavier construction.The tire offers exceptional summer weather traction thanks to variable factors. The cooling system and the intercooler prevent heat retention that can deform the tread area. They achieve this by controlling excessive heat build up. The silica-based tire compound improves the wet weather road gripping ability, along with the aqua driving controls water dispersing ability, which prevents hydroplaning. The tread pattern provides great gripping ability in dry and wet weather conditions. These factors working together offer a safe driving experience in the hot summer temperatures, but the tire is not suited or safe to be driven in winter weather.The silica-based tire compound lowers the rolling resistance, which in turn lowers the fuel consumption of the vehicle and takes the driving pressure off the tire, providing a longer lasting tread life. The longer tread also wears evenly thanks to the alignment indicators. The alignment indicators are present parallelly on both shoulders of the same tire in different places. They wear with the tread and indicate whether the vehicles alignment is correct or not. If the two parallel symbols wear in the same manner, the alignment is good, if not then it needs to be fixed before the tires develop an irregular tread wear pattern. This enables the driver to check their tires regularly and prevent uneven wear, which lengthens the tread life and usability.The model is easy to control in all summer weather conditions thanks to its great stability and steering responsiveness. The high stiffness bead filler and the wide steel belt layer increase the tires driving stability and steering responsiveness by maintaining constant road contact. They keep the tire on the road in both dry and wet situations. The tire is quick and accurate in its response to the drivers commands and it allows the driver to confidently control the tire in all weather conditions. It also provides excellent uniformity and high speed durability. The strong single strand bead wire prevents deformation under the high speed driving pressures, enabling the tire to perform to its highest capability.The Ventus S1 EVO2 SUV HRS provides a superb performing ability. Firstly, its performing ability stays the same, even when the tire is wearing out. This is due to the triple driveline groove feature that maintains the tires excellent performing ability with the tread wear. Secondly, the tires high-density rayon and polyester carcass increases the tires durability. As the tire does not deform under the driving pressure, it is capable of safely performing at high speeds.
