Kumho KRT03a. FEATURES AND BENEFITS: All season traction; Fuel-efficient performance; Enhanced controllability; . OVERVIEW: The Kumho KRT03a is a highway terrain, all season tire manufactured for commercial vehicles. This model was made for the vehicle's trailer axle.The model greatly improves the all season traction. The all season compound, with the heat-resistant rubber materials, and the symmetric ribbed tread design upgrade the dry, wet, and winter weather surface grip. These tread elements optimize road traction with the use of extra biting edges, while the compound optimizes the rubber flexibility in versatile temperatures. The ideal groove pattern disperses water and slush from the footprint, avoiding hydroplaning in the process. This results in a safer driving experience.A fuel-efficient performance is also ensured with the tread design and the tire compound. They optimize the traction and prevent heat build-up across the tread area. In this manner, the tire greatly decreases the rolling resistance while the tires are in motion. The rolling resistance is the pressure that determines the vehicle's needed fuel intake levels. Lowering the rolling resistance allows the tire to decrease the towing vehicle's fuel consumption and CO2 emission levels. This results in a fuel-conscious and environmentally friendly driving experience.The KRT03a boosts its controllability as well. The flat footprint and the wider rib pattern ensure close and consistent surface contact. This promotes the tire's great performing ability by enhancing the steering responsiveness and driving stability. The tire ensures an optimized steering response time and accuracy to the towing vehicle's instructions, while the structure is secured against the driving pressure. This results in a longer-lasting 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.
