Features and Benefits:
The GT Radial GDR668 is a highway terrain, all season tire manufactured for commercial vehicles. It is built to be mounted on drive axle positions.
Excellent year-round traction is guaranteed with this tire. The ribbed tread pattern keeps the road contact in summer and winter conditions, while the all season compound maintains flexibility in changing temperatures. This combination upgrades the tire's dry, wet, and winter-weather grip. On the other hand, the circumferential grooves prevent hydroplaning. They eliminate water and slush from the footprint and protect the tire against slipping on wet roads.
The model upgrades its controllability and driving stability. The ribbed tread pattern firmly grips the road surface with extra biting edges. This increases its contact with the driving surface for better steering responsiveness. The steering response time is faster and more accurate to the driver's commands. Driving stability is ensured as the structure is secured against driving pressure. Great cornering and maneuvering are boosted as well.
The tire provides a fuel-efficient performance. The ribbed tread design and the special silica compound ease the pressure off the tire. This allows the tire to minimize the rolling resistance, which is the pressure affecting the tire determining the vehicle's needed fuel intake levels. By lowering the rolling resistance, the tire manages to decrease the vehicle's fuel consumption and CO2 emissions, for a fuel-efficient and environmentally friendly driving experience.
Perfect load and driving durability are ensured with this tire. The strengthened internal structure and the special silica compound manage to keep the ideal tire shape under load and driving pressure. They enable the tire to carry and withstand heavy loads. As a result, this upgrades the tire's load-carrying capacity and handling power, which makes this model perfect for commercial applications.
The GT Radial GDR668 extends its service life. The model is able to prevent irregular and premature wear formations. In other words, this tread pattern evenly distributes driving pressure along the tread area, while the silica compound slows the treadwear rate down. This decreased and even wear guarantees a longer-lasting tread 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.
