National Duration EXE

FEATURES AND BENEFITS

• All season traction
• Enhanced controllability
• Longer lasting tread life
• High driving comfort levels

OVERVIEW

The National Duration EXE is a touring, all season tire manufactured for passenger vehicles and SUVs. It has some high performance tires as well. National offers an 85,000 mile treadwear warranty with T speed rated sizes, a 65,000 mile treadwear warranty with H and V speed rated sizes, and a 50,000 mile treadwear warranty with W speed rated sizes.

The model's all weather traction is optimized. The all season compound and the ribbed tread design improves the dry, wet, and winter weather grip. The stronger compound blend allows the tire to enhance the rubber flexibility at all times, while the sipe and notch pattern firmly grips the road surface with extra biting edges. The circumferential grooves disperse water and slush from the footprint, which effectively avoids hydroplaning in the process.

The asymmetric ribbed tread design and the flat footprint improve the surface contact as well. These tread elements enable the tire to enhance the surface contact at all times, increasing the steering responsiveness and driving stability. In this manner, enhancing the steering response time and accuracy to the driver's commands, while the structure is secured against the driving pressure. The shoulder block pattern with the sipe and notch pattern allows the tire to improve the cornering ability. They generate additional grip on the road surface, upgrading the cornering and maneuvering capability.

A lengthened usability is improved with the tread design and durable compound. The stabilized tread elements allow the tire to greatly upgrade the rubber flexibility at all times, optimizing the pressure circulation across the tread area. This effectively avoids irregular wear formations throughout the performance. The stronger compound allows the tire to greatly decrease the treadwear rate. The reduced and even wear significantly upgrades the overall service life.

The Duration EXE greatly decreases the road noise levels. The stabilized tread design and the close road contact enables the tire to greatly improve the quiet performance. These tread elements enable the tire to reduce the road noise heard by the passengers. The tire improves the passengers' driving enjoyment, as the road disturbances do not reach the vehicle's cabin. This offers a quiet and comfortable 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.
