Smart-way Verified, the GT Radial GDR668 is sure to give you exceptional ware and longevity all in an open shoulder traction design!

A Closer Look:

• Designed for use on the drive axle of commercial trucks and buses in local and long haul applications
• Features an open shoulder design that reduces uneven wear for a longer tread life while also helping to lower rolling resistance for better fuel efficiency
• Stone ejectors within the grooves force rocks, stones, and other debris out of the tire for consistent traction and to protect the casing from damage
• Built with large tread blocks and extra siping that increase traction and grip in wet and light winter weather conditions
• Steel belted construction enhances strength and durability for a higher load carrying capacity, longer tread life, and extra stability

Tire features:

Open shoulder blocks help in loose soil by maintaining traction and even pressure distribution and resistance to irregular wear, lowering rolling resistance, and saving more fuel.

Stone ejectors in center grooves maintain casing integrity by reducing stone drilling.

Large tread blocks with siping increase the traction and grip in wet and wintry weather conditions.

Steel-belted internal construction designed for toughness and tire rigidity, reduced chance of deformation under heavy loads, providing stability and even wear.

GT Radial GDR668 Tire Review & Rating

The tire’s special wide-base design and its reinforced internal structure work together to enhance the load durability.

The all season compound and the ideal tread design improve the year round performing ability.

The tire’s symmetric ribbed tread block pattern with the siping placement upgrades the grip on the road surface. They provide additional biting edges in order to firmly grip the road surface throughout the year.

Furthermore, the stronger steel belt structure allows the tire to keep the ideal tire shape under the load and driving pressure. As the tire does not deform under the load and driving pressure, it is able to greatly boost the overall load and driving capacity.

The compound also keeps the rubber flexibility in versatile temperatures, optimizing the summer and winter weather performing capability.

The tread’s circumferential grooves prevent hydroplaning by dispersing water and slush from the footprint, resulting in a safer wet weather performance.

Overall Thoughts

The GT Radial GDR668 is a open shoulder drive position radial tire made for commercial trucks and buses, designed for long-haul applications.

Tire features: Open shoulder ribs help in long hauls by maintaining even pressure distribution and resistance to irregular wear, lowering rolling resistance, and saving more fuel.
