Nitto Mud Grappler Extreme Terrain


  • Mud terrain traction
  • All weather traction
  • Enhanced load durability
  • Damage resistance
  • Upgraded controllability


The Nitto Mud Grappler Extreme Terrain is a mud terrain, all season tire manufactured for light trucks.

The tread design and all season compound increase all weather traction. The staggered tread elements enhance the number of biting edges gripping the road surface during the drive in dry, wet and winter weather. The tire compound manages to maintain the rubber flexibility in various temperatures. This combination ensures the tires exceptional year round performing safety.

The tread design also enhances the versatile terrain grip. The staggered tread blocks and the zigzag voids between the tread elements work together to increase the grip the tire has on off-road terrain surfaces. The aggressive tread pattern, in this manner, enables the tire to upgrade the soft, loose and uneven terrain gripping ability. These elements enable the tires forward motion on loose dirt and in deeper mud, allowing them to enhance its constant off-road performance. The tread also offers a superb self-cleaning ability. The tread elements eliminate mud and snow and eject rocks stuck between the tread elements. In this manner, the tire maintains the ideal surface contact as mud and snow do not cut off the tires surface contact, while it actively prevents stone retention from harming the casing by drilling rocks into the tread area. As a result, the tire ensures a safer driving experience.

The tires reinforced internal structure improves its load durability and damage resistance. The full steel belt structure keeps the ideal tire shape under the load and driving pressure affecting it. The stronger construction upgrades the load carrying and withstanding ability, which significantly upgrades the load capacity. The optimal ply structure, on the other hand, manages to protect the tire against off-road damage. The reinforced plies protect the tire from punctures, cuts and impact damage, which may shorten its usability and service life. The better and stronger structure, in this manner, protects the tire against any type of damage during its off-road performance.

The Mud Grappler Extreme Terrain increases the controllability. The tread design boosts the terrain surface contact throughout the tires performance. This enables the model to upgrade the steering responsiveness and the driving stability. The steering becomes faster and more precise in its response to the drivers commands, while the structure is stabilized against the driving pressure affecting the model. As a result, the tire ensures the drivers full control over the vehicle in all weather conditions on various terrain surfaces.

The intended purpose of Mud Terrain tire types is off-road use. They are not designed for regular highway driving.
