Review of the Green Diamond Icelander MT

The Green Diamond Icelander MT is not your average mud terrain tire.  Several features that make up this unique tire set it apart from the rest of the MT tires.  Manufactured in the U.S.A. by Green Diamond Tires, the Green Diamond Icelander uses technology invented in the harsh conditions of Iceland to enhance an otherwise great performing offroad tire.  The most notable feature of this tire is a mixture of hard silicium carbide granules found in the tire tread.   The silicium carbide granules are found from just a millimeter below the initial new surface veneer to the last bit of tread on the tire carcass.  What does the hard silicium carbide granules do for traction?  Quite a bit according to users of the tires.  Most prominent, the carbide granules work like silent studs on all surfaces and terrains, increasing traction on otherwise slick surfaces such as ice, wet roads and rocks.  For this reason tires with this technology are popular in the frigid winter conditions of Iceland.  In the states, Green Diamond Tire produces remanufactured tire with this technology in many models to choose from in several popular sizes.  The Green Diamond Icelander MT is a Mud Terrain tire with an aggressive directional tread pattern designed to propel the vehicle through the deep mud, over rough and rocky terrain.  With 8 or 10 protective plys (model dependant), the Icelander performs very well in Mud with excellent self cleaning ability using multiple channels to move the mud away from the tire to find traction.  Although it's best traction will be found in it's forward direction, the tire also does well in the reverse direction of it's direction tread design.  Found down the center of the Icelanders tread design is a large stepped and staggered center void that helps to channel mud, water of whatever out through to it's voids running laterally towards the sides of the tire.  The staggered pattern outer lugs prove quite effective in scooping and moving mud, earth and snow, which equals forward momentum. 

The Icelander MT also provides excellent traction on rocks.  When aired down for offroad, the Icelander wraps well around rocks as the hard silicium carbide granules found in the tire tread provide tiny sharp edges of grip in the rock surface.  This feature is especially noticeable on wet rocks or where ice and snow may be present and affect offroad traction.

Most notable is the Icelander MT's performance on forested terrain trails where it excels in the variety of terrain obstacles found in these areas such as the their rocky terrain, mud, clay dirt, water crossings and under brush and moss of the forest trails. 

In sand the Icelander provides decent floatation.  When wheel spin is applied, the tread design will tend to dig as it is designed for excellent forward traction and self cleaning.

On the street the Icelander MT performs well and produces minimal road noise, even at highway speeds.  Traction on the paved surface improves as the hard silicium carbide granules found in the tire tread become exposed and compliment the tire tread compound.  As the tread compound wears, the hard silicium carbide granules are constantly renewed for the life of the tire.

Green Diamond Tires are available through distributors across the U.S. and from green Diamond Tire themselves.  Sizes are limited but the most popular sizes for general applications are available.  For more information contact Green Diamond Tire or visit their website.

Manufacturers Description of the Green Diamond Icelander MT and the process that makes up a Green Diamond Tire

Product development

Green Diamond Tires are an Icelandic invention. The patent for the production method is held by New Industries Ltd, of Reykjavík, Iceland.

In 1995 New Industries Ltd developed a highly sophisticated technique for mixing hard silicium carbide granules into the material compound of a tire tread. The now internationally patented production process is now at mass production levels for the Northern European market.

The patented technique is licensed for use by several progressive producers of tires in the manufacture of the Green Diamond Tire.

The high standards of performance of Green Diamond Tires are based on the thousands of small sharp-edged granules making firm contact with the icy road surfaces, giving them superior traction without the hammering and damaging effect of studded tires.

Green Diamond Tires eliminate the two serious drawbacks of studded tires, road wear and noise emission. This is achieved while maintaining control effectiveness in slippery conditions and prolonging the wear of the tire.

The success of Green Diamond Tires is confirmed in Iceland by a rapid increase in market share, reaching 10% for winter tires in competition with studded tires and other brands of winter tires.

In Sweden the production has increased from 3,000 tires in 1998-99 to 15,000 in 1999-2000 and is expected to exceed 70,000 in the 2006-2007 winter season.

What is a Green Diamond Tire?

In manufacturing a Green Diamond Tire, the granules are distributed evenly throughout the rubber. This infusion of the granules throughout the tire’s wear surface ensures that as the tire wears down and granules are worn away, new ones are uncovered. Green Diamond Tires are particularly suitable for use with vehicles equipped with anti-lock braking systems (ABS), with superior, scientifically-proven performance against any other tires with in the most difficult of slippery conditions, around 0°C.

Green Diamond Tires are environmentally responsible. Using only premium quality casings, each 'donor' casing is exhaustingly examined using sophisticated test and inspection instruments and equipment.

Use of Green Diamond Tires

Green Diamond Tires are produced in both winter patterns and all-season patterns (light truck only). For use in areas with heavy snow, the winter patterns are more suitable and for regions with less snow but more ice on the roads, all-season tread patterns are generally better suited.

Green Diamond Tires must be 'run-in' by driving 1,500 to 2,000 miles on clear, dry roads. It is during this driving period that the silicium carbide granules will begin to emerge. To protect the manufacturing equipment, Green Diamond Tires have a thin veneer of ungranulated tread rubber molded over the granules, which wears off in use.

As the Green Diamond Tire wears, some of the visible granules fall out of the tire and new granules appear.

This feature is a main benefit and attribute of Green Diamond Tires since the granules enhance the pattern as the performance of the pattern itself decreases with wear.

This applies particularly to studded tires; tests show that after 10,000 km on the road a studded tire has lost 85% of it's added properties.

Each Green Diamond Tire represents gallons of petroleum saved... and one less tire clogging a landfill.


Green Diamond Tires are good for the environment. Through a process called "Remolding" a tire is reused in the production of a Green Diamond tire.

Most of the natural resources are consumed in producing the body of the tire (steel belts, fabrics and bead bundles). Remolding technology reuses this expensive part of the tire and remanufactures it using 21st Century technology.

Casing Selection

Only premium quality tires can be used to make Green Diamond Tires. A thorough physical and electronic inspection ensures the integrity of the casing. Less than 5% of tires are suitable to be remanufactured into a Green Diamond Tire!

Computerized Balancing

Every tire is pre-balanced before being remolded. The data provided by the balancer is used in the remolding process to produce a tire that is in optimal balance.

Rubber Application

Using computerized digital photography, rubber is reapplied to the casing exactly as it was in the original tire.


The same presses that were used to create the tire originally are used to produce tires that have the same appearance and quality of the original tire.

Wear-in Period

The carbide bits must be covered over by a thin layer of rubber to prevent the molds from being scratched.  It takes as much as 2000 miles to optimally expose all the granules. During the first 2000 miles you still have as good of traction as any other tire could provide. 


To the right, a set of the Green Diamond Icelanders MTs are beginning to expose a few of the  hard silicium carbide granules after several hundred miles of highway driving.  In the near future Offroaders.com will go further in-depth with our test results both on and offroad with these tires.
