Yokohama Geolandar X-MT


  • Mud terrain traction
  • Self-cleaning tread design
  • Enhanced durability
  • Longer lasting tread life


The Yokohama Geolandar X-MT is a mud terrain, all season tire manufactured for light trucks.

The tire increases the off-road terrain performance. The aggressive tread design, which extends to the sidewalls, improves the model's soft, loose and uneven terrain traction. These tread elements boost the grip on various terrain surface conditions. The staggered and stepped tread blocks, high void ratio and the sidewall blocks work together to ensure the tire's forward motion in deeper mud and loose dirt, preventing the tire from being stuck on the terrain due to lack of traction. The tread design's elements also keep the footprint clean. This tread pattern eliminates mud and snow and ejects rocks stuck between the tread elements. This prevents snow and mud from blocking the tire's surface contact, while it avoids stone retention, guaranteeing a safer off-road driving experience.

The durable structure and stronger compound enhance the tire's longevity. The reinforced geo-shield construction features a full nylon cover, a steel belt structure and a strengthened sidewall protection that work together to maintain the tire's ideal shape under the load and driving pressure affecting the model. The stronger construction also manages to protect the tire against the dangers of off-road driving. This also helps the tire to prevent damage to the casing. Punctures, cuts and impact damage are avoided in this manner with the reinforced internal structure. The tread's durable polymer compound slows the tread wear rate down. The polymer in the compound increases the tire's wear resistance, promoting a longer lasting tread life and usability.

The ideal tire shape enables the tire to keep its surface contact at all times. This increases the model's controllability. The better surface contact enables the tire to boost its steering responsiveness and driving stability in all weather conditions. As a result, the steering becomes faster and more precise in its response to the driver's commands, while the structure is stabilized against the driving pressure affecting the model. The ideal tread pattern and the durable compound work together to enhance the dry, wet and winter weather road gripping ability and power.

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

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.
