Tri-Ace Pioneer M/T


  • Mud terrain traction
  • All weather traction
  • Enhanced controllability
  • Longer lasting tread life


The Tri-Ace Pioneer M/T is a mud terrain, all season tire manufactured for light trucks. Tri-Ace offers a 45,000 mile treadwear warranty with this model.

The tire improves the mud terrain traction with the aggressive tread design. In other words, the staggered block pattern and high void ratio of the footprint upgrade the soft, loose and uneven terrain traction. These tread elements guarantee the tire’s forward motion at all times, ensuring its deep mud and loose terrain performance. The footprint allows the tire to improve the self-cleaning tread design as well. They disperse mud and snow stuck between the tread elements, preventing them from blocking the surface contact. They also avoid stone retention as rocks cannot drill into the tread area and harm the casing.

The all season traction is guaranteed with the all weather compound and the aggressive tread design. They work together to upgrade the dry, wet and winter weather surface grip. The compound keeps the rubber flexibility in versatile temperatures, while the compound keeps the rubber flexibility in versatile temperatures. This combination ensures the tire’s secure year round performance.

The model’s durability and controllability are also upgraded. The footprint’s stability ensures the tire’s surface contact at all times, which enhances the steering responsiveness and driving stability. As a result, the tire is quicker and more precise in its response to the driver’s commands, while the structure is secured against the driving pressure affecting the tire. The reinforced internal structure enables the tire to keep the ideal tire shape under the load and driving pressure. In this manner, the tire is able to greatly improve the load carrying ability, optimizing the load capacity at all times.

The Pioneer M/T promotes a lengthened usability. The stabilized footprint and the durable compound elements upgrade the tread life. The footprint allows even pressure distribution across the tread area, avoiding irregular wear formations. On the other hand, the stronger compound manages to minimize the treadwear rate. The reduced and even wear significantly enhances the overall service life.

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.
