Forerunner Mars B


  • Enhanced controllability
  • Mud terrain traction
  • Upgraded load durability


The Forerunner Mars B is a mud terrain, all season tire manufactured for ATVs and UTVs.

The tire offers excellent driving surface contact with the directional tread design. This pattern allows the tire to effectively optimize its steering responsiveness and driving stability. In other words, it ensures faster and more accurate responses to steering instructions. It also boosts structural stability throughout the performance. This combination enables the driver to effectively upgrade its overall controllability.

Aggressive tread elements upgrade the tire's off-road performance. The angled lug placement and the high void ratio work together in order to upgrade its soft, loose, and uneven terrain traction. These elements ensure consistent forward motion, while also offering better off-road durability. Excellent self-cleaning capabilities are also guaranteed. The high void ratio and open shoulder pattern prevent mud, snow, and rocks from packing between the tread elements. This optimizes the tire's surface contact, while effectively combating stone retention during the drive.

The Forerunner Mars B improves its load durability. It features a bias-ply structure that does not allow the tire to deform under load and driving pressure. In this manner, it is able to significantly increase the model's overall load capacity, resulting in a stronger performance.

This specific tire model features a BIASED ply construction.

When it comes to ATV tires, there might be slight visual differences between brands and models even if the tires are of the same size.

NOT FOR HIGHWAY USE: This tire model is not DOT-approved for highway use.

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.
