The Yokohama 121T is a highway terrain, all season tire manufactured for commercial vehicles, made to be mounted on the trailer axle.

The tire offers great all weather traction. The tread pattern and the durable compound increase the tire's grip in dry, wet, and winter weather. This allows the tire to securely perform throughout the year. The compound maintains rubber flexibility even in hot summer or cold winter weather conditions. The wide grooves disperse water and slush from below the tire’s footprint and avoid hydroplaning in wet and winter weather. This model ensures great year round driving safety.

The symmetric tread pattern firmly grips the road surface at all times. This allows the tire to evenly distribute driving pressure along the tread area. The special tread grooves lower the pressure affecting the tire. The tire’s rolling resistance is decreased, which deteriorates the energy needed to keep the tires in motion. The reduced rolling resistance lowers the vehicle’s fuel consumption, guaranteeing a fuel-conscious and environmentally-friendly performance.

The model improves its load capacity with its reinforced internal structure. The tire's strengthened structure increases the model’s durability. The structure maintains the tire’s ideal shape under driving and load pressure affecting the model. The strengthened construction allows the tire to carry and withstand heavy loads, which upgrades the model’s driving and load durability.

The Yokohama 121T is easy to control in all weather conditions. The symmetric tread pattern closely follows the road surface, which increases steering responsiveness and driving stability. This allows the tire to boost driving security and make the tire safer to use in different conditions.
