K9 R-4 18X8.50-10

All Season

Tractor

N/A

The K9 R-4 is an all season tire manufactured for tractors. The model offers great performance on soft, loose, and uneven terrain surfaces, while keeping the footprint clean throughout the performance. The tread pattern manages to maintain surface contact at all times, which leads to better controllability and driving stability. The K9 R-4 enhances its load and driving durability, thanks to the reinforced internal structure and the durable rubber compound.

Versatile terrain traction


Improved controllability


Upgraded load durability

FEATURES

AVAILABLE SIZES

The large tread elements maintain surface contact at all times, even on soft, loose, and uneven surfaces. They firmly grip the surface with extra biting edges, maintaining forward motion. On the other hand, the model has a self-cleaning ability. It disperses mud, snow, and rocks stuck between the tread elements, boosting surface contact. At the same time, the stone ejectors eliminate stones and rocks from the tread, protecting the tire against stone retention.

The aggressive tread pattern closely follows the surface, which boosts steering responsiveness and driving stability. In other words, the steering response time is faster and more precise to the driver's commands, while the structure is secured against driving pressure. It also improves the cornering ability, which promotes a safer driving experience.

The strong structure and the rubber compound keep the optimal tire shape under load and driving pressure. They do not allow the tire to deform during the performance, which increases its load-handling ability. As a result, the tire carries large loads with ease, making it perfect for tractor application.
