Sumitomo ST900

The all season compound and the optimal block placement increase the dry, wet and winter weather traction. The compound keeps the rubber flexibility in various temperatures by reinforcing the rubber compound elements. The larger tread block placement increases the grip on the road surface. The tread design's wide groove pattern and open shoulder placement upgrades the hydroplaning resistance by channeling water and slush from the footprint. In this manner, the tire guarantees a secure all weather performance.

The all steel casing manages to maintain the ideal tire shape under the load and driving pressure. As the steel casing does not deform under the pressure, it allows the tire to carry and withstand heavy loads throughout the performance. This construction also allows the tire to upgrade the surface contact during the drive. As a result, the tire manages to upgrade the steering responsiveness and the driving stability, increasing the driver's control over the vehicle.

The stronger compound protects the tire from tread damage. It reinforces the tire against tread chipping, cracking and tearing. On the other hand, the tread design's high void ratio manages to eliminate the rocks stuck between the tread elements. As rocks cannot lodge between the tread elements, it allows the tire to effectively prevent stone retention. The model's all steel casing protects the tire from punctures and impact damage as well. This prevents damage from causing the tire's downtime, optimizing the service life.
