Sumitomo ST709
FEATURES AND BENEFITS
- All weather traction
- Longer lasting tread life
- Enhanced durability
OVERVIEW
The Sumitomo ST709 is a highway terrain, all season tire manufactured for commercial vehicles. It was made to be mounted on the vehicle in all axle positions.
The tire improves the all weather traction. The symmetric ribbed tread design and the all season tire compound boost the dry, wet and winter weather traction. The symmetric pattern's firm road grip upgrades the number of biting edges gripping the road surface, while the compound increases the rubber flexibility in various temperatures. The groove pattern avoids hydroplaning, as the wide grooves disperse water and slush from below the footprint. This combination increases the year round driving safety levels.
The model extends the usability. The tread's ribbed pattern maintains the surface contact and allows the model to evenly distribute the driving pressure along the tread area. The equally spread out forces of acceleration, cornering and braking actively avoids irregular wear formations across the tread area. The durable tire compound manages to decrease the tread wear rate with the reinforced rubber materials. This enables the tire to significantly lengthen the usability and tread life.
The ST709 boosts the durability with the four steel belt construction. This maintains the tire's ideal shape under the load pressure and reinforces the tire against external damage. By preventing the tire's deformation, this structure boosts the load carrying ability and power, which increases the load capacity. The structure also resists punctures, cuts and impact damage which can shorten the tire's service life. The optimal tread design's stone ejecting elements protect the tire against stone retention as they eject rocks stuck between the tread area. This greatly heightens the driving safety levels.
