Sumitomo ST520

FEATURES AND BENEFITS

• All weather traction
• Damage resistant performance
• Enhanced controllability

OVERVIEW

The Sumitomo ST520 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 tread design and the all season compound improve the all weather traction. The symmetric ribbed pattern improves the grip on dry, wet and winter weather conditions. The optimal block placement and the ideal surface contact improve the grip on various terrain surface conditions. The durable tire compound keeps the rubber flexibility in various temperatures, from the heat of summer to colder winter conditions. The tread's wider zigzag circumferential grooves prevent hydroplaning by dispersing water and slush from below the footprint, maintaining the tire's surface contact and enhancing the driving safety levels.

The model features a four steel belt reinforced construction. This allows the tire to maintain the ideal tire shape under the load and driving pressure affecting the model. In this manner, the tire is able to carry and withstand heavy loads with ease, which significantly improves the load capacity. The strengthened structure also stabilizes the tire during its performance against the driving pressure. This helps improve the steering responsiveness as well, enhancing the tire's controllability in all weather.

The ST520 offers great damage resistance. The stone retention prevention of the tread's self-cleaning nature prevents rocks from drilling into the tread area and harming the casing during their performance. The reinforced compound, on the other hand, avoids the tread's chipping, cracking and tearing, while also protecting the tire from cuts and punctures. The strengthened internal structure further improves the puncture resistance, allowing the tire to securely perform. As a result, the tire extends the usability and tread life by promoting great durability.
