Pirelli ST55 285/70 R19,5 150/148J

The Pirelli ST55 summer tire is specially designed for use on trailers and semi-trailers. Tires in this category must have increased reliability and maximum protection, as they are subject to constant maximum loads. In the development of this model, only high-quality, state-of-the-art materials and the most advanced technologies were used, which is why the model has excellent operational characteristics.

Special rubber compound

When creating the Pirelli ST55 tire, a unique rubber compound was used, which made it possible to increase traction and reduce tread wear during operation. And the use of two layers of rubber with different properties helped to achieve an optimal combination of increased wear resistance and maximum reliability, excluding the possibility of overheating the rubber.

Tread

The use of three central rows of continuous blocks has made it possible to increase the contact patch, providing excellent directional stability. Continuous blocks in the shoulder area perfectly protect the tire from possible cuts and damage. Four wide longitudinal grooves quickly remove water from the tread, ensuring a minimal aquaplaning effect. To increase the strength of the tread, in addition to using a special rubber compound, a high-strength cord was used. Therefore, the tire perfectly withstands constantly arising increased loads. Also, when creating the model's carcass, a reinforced ring was used, which made it possible to significantly increase the tire's strength, excluding the possibility of carcass rupture.

The tire is produced on modern equipment and undergoes thorough electronic and visual quality control, which completely eliminates the possibility of a defective batch entering the market. As a result, the tire enjoys well-deserved popularity among consumers and currently has an optimal price/quality ratio, outperforming many competitors in many parameters.
