Prometeon expands Pirelli Serie 02 commercial tyre range with H02 Pro Trailer

New European trailer tyre offers range of improvements impacting operating costs

Prometeon has expanded its Pirelli Serie 02 line of commercial vehicle tyres with the addition of a new trailer tyre designed for use on articulated trailers and suited to vehicles carrying particularly large loads and volumes over long haul routes. The Pirelli H02 Pro Trailer is available now in Europe and Turkey in sizes 435/50R19.5 and 445/45R19.5. The specialist commercial tyre manufacturer says the tyre offers a blend of excellent fuel economy and optimised operating costs, helping it to excel on long routes and motorway journeys. The tyre supersedes the previous ST:01 Neverending Super Single, offering all-round improvements, especially in rugged performance, safety, and load capacity.

“Thanks to the investments we have made in R&D over the last two years, the overhaul of the range and the introduction of the new Serie 02 lines will only accelerate in 2023,” explains Alexandre Bregantim, chief technical officer of Prometeon Tyre Group. “Our goal is always to provide our customers with products that offer cutting-edge performance.”

The H02 Pro Trailer range benefits from the Serie 02 Prometeon Engineered technological innovations. It has been designed to offer the highest levels of efficiency and optimised operating costs. It offers new standards of safety and load capacity, and a fuel consumption category which is now Class A for the 435/50 and Class B for the 445/45.

Compared to the previous range, Prometeon data shows the tyre offers improved safety, with 20 per cent greater wet grip performance and Three Peak Mountain Snowflake approval. Load capacity is increased by 10 per cent, at up to 10 tonnes per axle. The new tyre also offers a 20 per cent reduction in rolling resistance, meaning lower fuel consumption. The tyre is also manufactured to streamline fitment operations.

Prometeon says the Pirelli H02 Pro Trailer offers “best in class” performance characteristics versus competitor products. The H02 Pro Trailer in size 435/50R19.5, for example, offers leading EU tyre label ratings in its class for fuel consumption, wet grip performance, and external rolling noise, Prometeon states. The 445/45R19.5 size’s improved load index (up from 160 to 164) also leads its class, the manufacturer adds. It claims the tyre is the only model among its premium competitors with the 3PMSF marking and RFID sensor features. Prometeon’s Pirelli Serie 02 commercial vehicle tyres also benefit from approval from the major European vehicle manufacturers.

Prometeon says a range of its latest tyre technology innovations have helped to distinguish the H02 Pro Trailer. These include:

• SWITe (Spiral Wire Technology) – The cable of the zero-degree spiral belt has a new geometry and an increased diameter, promoting durability and resistance
• HR4B (High Resistance 4 Belts) – Belt configuration designed to maximise the flexibility and structural strength of the casing, helping to improve handling, durability and retreadability
• SHTB (Super High Tensile Belt) – Cords are made with high-strength steel, providing high flexibility and preventing propagation of corrosion, ensuring the integrity and longevity of the casing
• COBe (Cross Over Bead) – The reinforced bead, in combination with the new geometry of the metal threads, provides great flexibility, strength and high load capacity
• DLTC (Dual Layer Tread Compound) – The outer layer provides high mileage, excellent road-holding and shortened braking distances; the inner layer helps limit heat build-up and provides lower rolling resistance with greater tread integrity.

These technical features combine with the new tread pattern to help the latest product to offer high standards of efficiency in fuel economy, safety and load capacity.

Prometeon explains that the H02 Pro Trailer features six longitudinal grooves to encourage even wear, with the two outer ones larger to ensure efficient drainage of water and better driveability; the four central grooves are narrower to increase tread rigidity and guarantee the maximum mileage and lowest fuel consumption, without performance compromises in the wet.

The ribs feature special cylindrical ducts’ which promote stability and braking in the wet, while the central grooves feature variable geometry to offer excellent wet handling throughout the tyre’s lifespan, with reduced noise for improved acoustic comfort outside the vehicle.
