Car Tyres

Pirelli is one of the most sustainable manufacturers of car tyres, with two outstanding products: the CinturatoTM P7TM Blue and the Winter SottozeroTM 3.

With the CinturatoTM P7TM Blue, Pirelli is the first tyre maker in the world that offers a tyre carrying a double A rating for certain sizes on the Eurolabel scale. According to its size, this tyre is sold either with a double A class rating or a class B rating for rolling resistance, while all sizes have an A rating for wet grip. On average, the CinturatoTM P7TM Blue guarantees 23% less rolling resistance compared with the Pirelli benchmark (class C rolling resistance), and thus lower fuel consumption and noxious emissions.

Here is a concrete example: a sedan equipped with the CinturatoTM P7TM Blue tyre that travels 15,000 kilometres a year consumes 5.1% less fuel, equal to 52 litres of fuel, and reduces greenhouse gas emissions by 123.5 kilograms of CO2. Its braking distance on wet surfaces is 9% less than the Pirelli benchmark (class B for wet grip) in the same segment. Moreover, the comparative tests by TÜV SÜD show that at a speed of 80 km/h on wet roads, P7TM Blue reduces braking distance by 2.6 metres as compared with a class B tyre. The CinturatoTM P7TM Blue has been developed for medium-high powered engines, as further evolution of the CinturatoTM P7TM, the most famous Pirelli Green Performance tyre presented in 2009. The evolution of the Cinturato line became necessary to meet drivers’ growing need for safety and economy. The CinturatoTM P7TM Blue is sold only on the replacement market, unlike the CinturatoTM P7TM, which is sold mainly through the original equipment channel.

This latter model has taken just a few years to become the benchmark tyre for the most prestigious car makers in the sedan, coupé and medium-high powered sedan segments.

In March 2013 the Winter SottozeroTM 3 tyres were presented in a preview offered to over 400 European dealers in Austria, between Seefeld and the Kühtai pass at over 2,000 metres. The third generation of ultrahigh performance tyres for the winter season, it was conceived to equip sports cars and powerful sedans and offer maximum grip on water, ice and snow. Here are the principal characteristics of this new product line:

  • an innovative compound made of functional polymers (that improve the mechanical, thermal and dynamic properties of the compounds), improving tyre performance;
  • an improved profile to guarantee greater mileage through uniform contact with the ground;
  • more ground contact for better road hold, rendered possible by tbe Lamella 3D.

In its Industrial Plan 2013-2017, Pirelli has undertaken to reduce the average rolling resistance of its own products by 40% from the 2007 average.

Truck Tyres

LThe R&D objective for the Truck Business Unit is to strike the greatest possible balance amongst the top characteristics of a tyre: performance, safety and respect for the environment. In other words this involves reducing its overall environmental impact while remaining focused on improving the product’s performance.

From the design stage on, Pirelli takes account of all product use conditions, including abnormal ones. This permits the development of tyres that do not stop at compliance with legal regulations, but have all the characteristics necessary to guarantee complete safety, both for the customer and for the environment, in accordance with the highest Pirelli product standards.

Numerous eco-compatibility features characterise the new generations of Pirelli truck tyres, beginning with the reduction in weight that in turn reduces both the quantity of raw materials used and energy needed to produce them. Furthermore the reusable materials that are employed and their durability are reflected in the duration of the “first life” of the tyre and the number of times that the same casing can be used for retreading the tyre.

The Serie 01 is the green performance range of tyres for industrial vehicles, launched by Pirelli in 2009. The Serie 01 tyres share the latest generation SATT™ structure, the most advanced for production of truck tyres, and constitutes the basis for lengthening product life, elevated rebuildability, extremely regular wear and tear, and better driving precision. Compounds and tread patterns are designed and optimised according to the performance requested for different uses. All Serie 01 product lines bear the Ecoimpact mark, which translates into:

  • high mileage and uniform tyre tread wear, through the use of high specific yield compounds, the SATT (Spiral Advanced Technology for Truck) structure, and an optimised tyre tread profile;
  • low rolling resistance (already in compliance with 2016 regulatory limits) and consequent reduction in fuel consumption and CO2 emissions;
  • highly retreadability, construed as the greater residual durability at the end of the tyre’s first life thanks to the new SATT structure combined with compounds having low hysteresis (i.e. generating less heat), with the hexagonal flush ring and reinforced bead;
  • low noise, construed as quiet ride and driving comfort, consistent with European regulations governing noise limits.

The ST:01™ Neverending Energy™ stands out among the top products. Developed specifically for equipping trailers and semi-trailers, ST:01™ Neverending Energy™ is the first line of truck tyres to be awarded the double class “A” of the European label, and thus both for rolling resistance and grip on wet roads. Like all the new Pirelli product groups, ST:01™ Neverending Energy™ also aims at maximum fuel consumption efficiency. There are considerable benefits for the fleet, considering that in a vehicle made up of a traction engine and semi-trailer the tyres fitted on the latter have 50% impact on the rolling resistance generated by all the tyres. The ST:01™ Neverending Energy™ line combines safety with energy saving (generating lower emissions), maintaining high performance in terms of mileage and durability, typical of a truck tyre. The benefits of the ST:01™ Neverending Energy™ line are made possible by:

  • an innovative tread pattern;
  • a tread compound with dual-layer technology with high silica content that reduces rolling resistance and thus fuel consumption, as well as ensuring improved resistance to tearing and higher mileage;
  • a new profile and different shape of the sidewalls and bead.

The product line dedicated to the medium and longdistance transport segment has also been rounded out by a new tyre that enhances safety and minimises operating costs, by means of energy efficiency, high mileage, possibility of reconstruction, reduced noise and use of innovative materials. With the new ST:01™ Base™ – characterised by innovative materials, optimal reduction of wear and tear and use of a Pirelli patent – all different types of transport operator requirements are covered.

Motorcycle Tyres

Pirelli confirms its competitive advantage in terms of performance and safety on the motorcycle tyre market, characteristics that have made our Company the best tyre maker in this segment. However, by anticipating market demand, Pirelli is also focusing its research on the environmental performance of its motorcycle tyres, by equipping the innovative BMW C Evolution electric scooter. Engineers at Metzeler (the 100% Pirelli owned brand) are developing the new Feelgreen project, which will lead to marketing a product that, in comparison with the present standard, will reduce weight by 13% and rolling resistance by about 25%. However, the driving performance of the Feelgreen maintains the characteristic elements for which this brand’s products are famous: fast warm-up and handling, which are essential for city driving conditions. Feelgreen was designed with the support of the FEA (Finite Elements Analysis) technique. It a high silica content compound, new tread design and new profile that were specifically designed to reduce rolling resistance.

For the overall efficiency of motorcycles, the influence of this tyre characteristic is less significant than it is in the fourwheel vehicle world.

CyberTM Tyre

The integration of electronics in tyres is one of the cornerstones of Pirelli’s premium innovation strategy, aimed at guaranteeing continuous monitoring of key physical parameters, particularly tyre pressure. The use of tyres whose pressure is 20% less than its recommended pressure may result in up to 3% higher fuel consumption, with a correspondingly greater environmental impact in terms of CO2 emissions.

National Transportation Safety Board studies have shown that for every 20 kPa of under inflation, there is an average increase in fuel consumption of 1%.

Furthermore, tyre pressure that is 20% below what it should be causes irregular wear on the tyre tread and consequently increases wear and tear by 25%, which translates into a 30% reduction in the lifetime of the tyre. Pirelli is able to offer its customers a family of Cyber products for monitoring tyres:

  • the CyberFleet™ TPMS (Tyre Pressure Monitoring System) for truck use;
  • the Cyber™ Tyre TMS (Tyre Mounted System) for car use.

In particular the CyberFleet™ technology, already available on the Brazilian market for end users (fleets of trucks, buses and dealers) since 2012, uses an electronic sensor embedded in the tyre to dialogue with the fleet management centre, reporting tyre pressure and temperature in real time. The new system is designed to keep tyres under continuous control by measuring any faults to assure proper maintenance. This leads to a significant reduction in the environmental impact from tyre use, by lengthening its useful life and limiting fuel consumption, as well as having a big impact on fleet safety.

The Cyber™ Tyre system of monitoring tyre dynamics, initially applied to car use, can interact in real time with the systems for controlling vehicle dynamics, benefiting driving safety, performance and fuel consumption.

The TMS technology is a high performance solution of the TPMS system that is already widely used on cars in the United States. It can integrate additional functions, such as the amount of vertical static force to optimise tyre pressure according to load, and the RFID, or electronic tag that uniquely identifies the tyre. The Pirelli Cyber™ Tyre system, which is at an advanced stage of development and testing with certain prestige and premium car makers, constitutes the technological breakthrough that can significantly improve the performance limits of road hold and driving safety. This is accomplished on account of the sensor’s capacity to transmit data and information to the vehicle in real time, being updated at every revolution of the tyre, in contrast with the previous methods used until now to make indirect and relatively inaccurate estimates. The Cyber™ Tyre technology was developed entirely at Pirelli, from the electronics, the heart of the system, to the algorithms for extraction of parameters, the basis for creating new vehicle control systems.
