The Nexen CP321 summer tyre belongs to the high-speed tyre class, characterised by an increased load capacity, which is optimal for use on the wheels of premium vehicles. At the same time, the model can be used for commercial light trucks, demonstrating increased dynamic and high-speed performance. The main characteristics of this tyre model are long service life and high resistance to overloading. Technological tyres Nexen CP321 have a lot of advantages:
High driving and directional stability at any speed, formed by two stiffening ribs with an aggressive structure of tread segments; V-shaped directional tread pattern, which consists of a number of special functional blocks and elements that enhance the vehicle's directional stability and traction, contributing to the tyre's high-speed performance. The ultra-modern drainage system of the treadway of Nexen CP321 car tyres, consisting of symmetrically arranged drainage grooves diverging from the medial sector of the tread to its shoulder zones, guarantees a confident and rapid removal of excess water from under the wheels of the car, which almost completely eliminates the effect of aquaplaning when driving on wet asphalt. Shoulder blocks with increased stiffness guarantee excellent handling in both straight-line driving and cornering. The wide longitudinal channels quickly evacuate water and snow from the contact patch, preventing aquaplaning. The high density of grooves in the tread centre ensures low noise levels, thus increasing driving comfort.
The tyre provides full controllability of the vehicle and guarantees reliability and safety when driving in all climatic/road conditions.
The Tire Labeling Ordinance specifies the information requirements on fuel efficiency, wet grip and external rolling noise from tires. In addition, reference is made to the winter properties of the product.
The EU 1222/2009 regulation that has been in force since November 1st, 2012 has been revised and will be replaced by regulation EU 2020/740 from May 1st, 2021; From this point on, new requirements apply. The rating classes for fuel efficiency, wet grip and exterior noise have been changed and the layout of the EU label has been adjusted. The manufacturer's product data sheets stored in the EU database can be downloaded via a QR code integrated into the label. Information on snow grip and ice grip is also newly included for tires that meet these criteria.
The following tires are exempt from the regulation: - tires that are designed exclusively for installation on vehicles that were first registered before October 1, 1990 - retreaded tires (until a corresponding extension of EU VO 2020/740 has taken place) - professional off - Road tires - Racing tires - Tires with additional devices to improve traction, eg studded tires - T-type emergency tires - Tires with a permissible speed below 80 km/h - Tires for rims with a nominal diameter ≤ 254 mm or ≥ 635 mm
The criteria and evaluation classes at a glance
fuel efficiency
The fuel consumption depends on the rolling resistance of the tyres, the vehicle itself, the driving conditions and the driving style of the driver. The measured rolling resistance (rolling resistance coefficient) of the tire is divided into classes A (highest efficiency) to E (lowest efficiency).
If a vehicle is completely equipped with class A tires, a consumption reduction of up to 7.5%* is possible compared to class E tyres. In the case of commercial vehicles, it can even be higher. (Source: European Commission Impact Assessment * when measured according to the test methods set out in Regulation (EU) 2020/740)
Please note: Fuel consumption depends to a large extent on your own driving style and can be significantly reduced by driving in an environmentally friendly manner. Tire pressure should be checked regularly to improve fuel efficiency.
wet grip
Wet grip is divided into classes A (shortest braking distance) - E (longest braking distance).
If a car is equipped with class A tires, compared to class E tires, a braking distance of up to 18 m can be reduced when braking from 80 km/h (on a road surface with average grip).* *Source: wdk Economic Association of the German Rubber Industry eV
Please note: Traffic safety depends to a large extent on your own driving style. The stopping distances must always be observed. Tire pressure should be checked regularly to improve wet grip.
External rolling noise
The noise emitted by a tire affects the overall volume of the vehicle and affects not only your own driving comfort, but also the noise pollution of the environment. In the EU tire label, the external rolling noise is divided into 3 classes from A (lowest rolling noise) - C (highest rolling noise), measured in decibels (dB) and compared with the European noise emission limit values for external tire rolling noise.
A The pictogram with the classification "A" indicates that the tire's external rolling noise is more than 3 dB below the EU limit value in force until 2016. B The "B" classification means that the tyre's external rolling noise is up to 3 dB below or equal to the EU limit value in force until 2016. C The classification "C" indicates that the specified limit value is exceeded.
