Uniroyal RainExpert 3: The Ultimate Rain Tire for Compact Cars
Exceptional Performance in Wet Conditions
The Uniroyal RainExpert 3 is designed specifically for compact vehicles, offering unparalleled safety on both dry and wet roads. With over 45 years of expertise in wet performance, Uniroyal has crafted a tire that excels in preventing aquaplaning. This tire is an ideal fit for cars like the Chevrolet Spark, Hyundai i20, and Mercedes-Benz A-Class, providing comfort and safety across its entire width.
Advanced Aquaplaning Protection
Featuring the innovative Shark Skin Technology, the RainExpert 3 incorporates a unique pattern in its longitudinal grooves, minimizing water turbulence and allowing for rapid water evacuation. This technology ensures maximum aquaplaning protection, enabling you to drive confidently through puddles without losing traction.
Short Braking Distances
On both dry and wet surfaces, the RainExpert 3 offers short braking distances. Grip edges enhance the tire's contact with the road, while the Rain Tyre Compound ensures the effective transmission of high braking forces. This combination results in superior braking performance, keeping you safe in various driving conditions.
Reduced Rolling Resistance
The tire's design minimizes block tilting movements, optimizing the contact patch and utilizing stable polymer chains to reduce friction losses. This leads to lower rolling resistance, enhancing fuel efficiency and providing a smoother ride on any road surface.
Experience the Power of Bionics
Inspired by the intricate grooves and ridges of shark skin, the Shark Skin Technology in the RainExpert 3 represents applied bionics in tire design. This revolutionary technology allows water to flow through the tread grooves with minimal turbulence, ensuring rapid displacement. As a result, you can traverse waterlogged roads at high speeds without losing contact with the road surface, significantly reducing the risk of aquaplaning.
Comfort and safety across the entire range Developed for compact- and middle-class vehicles and SUVs. Outstanding aquaplaning safety and ideal comfort. Fits perfectly for example to Ford Fiesta, Renault Twingo and Alfa Romeo Mito.
High aquaplaning safety The new RainExpert 3 has a tread structure based on the shark skin. This special tread minimises water turbulence and channels water away from the tread more quickly. This means the tyre provides a high level of protection against aquaplaning.
Short braking distances on wet and dry roads The tyre tread grips the road surface perfectly, establishing strong contact. This extra adhesion leads to short stopping distances on dry and wet roads.
Low rolling resistance on any road With the RainExpert 3 the tread surface is used to optimum effect in contact with the road. This leads to reduced loss of friction, resulting in lower rolling resistance on all road surfaces and reduced wear.
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.
