The rain expert for compact cars. Perfect protection for the wet!
The RainExpert is the perfect choice for compact cars. For greater safety in the rain with high economy—the best recommendation for everyone who drives a compact class car. A specialist for even greater safety on both dry and wet roads. Uniroyal offers more than 45 years of rain tyre know-how for optimum performance in the wet. High aquaplaning protection. Fits perfectly for example to Ford Fiesta, Renault Twingo and Alfa Romeo Mito.
Technical details:
The expert for short stopping distances on wet and dry roads
The long-life expert
The anti-aquaplaning expert
High aquaplaning protection. Double-concave-shaped grooves and increased groove volume in the tread centre avoids water turbulence in the grooves and substantially improve water dispersion for high aquaplaning protection.
Long service life. Optimised stiffness distribution across the tread provides evenly low tread wear for a long service life. There is also a higher stiffness of the shoulder blocks providing a high degree of safety during critical steering manoeuvres.
Short braking distances on wet and dry roads. Directionally-inclined sipes in the tyre shoulders and tread centre improve the support for the lug halves during braking, leading to increased longitudinal tread stiffness. The braking distances on dry and wet roads become shorter.
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.

02.10.2015fromPeter Kershaw Drove this tyre in the hardest rain I've ever driven in on Friday 3rd July 2015 North of London those who experienced this storm will probably remember.
Water was level with top of curb stones at times it was falling so heavily. It was very evident I still had control while those around me did not at times
03.05.2015fromPia Good tyre for wet road conditions in city traffic. Slightly noisy but safety outweighs.
01.02.2015fromC. Hill Excellent tyres having specified them before-original spec on many cars of the era
12.11.2014fromJohn Superb tyres these uniroyal rain tyres. Now have all our family cars on them, so no better recommendation for safety & grip. Yes, the sidewalls are a bit softer than other brands but the superb grip in all conditions outweighs this and once you get used to the feel of the slight flexing when changing direction sharply they are very predictable. Our family now have rain sports on all our cars, a mixture of RS2, RS3 & rain expert. All are superb and are great for the lower grip levels and lower temperatures encountered in Scotland.
