The RainExpert in detail

The expert for short stopping distances on wet and dry roads.
No matter if it's raining or dry, the RainExpert helps you to stop quickly and safely. This is achieved by means of specially angled sipes in the tyre shoulders and at the centre of the tyre which provide for more grip when braking. The result: short stopping distances on wet and dry roads with the Uniroyal RainExpert.

The anti-aquaplaning expert.
The RainExpert offers a high degree of protection against aquaplaning. The double concave grooves with greater volume in the centre of the tread pattern stop the water from swirling and disperse water more efficiently. The result: greater protection against aquaplaning with the Uniroyal RainExpert.

The long-life expert.
To ensure optimum performance and a long life the RainExpert features visual alignment indicators (VAIs) on both sides of the tread to indicate uneven wear. The VAIs help to indicate incorrect wheel alignment (toe and camber settings) at an early stage so that corrections can be made to avoid excessive tyre wear.

Uniroyal's RainExpert Delivers Improved Safety & Wear

Traduction => http://translate.google.fr/transla [...] r&ie=UTF-8

Over the years, Uniroyal has developed a strength in the area of wet weather tyres, so it is hardly then surprising that its latest product has been named the RainExpert.

The new range for super-mini, compact and medium cars covers 78 sizes between 13 and 16-inches – some 96.5 per cent of the European compact and high performance segment. The first 43 sizes were released in January, and a May launch is planned for the remaining 35 sizes.

Uniroyal reports improved performance compared with its 'Rallye' tyre: up to five per cent more resistance to aquaplaning, as much as a three per cent reduction in braking distances, and five per cent more mileage performance. The tread on the RainExpert, comments tyre engineer Jürgen Brockmann, has a hydrodynamic tread featuring a directionally orientated and consistent V-shaped pattern. A three or four groove version is used depending on the tyre's size. In wet weather, the tread pattern's circumferential grooves are designed to quickly take up the water and efficiently disperse it to the sides of the tyre via channels between the tread segments.

"Even the grooves themselves have a double concave shape", explains Brockmann. "This prevents any swirling of water which would counteract the effect of rapid water dispersion." Depending on the tyre's width and speed, and the depth of water on the road, a rain tyre needs to shift up to 42 litres of water per second to maintain contact: "This is where the V-shaped tread pattern helps because it is better than a non-directional pattern at expelling the water in the right direction away from the contact patch", he adds.

Wet braking performance of the new RainExpert is improved over that of its predecessor, reports Uniroyal, through the use of using 'special' sipes instead of standard sipes. These sipes increase tread stiffness during braking, leading to shorter wet-braking distances. Extra safety also comes from the tyre's more stable tread elements in the shoulder region. They serve to improve handling and assist the driver in critical steering manoeuvres.

As previously mentioned, the RainExpert's mileage has been improved over its predecessor. "Abrasive tyre wear is low and evenly distributed thanks to the RainExpert's well-balanced tread stiffness", explains Brockmann. "This adds up to a long tyre life and, consequently, more economical and resource-conserving driving."

Three millimetres – this is the summer tyre wear limit frequently recommended by tyre safety organisations, the limit at which water drainage rapidly deteriorates, the risk of aquaplaning increases significantly, and braking distances become longer, above all on wet roads. "So we decided to give the new RainExpert a system of tread wear indicators to warn drivers once that limit has been reached", explains Lukas Kosmala, product manager at Uniroyal. "Small bars with a height of three millimetres have been placed between the individual tread elements. The tyre's wear limit has been reached once the bars are at an even level with the surrounding tread." A raindrop on the tyre shoulder indicates where these S-TWIs (summer tread wear indicators) are located. The bars run across the grooves in a line with the raindrop.

Another feature in extending the life of the tyre is the VAI or visual alignment indicator on the tread. VAIs are umbrella symbols vulcanised into the tyre and serving as visual identification of a vehicle's misalignment. "Wheel alignment is precise if the VAIs are worn down evenly on both sides of the tread. If the indicators are worn down to different degrees, wheel alignment should be checked to prevent uneven tyre wear", advises Kosmala.

Bsr. Alors qui aurait des info ou des test a faire partager???

Up ! Des retours ?

intelligent le coup des parapluies sur le pneu! mais pas forcément révélateur d'un défaut de géométrie:
 
tous les pneus avants droits sont un peu plus usés sur le bord extérieur à cause des nombreux ronds point

Slt. le systeme de marque en profondeur existe sur bien d'autres pneus comme les nokians entre autres. il est marqué des chiffres de 0 a 9 si je me souviens bien, sur la bande de roulement au centre. ils sont graduellement de plus en plus profond pour ainsi determiner tres precisement l'usure du pneumatique. voila pour l'info, a+.

Assé grocier comme dessin, ça doit faire du bruit ça non

Slt. ce sont des structures en 3D comme les hankook k110 v12 evo. ces derniers ne sont apparament pas plus bruyant qu'un autre pneu aux dires des derniers testeurs (des k110) donc il n'y a pas de raison que cela soit different pour le rainexpert.......................mais evidament comme chaque pneu est different...!!!

me réjoui d'avoir des retours ou des test sur ce pneu....

J'ai acheté 4 Uniroyal Rain Expert il y a 2 semaines en gros, c'est sympa comme pneus, surtout quand il pleut. Au début j'hésitait sur la marque, mais chez oponeo.fr on m'a coinvaincu  
Seulement, j'ai pas de cette ceinture au milieu, vous pensez que c'est à cause de la taille (185/60/14)?

Oui, ça dépend de la largeur du pneu ... Elle apparaîtrait dès 195 ...
... à confirmer ...

moi c'est bon, je viens d'en acheter 2 pour mon berlingo en 175x70x14...montage demain.45€ chez autobacs en promo.

c'est bon c'est monté, plus qu'a attendre qu'il pleuve pour tester....

oui, tiens nous au courant

et quoi les gars, toujours pas d'autres avis sur ces pneus

puis ben moi peut pas test, il pleut pas....

Y'a des test sur ces pneus la? Merci

je viens d'en commander 2 pour ma stilo 205/55 R16 V
 
on verra ce que ça donne...

  La meme taille que moi en plus. J'attend avec impatience ton avis  

j'ai rdv le 8, la saison des pluies va commencer

A titre de renseignement, ça coute combien un uni comme ça?

j'en ai pour 180€ posé... chez siligom
