To present its new RainSport 3, tyre manufacturer Uniroyal invited us to an aquarium. A choice justified by the technology incorporated in this tyre, directly inspired from a shark’s skin.

To launch the most extreme tyre in its range, tyre manufacturer Uniroyal invited us to Valencia in Spain, one of the hottest regions in Europe. A paradox from the tyre manufacturer who claims to have invented the rain tyre, but a choice justified during the press conference held in an aquarium, in the midst of sharks. The proximity of these creatures aiming to establish the link between the large predator and the technology featured in this tyre.


An aggressive tread design

The Uniroyal RainSport 3 is designed for wet weather performance. Its asymmetric tread perfectly reflects this tyre’s objective: Efficiently drain large amounts of water and provide good aquaplaning resistance. In addition, wet sipes extend across the structure to form multiple biting edges.

However, the RainSport 3 is not uni-dimensional, and is not limited to wet surfaces. It aims to deliver true dynamic qualities and sporty sensations, as attested by the rigid tread blocks on the shoulder.

Uniroyal, who purports to be the inventor of the rain tyre, marks an important milestone in its history with the RainSport 3, which features a technology to drain water, directly inspired from a shark’s skin. A solution that exists in the swimming world with the famous Speedo swimsuit, no longer authorised in competitions since it gives a significant advantage to swimmers who use it.

The Shark Skin Technology is defined by the intricate tread design in the grooves of the tyre. This technology aims to accelerate water drainage and reduce flow turbulence. It has even been awarded the IF product design award 2014.
