Best in class aquaplaning resistance. Shark Skin technology shrugs off water. The RainSport 5 continues all of these traditions, as well as offering all of the enhancements in technology you’d expect from a performance tyre. As Uniroyal are owned by Continental, they share many of the technologies that go into Continental tyres, but with Uniroyal’s singular focus on wet performance. As well as an asymmetric tread pattern designed to quickly clear water from the tread of the tyre, they also use Uniroyal’s own “Shark Skin Technology”. Inspired by the way shark skin is actually made of tiny interlocking scales, the surface of the tyre receives a similar treatment. Just like the skin of a shark, this ensures that water flows smoothly and uniformly off the surface of the tyre into draining sipes leaving clear tread to make contact with the road. Uniroyal has even done something clever with the drainage sipes in the tread blocks, using something called Aqua-Twist technology to quickly shed water off the tread of the tyre. These features combined with the new compound give this tyre the class-leading resistance to aquaplaning you expect from a Uniroyal RainSport. Uniroyal set out to make this better than the RainSport 3 and they have definitely achieved that. Uniroyal has also put a real emphasis on tyre life, fuel economy, and low noise with this new design. The new compound, pattern, and stiffer shoulders help ensure even tread wear and longer tyre life – Uniroyal is quoting up to 15% improvement over the RainSport 3. Fuel economy and rolling noise are also improved. Ride quality is slightly improved over the 3, offering a positive and sporty, yet comfortable connection with the road. If you want a tyre that performs outstandingly well in the rain, offers all the benefits of a modern compound and tread pattern, and lasts a long time, you cannot go wrong with the Uniroyal RainSport 5. 10.07.2024, 08:47:33.
