Goodyear launches new UltraGrip 8 winter tyre.

10-02-2011Product group: Car   Category: Tyre launches

Seville, Spain, February 7th, 2011 – Goodyear, one of the world’s leading tyre companies, is proud to introduce the new UltraGrip 8 – the first directional tyre with Goodyear’s patented 3D-BIS (Block Interlocking System) Technology throughout the entire tread pattern. Goodyear’s innovative technology ensures the new UltraGrip 8 answers the most pressing needs of drivers in a winter tyre: more grip and shorter braking distances, as well as improved braking and handling. Performance tests run by German TÜV SÜD Automotive1, one of Europe’s leading testing and certification organisations, prove that the new Goodyear UltraGrip 8 provides 3% better snow and 3% better wet performance, with  4% shorter braking distance on wet roads (on low friction asphalt)1  16% more resistance to aquaplaning on curved wet roads,1  3% shorter braking distance on snow,1  5% more traction grip on snow. “4% shorter braking distance on wet roads versus leading competitors in the market translated into metres means 1.6 metres which is a significant advantage. Being able to stop with your car more than one metre earlier is an enormous safety benefit in an emergency braking situation,” explains Hugues Despres, Goodyear Consumer Brand Director, Europe Middle East and Africa.

UltraGrip 8: standing on the shoulder of giants

The new Goodyear UltraGrip 8 builds on the outstanding performance results of its predecessor, the UltraGrip 7+, which received high praise for its performance from many leading international testing organisations and auto magazines including ADAC, Autobild, Auto Motor und Sport and Auto Express, Britain’s biggest selling car magazine, which declared the tyre “the safest tyre for the coming months” last winter. Goodyear’s UltraGrip winter tyres are one of the most successful winter tyre families ever, with excellent results in dozens of winter tyre tests since the introduction of the first UltraGrip.

Excellent performance in all winter weather conditions

Winter is one of the most challenging times for drivers. Temperatures are low and road conditions can vary greatly, with swift changes from dry to wet and snow or unexpected icy conditions. A winter tyre needs to perform well under all these conditions. The new UltraGrip 8 combines a number of innovative technologies that enable it to deliver top performance under a wide variety of winter conditions.

3D-BIS Technology

The UltraGrip 8 is the first directional tyre using the latest generation of Goodyear’s highly effective 3D-BIS Technology throughout the entire tread pattern. Goodyear’s patented Three-Dimensional Block Interlocking System (3D-BIS) allows an increased number of sipes in the tyre’s tread. The more sipes, the better the grip: A high sipe density gives extra grip on ice and snow because sipes provide edges which literally bite into the snow and ice for strong grip and traction as they open up before coming into road surface contact. To provide excellent handling and braking performance on both wet and dry roads however, the blocks need to be stiff and solid. For this Goodyear engineers have developed the ‘3D Interlocking Effect’ of the sipes. Inside each sipe, the walls have raised pyramids and holes. When the tread blocks come into contact with the road the sipes lock tightly thanks to this special waffle shape. This provides the required block stiffness for excellent handling and steering response on dry and wet roads.

Next generation tread compound

The tread compound of the UltraGrip 8 combines the use of a functionalised polymer and of a traction resin. The former leads to an improved bonding to the silica thereby ensuring an optimised mileage and fuel efficiency while the latter ensures an outstanding grip on wet and dry roads. The maintained rubber elasticity at low temperatures is responsible for the excellent traction and handling on snow & ice.

Higher net contact area.

The new UltraGrip 8 also features a higher net contact area, which leads to an optimised footprint pressure distribution. The bigger contact patch of the tyre offers improved braking performance and more control in icy conditions.

New tread design

Good performance in wet and slushy winter conditions is imperative in a winter tyre. With its full depth directional V-grooves, the UltraGrip 8 cuts through snow, slush and water to deliver improved water and slush evacuation. The double V-groove design – one V-groove for evacuating water and one for gripping snow – ensures that the tyre provides top grip in various winter conditions. The improved side gripping grooves, with their high number of biting edges, give the tyre better side grip on both snow and wet

With its light weight carcass structure and low rolling resistance carcass compounds, the UltraGrip 8 delivers optimised fuel economy and CO2 emission levels. “Excellent performance on safety parametres such as handling and braking are key requirements in the development of all Goodyear’s products. As with all our tyres, we subjected the UltraGrip 8 to extensive and stringent performance tests,” says Despres. “We are proud to introduce a new winter tyre that builds further on the long history of the UltraGrip family’s successful track record. Winter is a challenging time for all road users and it’s absolutely important that cars are equipped with highly effective winter tyres that ensure top levels of performance at cold temperatures and in all kinds of winter weather conditions,” says Despres.
