Kenda Launches New Snow Tyre

Kenda Tires has completed the long-term test of its latest snow tyre. According to the company, the Polar Trax KR19 is designed to supply the grip and traction on the ice, snow, and wet road conditions. The new product will now be launched into the European market.
Kenda reports that it has produced its latest offering with winter road conditions in mind. The Polar Trax features what the company called a “premium twine construction” and drainage grooves for more efficient water clearance. Handling ability is said to have been enhanced by a special silica compound, which Kenda claims is an essential element when it comes to preventing aquaplaning. The tyre’s zigzag sipes also provide traction and grip to cope with the winter roads.

GE Expands to Meet Demand for Silica Tyres

GE has expanded its capacity for high technology silanes used in the production of silica tyres. Additional capacity was brought on line last week to meet the high demand for GE’s new proprietary process.

“Demand has been very strong for our new NXT silane that helps enable fast and easy dispersion of silica during rubber compounding for silica tyres,” said Dr. Ian Moore, general manager for GE’s global silanes business. “We are focusing resources on new products and processes, and this is another move in our long-term strategy for growth in the silica tyre segment. In fewer than 24 months of design and construction, we developed and deployed an innovative process that delivers vastly increased capacity for silanes.”

Compound Interest

Tread rubber and compounds are continually changing, in order to meet changing needs. The motorcyclist wants superb grip, the truck haulier wants long mileage and the ordinary motorist wants both. Developments such as silica compounds and precure treads that are axle-specific help to achieve these objectives. What’s next on the horizon – using reclaimed rubber perhaps?

Vredestein Ultrac

Vredestein and Giugiaro have teamed up for a second time to produce a stylish ultra high performance car tyre – the Ultrac. This follows the success of the Giugiaro designed Sportrac, which encouraged Vredestein to ask the Italian design studio to work with them on their first venture into the UHP segment.The result is a variation on a theme, the now familiar extended deep vee tread pattern has been touched by natural influences and now follows a sweeping pattern taken from nature, using the veining of a leaf as inspiration. Many will wonder whether a tread pattern designed by a stylist is as effective as a tread pattern designed by a tyre technician, but by adopting the rule that form follows function, the result is a tyre which appears to perform as well as any of its UHP competitors.The real innovation though is in the compound and the building of the tyres. The Silica Silane compound turned the mixing process into a chemical reaction which had to be time and temperature controlled. Further, the tyre building required an accuracy offered only by new tyre building lines. Vredestein invested some 50 million Euro in production facilities for the Ultrac. It is a venture which leads the Dutch manufacturer into the burgeoning UHP sector, however, MD Rob Oudshoorn told NRZ, “We don’t consider this as a growth market, we see it as another opportunity to sell tyres.”

The two latest offerings from Uniroyal are classed as “wet weather tyres”. The RainSport 1 is a high speed (V and W rated) tyre which succeeds the RTT 2 and features include a directional tread with a double-V tread pattern and a silica compound for improved wet grip and lower rolling resistance. The rallye 680 is a T-rated tyre, aimed at the family driver, and it is a replacement for the rallye 580. Again, the compound is silica-based and Uniroyal claims improved performance in the areas of aquaplaning resistance, wet braking, tyre life and noise generation.

Semperit Sport Grip With New Sipe-Technology

Continental’s subsidiary Semperit introduced its new winter-tyre “Sport Grip” for stronger motorised passenger cars to the press at the end of September in Austria. With its new sipe-technology called “Add Traction” and a corresponding profile structure, the new tyre has been designed to meet the most difficult driving conditions of the winter season. In addition, modern silica tread technology will guarantee a balanced handling up to speeds of 210 kilometres per hour. The “Add Traction” sipe consists of three parallel ordered straight sipe pieces which are angled in a “z” shape. In the immobile middle of the block they double the effective length of the grip edges, thus significantly increasing traction. The directional profile of the Sport Grip is also characterised by diagonal profile blocks and enlarged grip edges that optimise traction and side stability. Initially, the Sport Grip is available in 21 sizes from 185/65 R15 Q up to 225/50 R16 H, which represents a market coverage of about 83 percent.

ContiPremiumContact – Developed to Customers’ Specifications

From the spring of 2000 the new ContiPremiumContact will gradually replace the ContiEcoContact CP as the tyre for top-class cars. With this new summer tyre Hanover expects a significant increase in the replacement and the original equipment business in tyres with speed categories of 190 km/h and above during the next few years. The new tyre was presented to the international trade press in mid-February. A study undertaken by the development/consultancy “Institut für Sensorikforschung und Innovationsberatung” has established that the first and foremost user requirement of a tyre is safety. By which he means aquaplaning protection, short brake distances, steering precision, roadholding and tracking stability. With three construction specifications – an innovative bionic contour emulating a cat’s paw that extends in width when the brakes are applied, an asymmetric tread pattern and a third-generation silica compound – the PremiumContact wants to fulfil these requirements. Continental is seeking a total of 37 original equipment approvals from 14 vehicle manufacturers with the PremiumContact – available in eleven different 16 and 17 inch sizes. In the replacement business the ContiPremiumContact will initially be launched in 13 sizes, a 75 p.c. market coverage, according to the manufacturer. The new tyre will be positioned at the same price level as its predecessor.
