Defect Investigation For Ameri*550

The US National Highway Traffic Safety Administration has announced that it is to open a defect investigation into the General Ameri*550 AS P235/70R16. The tyre is manufactured by Continental Tire North America and has been used as a replacement tyre for Firestone Wilderness ATs on Ford Explorers. The investigation follows initial research results show tread separation claims running at 124 per million. This exceeds the rates for any of the other tyres on the NHTSA list of tyres to be examined. The claims against the General Ameri*550 include seven crashes in which the tyre separation allegedly led to injuries. The NHTSA states that the defect investigation does not mean that it has determined these tyres to be unsafe, or to have a safety related defect. Simply that it warrants further investigation.

TARRC Seminar

The Tun Abdul Razak Research Centre (TARRC) has been deeply involved for the past two years in an EU-funded CRAFT project, the aim of which is to achieve better assessment of new tyre casing integrity in order to increase the number of tyres retreaded in Europe. TARRC hosted a seminar to discuss the impact of existing and proposed regulations on retreaders and some findings from the CRAFT project. The reason for the CRAFT project was based on a concern by retreaders that the quality of some new tyre casings was decreasing, with the danger that the industry could be deprived of its basic raw material. Principal research objectives included the development of new tests in order to predict the retreadability of new tyres, the establishment of a best practice drum test and a league table of tyre brands, rated according to their retreadability. The project will be finished this year. In investigating retreadability, TARRC tested a number of tyres in accordance with Regulation 54, the standard against which new tyres are tested. Under this standard, tyres are drum tested for 47 hours. The results were extremely surprising and indicate that either Regulation 54 is deeply flawed, or that the tyre industry has a problem. Testing 295/80 R22.5 M-rated tyres, the results showed a failure rate among new tyres of 20.8%. The new tyre manufacturers usually carry out their own tests and their failure rates are nothing like this figure, which begs the question why is there such a disparity between manufacturers’ results and the findings from TARRC? Under the new retreading Regulation 109, tyres are chosen and tested at random by an outside agency. Is there any independent validation of the in-house testing of new tyres? A proposal was made that new tyre manufacturers and retreaders cooperate in a programme of cross-testing new tyres in order to try and solve this apparent anomaly. Whether or not this will happen remains to be seen.

New Tyre From Debica: Passio

Their latest product, the summer tyre Passio with a T-speed rating was presented to the European press and public at the end of January. This tyre is intended to succeed the Debica Vivo. For Zdzislaw Chabowski there is no doubt that in future his factory in Debica will be very important within Goodyear’s integrated production system all over the world. This article presents the new product, the company and the management. The product is a summer tyre, a so called bread and butter tyre, with speed index T, being developed in Goodyear’s research and development centre (GTCL) in Luxemburg. Afterwards it will be comprehensively tested on gravel roads, motorways and also on the race track in Vallelunga, Italy. According to the manufacturer, comfort and driving conditions on both wet and dry roads have been improved. Noise levels have been reduced, and compared to its predecessor, Passio should be able to reduce the braking distance on both dry and wet surfaces. Passio is a tyre for both the original equipment and the replacement market which soon will be available in nearly every European country. Debica Tyres was founded in 1939 and transformed into a public limited company in 1991, whose shares have been traded at the Warsaw stock exchange. The Polish government found a strategic investor in Goodyear at the end of 1995, who, in two steps, has increased its financial interest in the company and has become the majority shareholder meanwhile.

“Eufori@” – Two Premieres For Pirelli

Consumer demand for run-flat tyres is at an all-time high. In the U.S., for example, a recent study found that nearly seven out of eight consumers place run-flat tyres at the top of their list of features desired on new automobiles. Therefore it is expected that the demand for run-flats will increase within the next few years. This is one of the reasons why Pirelli has developed such a tyre on its own, regardless of the fact that the company is working together with Goodyear and Sumitomo on Michelin’s PAX system. But the launch of the new tyre – called “Eufori@” – was not the only premiere for Pirelli: this run-flat is also the first tyre manufactured using the Italians’ MIRS technology. In size 205/45 R17, the “Eufori@” is original equipment on the new Mini Cooper S, shown at the Tokyo Motorshow at the same time. The name of the tyre, which will of course also be available for the replacement market and in the additional size 225/45 R17, was chosen from more than 20,000 suggestions made during an internet campaign at the end of last year. “We expect that in three years run-flats will account for about 10 % of the high performance tyre market”, explains Francesco Gori, Senior Vice President Market Development Unit at Pirelli. “Other car manufacturers who are interested to use Eufori@ as original equipment are BMW, DaimlerChrysler, Ford and VW/Audi”, adds Maurizio Boiocchi, responsible for research and development at Pirelli Reifenwerke. From remarks such as these, one gets the impression that run-flats will become standard equipment on cars much faster than did other features, such as ABS.

Internet Usage Inefficient

According to research from Deloitte & Touche, businesses are not making the best use of Internet trading facilities. Most, they say, concentrate only on the supply chain element of their e-trading. According to the Deloitte & Touche report a full integration of the demand chain and supply chain, from basic supplier to consumer, offers greater shareholder value, increasing profitability by up to 70 percent.

A Question Of Grip: The Conti Winter-Roadshow 2001

Time has come for German car drivers to renew their acquaintance with the cold season. Using their annual country-wide winter roadshows, Continental’s experts are explaining the aim and object of winter tyres with their better grip on low temperature roads. Because of a special compound – in contrast to summer tyres –they are made as flexible as possible for road temperatures below seven degrees, in order to produce enough grip when starting, braking or cornering. This flexibility ensures the necessary traction of the tread on asphalt, snow and ice. There are more and more car drivers who realise that adapting to winter tyres has more advantages than merely better grip; a view which is supported by constantly rising sales figures over recent years. Whereas in 1997 30 million of these winter specialists were sold all over Europe, demand rose to 37 million last year. In some European countries even more winter than summer tyres have been sold so far. Thus, last year’s winter tyre market share was about 40% in Germany, 59% in Austria, 57% in Switzerland and 61% in Sweden. About 16 million winter tyres were sold in Germany alone last year. The reason for this demand is the increasing number of new cars with their more powerful engine performance. The trend towards higher performance cars causes the consumer to order winter tyres designed for speeds over 190 km/h. Another reason: car drivers want fun when driving even in the winter, as long as road and weather conditions are appropriate. If possible, they choose tyres of the same size and speed rating as their summer tyres. Also, research by Continental reveals that fun-driving in winter need not be more expensive. Winter tyres will cost about 0,20 Euro each day in use.

Today “Only” A Tyre, Tomorrow A Measurement Tool?

The automotive business is moving more and more towards an “intelligent” chassis control or a “total chassis management”. In this scenario tyres are playing a role of growing importance. Today consumers and tyre manufacturers still focus on comfort, rolling resistance, handling etc. But what about tomorrow? Electronic sensors within the tyre will be able to supply additional information to the driver or to systems like ESP. For 20 years, the interaction between road and tyres has been studied at the University of Darmstadt and has for example led to the so-called “Darmstädter Tyre Sensor” or a special trailer for measurements concerning tyre noise emission. But in mid October – after events in 1996 and 1998 – this was also the place where the third “Reifenkolloquium” was held for international experts to discuss topics related to research and development in the tyre, wheel and related businesses. About 90 attendees were at the event this year. After an introductory speech entitled “The Tyre – Key Component For Driving Dynamics And Steering” another twelve lecturers followed. Divided into four sections “Tyre/Road Noise”, “Tyre Evaluation/Test”, “Models & Simulation” and “Sensors & Road Parameter Evaluation” they reported the recent results of their studies. Some of these, which are not too technical, are summarised in the November issue of NEUE REIFENZEITUNG.
