Edouard Michelin, CEO of the French tyre giant, can see opportunities for technical alliances with competitors, a French magazine reports. As an example, he cites the new tyre and wheel system ‘Pax’, which will be presented jointly by Michelin and Pirelli in Geneva.
In Karlsruhe Michelin has introduced an “Agricultural Service Centre” for the three agricultural tyre brands Michelin, Kleber and Taurus. All questions from German customers regarding use and sale of tyres as well as mounted wheel and tyre systems will be answered.
Goodyear has introduced a new, supermodern agricultural tyre specifically for harvesters and tractor units. The new products have been developed with soil protection and high load resistance in mind. Thanks to its 900 mm width, tractor units equipped with the new DT830 remain within the three metre maximum legal width for highway use without the need for a special license. With a maximum pressure of 2.2 bar the new tyre is capable of carrying loads up to 11.8 tons. For use on delicate soil conditions the DT830 is well qualified with a low pressure of 0.8 bar and a wheel load of 7.5tons it creates a footprint of 96 cm by almost 90 cm, offering a contact area of more than 0.8 square metres. In addition the radial belt cords guarantee an even distribution of pressure over the whole contact area. Goodyear offers the DT830 in three sizes; The 900/55 R 32 to be available in Spring 2001, the 900/60 R 32 available in pre-series at present, and the 900/50 R 42 which is already available through Goodyear outlets. Find out more in the November issue of NEUE REIFENZEITUNG.

Hayes Lemmerz sales and earnings in the first quarter 2000 were at the same level as last year. A significant drop in orders for heavy truck wheels and brake components was compensated by a successful expansion of aluminium wheel capacity worldwide.
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.
Sales of tyre and wheel manufacturer Titan (Quincy/Illinois, USA) have dropped last year to US$ 588 million (1998: US$ 660,8 million). Striking and a bad condition of the American agriculture are assumed to be responsible for the figures showing an EBIT of US$ -11.4 million compared to US$ 8.4 million in 1998.
As Sales And Marketing Director at Trelleborg Wheel Systems (TWS) Rotatec GmbH & Co. KG, Oliver Gehlker has been responsible for the German market since 3rd July. According to TWS, Gehlker, who is 33 years old, is very experienced in the tyre business. Before he signed up to his new job, he held different positions in the tyre industry and retail sector.
Michelin and TRW Automotive Electronics have agreed to develop advanced tyre pressure monitoring technology, hand in hand with Michelin’s PA System Technology. The companies displayed their linked technology . The technology is being displayed at the Convergence 2000 International Congress on Transportation Electronics, being held in Detroit. The TRW system will give drivers advance knowledge of underinflation and allow them to remedy the fault before pressure falls to a dangerous level. In the event of a fast puncture the PAX system ensures the tyre stays on the wheel. The TRW system uses a sensor mounted in a high tec valve that sends details by radio signal to the on board control unit. The agreement will see both companies working towards the most effective method of alerting the driver to possible problems.
Meritor Automotive, a subsidiary of the Rockwell group, has announced the expansion of production at its wheel plant in San Luis Potosi (Mexico) to two million units annually. The expansion is necessary because of increased demand in the North American OE market for light truck and pick-up wheels and includes the completion of assembly facilities. A major consumer is Daimler Chrysler (Dodge Ram).
With the sale of assets Titan International (Quincy/Illinois), a manufacturer of speciality tyres and wheels, has exited the oe business with lawn and garden equipment as well as all terrain vehicles (ATVs) and improved its second quarter results due to the price paid by Carlisle Tire and Wheel Co. The new strategy of Titan will be to concentrate on agricultural and construction wheel business and tyre assemblies and to focus more on aftermarket demands.
The tyre can no longer be regarded as an isolated part of a car but is integrated into an increasingly complicated network or system. Progress in electronics especially has been revolutionary and has enormous influence on the work of tyre technicians. The engineers have to think in systems and integrate the tyre into all parts of the motive power of the car. Between the two corners “tyre wheel system” and the engine, is a wide field which the car makers and their suppliers are exploiting step by step. Immediately next to the tyres are modules such as brakes, shock absorbers and axles. Around the tyre is the “chassis”. The producers of certain of these elements in the past developed their own product without contacting the producers of neighbouring chassis parts. They were driven by their customers in the car industry, who gave information about the performance of the product with the target that all the parts should be compatible. As development progresses, this becomes harder and harder. In the future the suppliers will be forced to cooperate one with another, in order to make the best possible technology available for the car.
Hayes Lemmerz, the world’s leading supplier of wheels, has announced record 1999 fourth quarter and full year figures in both earnings and sales. The strong expansion of the wheel business (especially aluminium wheels) and the acquisition of CMI are the main reasons for the good results. Hayes Lemmerz also announced the contract for its sixth wheel/tire assembly facility: for BMW in Munich.
New contracts for chrome-cladded steel wheels from General Motors and DaimlerChrysler have prompted ArvinMeritor to expand its San Luis Potosi (Mexico) facility. Staff numbers will increase from 300 to 450.
The 50m $ sale of 68 percent of the shares in Minardi F1 racing team owned by Gabriele Rumi (Fondmetal alloy wheel producer) seems likely to fail. Minardi – planning to start next season with Michelin tyres – could not find a motor supplier for 2001, so that potential purchaser Panamerican Sports Network (PSN) might withdraw.
