By 2050 Bridgestone plans to work out a totally eco-friendly tire made from natural materials, says Shoshi Arakawa, Head of the Company, on the World Rubber Summit that took place on May 22-24 in Singapore.
Now Bridgestone is doing a research into the methods of natural rubber deriving from guayule and daffodils as well as studies the process of making synthetic rubber from biomass, carbon and other substances. They also try to make use of the new cellulose fibers to replace polyester and nylon, both being created from oil.
The plan fits in Bridgestone strategy of environmental protection that includes the reduction of CO2 emissions. It would be possible provided that you optimize your vehicle’s fuel consumption, which can be achieved by using a low rolling resistant tire. Moreover, eco-friendly technologies affect the choice of materials for the tire as well as its production process.
Bridgestone claims to create butadiene from bio ethanol that to use it for synthetic rubber as well as to work out carbon on the base of intermediate substances from raw biomass, but the details are kept in secret for now. The company promises to inform the community about the steps of the project implementation.
Continental provides its tires for Mercedes B-class original equipment. These are the Continental ContiEcoContact 5 205/55R16 91V, the Continental ContiSportContact 5 SSR 225/45R17 91W and the Continental ContiSportContact 5 SSR 225/40R18 92W XL.
Continental ContiEcoContact 5 is a new high-performance eco tire with Y speed rating. It features low rolling resistance, which helps reduce fuel consumption as well as reduce CO2 emissions. It also ensures effective wet traction, which is coupled with enhanced wear resistance and a low level of noise.
The Continental ContiSportContact 5 was launched last year (2011). It is made of the Black Chili rubber compound that includes two different polymers to provide for safe handling and reliable wet grip. The tire offers smooth and comfortable operation and can also lower your vehicle’s fuel consumption thanks to reduce rolling resistance. The tire equipped other Mercedes cars, namely E-Class, S Class, SL Class, CLS Class, M Class, GL Class and Viano.
Mercedes have chosen the SSR (RunFlat) version of the ContiSportContact 5 tire for its B-class vehicles. Such tires can go on driving in case of complete air pressure loss at a speed of 50 mph. the distance of 50 miles is enough for you to get to the nearest tire fitting centre where you can replace the tire with a new one.
Although Europe is to increase wheel disk diameters according to the new legislation, Continental is sure that demand for compact car tire won’t fall down, but would show standing growth. It becomes possible thanks to the growing popularity of compact small-capacity vehicles in the area.
Continental hopes that European consumers would welcome their innovative Continental ContiPremiumContact 5 summer tire. Market analysts predict that it can interest a number of car owners since 16-inch H- and V-speed rated tires would be popular soon. The demand for such tires is predicted in Germany, Austria and Switzerland while Great Britain it still on the pick of popularity.
Speaking about popular tire sizes in the EU, it should be said that Continental ContiPremiumContact 5 looks very attractive in this way. The most popular are the 205/55R16V, 175/65R14 and 195/65R15H tires.
Still, now it becomes more difficult to introduce new tires to the area as compulsory tire marking starts from November. Neither is it allowed to speak about marks the tire is going to get according to the new system. However, Continental is sure that there will be no tire to get “A” (the highest mark) for wet traction.
Nevertheless, Continental Continental ContiPremiumContact 5 has already been tested by independent research centers like ADAC and ACE as well as automotive journals like Vi Bilagare and Motor. It showed highest results there.
According to the new tire legislation in Europe all the tires ought to be marked and correspond to the markings and declared features in performance. It made Goodyear think and start testing a great number of its tire to show that their tire meet high standards of quality.
The company has already tested 1200 Goodyear-branded tires (70 models) and 1000 tires (50 models) under the Dunlop brand. The modernization of all tires that took place in the Goodyear Innovation Center in Luxemburg lasted almost a year. The company did testing in advance, a month before voluntary marking while it will become obligatory from November, the 1st, 2012.
Xavier Fraipont, Technology Manager of the Goodyear passenger tire department, is assured that the marking will play an important role and will help the customers clearly read and understand their tires. That’s why the company did their best to make their tires correspond to the new rules.
The tires underwent various tests to reveal their braking performance, hydroplaning resistance, cornering stability as well as dry and wet traction and handling. Dunlop tire markings will be also equipped with dedicated QR-codes to aid smart phone owners get all the info about selected tire.
