Bridgestone Enliten lightweight tyre tech to reduce rolling resistance, weight
Bridgestone has launched Enliten, a new lightweight tyre technology designed to reduce rolling resistance and contribute to the reduction of a vehicle’s CO2 emissions, while providing the same wear life as a standard original equipment tyre. The company states the new material will benefit car manufacturers, drivers, and the environment.
Nokian shares progress with rolling resistance reduction
Nokian Tyres says the rolling resistance of its tyres is now eight per cent lower on average than in 2013. It points out that this reduction is the equivalent of exhaust fumes from 65,000 cars.
What Car? True MPG: fuel economy closer to reality, but still 4.9% worse than claimed
What Car?’s True MPG testing has revealed that new official fuel economy tests introduced late last year are providing more accurate results than ever before – with some cars even beating the official figures in the real world.
Fuel savings a focus for Kumho Ecowing ES31
A new Kumho tyre designed with low rolling resistance and fuel savings in mind has been released in the UK. The Kumho Ecowing ES31 is available in 38 sizes, and Kumho Tyre UK says almost 70 per cent of these sizes carry an EU tyre label rating of ‘B’ for fuel efficiency - this is, it adds, – an “impressively high margin by any standard.”
Love thy neighbour: Proximity to US tyre makers decisive in Evonik’s choice of plant site
Plans to build a precipitated silica production facility in the US state of South Carolina have been officially confirmed by Evonik Industries. The new plant will be located in the Bushy Park industrial area near Charleston, close to the factories of a number of tyre makers, including Michelin, Bridgestone, Continental, Trelleborg and (as of 2017) Giti Tire. Evonik Industries will invest approximately US$120 million in the plant, which will be completed in 2018.
Bridgestone researchers claim to have reduced tyre wear by 60%
Bridgestone recently gave a presentation to the Japanese Cabinet Office on the subject of its "ImPACT" resource saving, strength increasing tyre polymer research project conduction in association with Tokyo University. The project, which seeks to bring government, industry and academia together are to: developing high-strength materials, making each component thinner and lighter; and to improve fuel economy and save resources through weight saving and increased durability as well as reduced fuel consumption. Initial results suggest the scientists “succeeded in the development of materials that [offer]…a 60 per cent reduction in wear rate.”
Iveco chooses Michelin OE tyres for Stralis XP truck
The New Iveco Stralis XP heavy truck will fit the next generation of Michelin X LINE Energy tyres as original equipment. The new X LINE Energy range is the first tyre range to receive an A grade rolling resistance ratings in the drive, steer and trailer positions, according to the European Tyre Label measure. As a result, Iveco customers can opt for the market’s first heavy truck tyre range to earn an “A” rating for rolling resistance on every axle.
Orion’s new carbon blacks “improve fuel efficiency of tyres”
On 23 May, US-based Orion Engineered Carbons released three new products that it says create more fuel efficient tyres. The new tyres come in response to consumer demand and legal standards for vehicle fuel economy. As far as the US federal version of these rules are concerned, these grades offer reduction in rolling resistance via narrow particle size distributions and lower sidewall hysteresis; and lower air permeation through the inner liner for better tyre inflation consistency.
Goodyear highlights effects of truck tyre choice on CO2 emissions
Goodyear has added its voice to the debate on the integrated efforts to reduce carbon dioxide (CO2) emissions in the transport industry. The tyre manufacturer points out the effect that recent truck tyre developments have had on significantly reducing CO2 emissions made by commercial vehicles. It also highlights the effectiveness of the EU tyre label in achieving CO2 reduction across the transport industry.
Solvay Silica appoints Lintech as a US distributor
Lintech International LLC has reported that it has been appointed as a non-exclusive distributor for Solvay Silica in the US, covering markets including the manufactured rubber goods (MRG) market.
TÜV SÜD certification for ZC Rubber’s rolling resistance test equipment
With the MSTYR15 project now examining the correlation between claimed and actual EU tyre label performance, it is more important than ever for manufacturers to utilise test equipment they can trust to deliver reliable results. Hangzhou Zhongce Rubber Co., Ltd (ZC Rubber) reports that the machinery it uses to test rolling resistance was recently inspected by TÜV SÜD, and was certified as highly accurate.
How excessive tyre pressure can deflate share price
A simple “trick” – or perhaps we should say “cheating” or “fraud” – has been common practice in the European automotive industry, to the displeasure of environmental organisations: Place a car with excessive tyre pressure on a dynamometer and – voilà – lower fuel consumption levels and emissions are recorded thanks to the ‘optimised’ rolling resistance. Mitsubishi has conceded carrying out this practice in Japan with test data submitted to the Ministry of Land, Infrastructure, Transport and Tourism. This time round it doesn’t affect, as in the case of Volkswagen and its ‘cheat’ software, millions of vehicles, rather ‘only’ 625,000 small cars, the majority of these off-take production for Nissan.
Hankook enlarges Ventus S1 evo² range with low rolling resistance sizes, announces Mercedes-Benz fitment
It appears that Hankook Tire has introduced a low rolling resistance version of its flagship Ventus S1 evo² tyre. A statement released following the company’s Frankfurt motor show press conference refers to the addition of “very low rolling resistance versions in several sizes” and states that two of these dimensions have been selected as original equipment tyres for the Mercedes-Benz C350e plug-in hybrid.
Michelin solutions launches ‘Effitires with fuel commitment’
Michelin solutions used the Commercial Vehicle Show 2015 to launch what it calls “a new pan-European value-creation offer for road transport fleets”. In other words, this means the firm is offering price per kilometre (PPK) tyre management contracts with a contractual fuel saving commitment, for the first time. Michelin solutions calls this – ‘Effitires with fuel commitment’ and it is designed to make both hauliers’ and own-account operators’ fleets more efficient by combining outsourced tyre procurement and expert tyre management with a commitment to saving fuel.
Nokian announces ‘A’-rated winter tyre for electric vehicles
Nokian Tyres is claiming an industry first with the release of a Nokian Hakkapeliitta R2 fitment designed for the electric BMW i3. The Finnish manufacturer says the winter tyre has achieved an ‘A’ European tyre label rating for rolling resistance – a boast that not even the most optimistic tyre maker has voiced since the label’s introduction in late 2012. But given Nokian’s impeccable credentials as a winter tyre specialist, we can be confident that this particular Hakkapeliitta R2 does exactly what it says on the tin. To quote the manufacturer, the tyre “allows for safe, economical, and high-performance driving on snow and ice in demanding Nordic winter weather.”
