New Year in Russia Michelin met on the Eastern calendar. New items of the winter season were at the end of January. On the ground in Dmitrov visited and dealers, journalists and employees of OOO Michelin. Russian company for the production of tires. " What the French know how to make winter tires, it is known to all. The evidence of this - many victories in independent tests. But the active participation of the most prestigious automotive events subconsciously brings to mind that tires Michelin (at least in Russia) - the inheritance of the elect. In fact, the French manufacturer of fully democratic, and new this season - a clear confirmation of this. Michelin Alpin 3 - frictional directional tire for passenger cars of small and middle classes. Intended primarily for the European market, so in addition to purely winter as developers have paid attention to tire safety on wet and snow-covered road porridge, which makes an interesting new product for use in our major cities, buried chemicals. The bonus, which is important for owners of relatively inexpensive machines - increased durability and fuel economy. As the developers say, in comparison with "average competitor» Alpin 3 "walks" on 13 thousand kilometers long (ie, almost another winter) and during operation saves up to 96 liters of gasoline, which is comparable to the price of tires. But more impressive is another figure. When braking from 60 mph on a wet road at the time of stopping the machine, "booted" in the Michelin Alpin 3, the same car, but tires and competitors will have an instantaneous speed of 21 km / h, which still have to repay. This is achieved through the use of a new rubber compound with the addition of sunflower oil (!) Oil. Which, incidentally, also reduces the environmental load of rubber dust. The tread pattern of Michelin Alpin 3 does not cause much surprise: a pronounced symmetrical, directional, V-shaped, with numerous lamellae. Past and are the main "secret" of the tire. Firstly, the lamellae in comparison with "average competitor", almost half (47%) more. Secondly, they have a complex, mathematically well thought-dimensional form. Meaning Michelin BDS technology that Sipe ("knife grooves"), separating lamellae are wavy form in two planes. Z-shaped sipes easily bent in its upper part, crashing edges into the snow and ice. A primary (inner) array of lamellae remains monolithic through mutual engagement "teeth". Lamella does not "walk" here - improved acceleration and braking dynamics and exchange rate stability. Form of lamellae with the deepening of change (VG - variable geometry - variable geometry technology) to sustain a high operational performance throughout the life cycle. Upon reaching a residual tread depth of 4 mm (which is easily determined by the wear indicators) the number of lamellae is 75% larger than its nearest competitor on the tires. In 2006, Michelin Alpin 3 will be released in 16 different sizes - from 165/70R13 79T to 205/55R16 91T. Michelin Latitude X-Ice North - dream extreme. This shipovannaya directed tire for SUVs. Emphasis on the behavior of tires on icy, snow-covered road and off road. After all, it is intended primarily for North America, Scandinavia, Russia and northern China. Besides the already mentioned technologies BDS (or BAS - Bi-Active Sipes) and VG important (even essential) technical solution is a new tire spikes. They are steel, dvuhflantsevye, with the emission of 1,2 mm. The attentive reader of our magazine will remember that these are the spikes recommended last fall, a leading domestic oshipovschik - company Tecom. Aluminum studs are also used, but in countries with less "chemicalization" roads. The height of the protrusion (departure) spike - a compromise solution. To do less - degrade braking dynamics (every tenth of a millimeter increases the braking distance by 3%). More - increase the risk of tearing spines out of the nest and the stitching of the core of the asphalt. Large enough departures spike required to develop a new method of fastening. But winter is not just ice. On the winter road is and loose snow, porridge, and just water. Overcome this adversity helps enough "discharged" tread ("negative" - ??39%). The system of grooves helps remove moisture from the contact patch and liquid mud. A large "block" facilitates the movement of virgin snow. If you also have to get out of a deep rut, then it will take slats in the shoulder area. They work in the slush, and snow. Yet mastered five sizes - from up to 215/70R16 100Q 255/55R18 109TXL. Another six will appear in a year. Vladimir Zaborschikov Photo Michelin
