Winter tires 2011

On the threshold of a winter season 2011 Tires the companies have exhausted some novelties. Basically it is frictional (Without thorns) models of winter tires. New models with thorns against slippage practically hasn't appeared, except for one model from company Gislaved. It is connected by that in the past 2010 there were very many novelties in models with thorns. In 2011 Tires manufacturers have increased quantity of standard sizes in the novelties announced in 2010. Nokian, for example, has exhausted some new standard sizes in model Hakkapeliitta 7 already familiar to us, Hakkapeliitta 7 SUV, including 245/55R19 for new Toyota Highlander. Has increased type of the size a number and Yokohama in model IceGuard IG35.

Novelties from Nokian

Nokian WR D3 – the winter tire for the Central European climate. It was developed for struggle against slush and elimination of effect of hydroplaning and slash landing. It is intended for quiet and economic style of driving. Possesses raised stability to deterioration.

Cargo tires of a winter season 2011

On the threshold of winter we remind you of necessity of timely acquisition of cargo tires. Installation of these tires in the specialized centers, operation of tires on corresponding shafts of a vehicle, observance of norms of an internal pressure in tires - all it will allow you to use your tires on 100 % and as to secure itself and other participants of traffic.

Not the secret that a large quantity of cargo tires is made in China. The uncountable quantity of new brands dazzles, as color Chinese toys dazzle. But if to toys all of us still can make a complaint on quality cargo tires on workmanship, running characteristics, don't concede adaptability to manufacture of manufacture to well-known European leaders. Many Chinese brands are familiar for a long time already to consumers and have well proved in the Russian market.

First of all it is necessary to note cargo tires Aeolus. Tires Aeolus - the leader on the market. Joint project Aeolus with company Pirelli has allowed to deduce manufacture of radial tires on higher qualitative and quantitative level. During the winter period for regional transportations we recommend model Aeolus HN355. The all-weather tread of the tire provides excellent clutch with road, excellent resistance to slippage and high stability to deterioration.

Shod wheel disks

The second method of manufacture light-alloy disks is the smithery, or as experts speak, hot volume punching. Therefore and shod disks often name stamped (not to confuse with steel stamped). A shod wheel disk

Pluses of shod disks:

At a smithery strength above is reached, than at molding as there is a crushing of grains, their deformation and a pulling in the necessary direction - as a result metal structure to become fibrous. At the expense of it reduction of a thickness of walls of a shod disk approximately on 20 % in comparison with the cast is possible. High strength of a material of disks provides with it good weight characteristics: the weight of a shod disk on 30-50 % is less than weight steel and on 20-30 % of the similar cast. Thanks to high plasticity such disk doesn't collapse after strong blow, and is deformed on similarity of the steel. Stamped magnesian disks possess good corrosion firmness, and aluminum and at all it is possible to use without a paint and varnish covering. In general, the shod disk has incorporated all advantages cast and steel stamped colleagues, thus having got rid of their lacks.

Steel stamped wheels

Most the wide circulation was received by stamped steel disks. Structurally they consist of the disk (plate) and a rim. A disk (plate) stamp from a sheet steel on a special cross-section for ruggedness increase. A wheel tread also stamp from a steel. Both components connect among themselves by means of dot contact welding. After that on a surface put a sheeting (enamel, a powder covering and another). Some cars on the conveyor receive plastic decorative caps for such wheels – in this case wheels are painted by the black. There are wheels of silvery color is more often, is more rare – chromeplated, white and others.
On sale there are steel wheels with landing diameter from 12 to 16 inches, approaching to huge set of cars, - choose! Such wheels on a number of the enterprises of Russia, the CIS countries and the far abroad are made.
Identification mark of steel stamped wheels is similar to identification mark light-alloy wheels.

Automobile wheel specifications

Disk standard size:

5,5jx15 ET45,0 5*108x65,0

5,5 (B) - the width of a rim (it is less than width of a profile of the splint on 25-30 %) is measured in inches.

15 (D) - assembly diameter of a disk, is designated in inches (12 ", 13", 14 ", 15", 16 ")

ET45,0 - The departure, is measured in millimeters.

The departure is a distance between the planes one of which passes on a fastening plane, and the second plane halves a disk. The departure can be positive (ET > 0) if the plane of fastening of a disk is displaced outside concerning an axial plane of section of a wheel. The departure can be negative (ET < 0) if the fastening plane is displaced inside concerning an axial plane of section of a wheel. The departure is peer to zero (ET = 0) if the fastening plane coincides with an axial plane of section of a wheel.

5*108 (PCD) - the Landing aperture, quantity of fixing apertures * diameter of a circle of the centers of apertures, is measured in mm.

For example: 4*98 - for wheels of cars, where 4 quantity of fixing apertures on a disk; 98 diameter of a circle of the centers of fixing apertures.

65,0 (DIA) - the Central aperture, diameter of an aperture under a nave, is measured in mm.

Summer tires - it is time to change the shoes!

Two times a year it is necessary to change tires on the favourite car. It as change of footwear in the winter – winter, in the summer – summer. Time for summer tires has now come. Differences of winter and summer tires as a part of rubber, a framework design, a tread pattern.

Summer tires are used only when on roads any more doesn't remain snow and ice.

At summer rubber the best clutch with dry asphalt, for the account big a useful area of a stain of contact piece.

By manufacture of summer rubber softer rubber which is lost the elasticity at influence on it in low temperatures (below 5-7 degrees) is applied, and it will cause the raised danger on road.

We choose the size of an automobile tire

Standard or increased?

Many motorists thought time and again of what size of an automobile tire to choose for iron "friend". Or to leave standard, provided by factory the manufacturer, or to take something more.
It is natural before asking this question, whether is necessary to find out for itself you wish to keep a guarantee on the suspension bracket detail, established by the manufacturer of the car as the majority of dealers is deprived by guarantees at use of not recommended standard size of automobile tires.

If the guarantee on the car at you already isn't present or you are ready to "change the shoes" before visiting of dealer service in the standard size possibilities of a choice of other standard size of tires and disks will open before you with visiting specialized the center.

To fans of standards especially to reflect there is nothing, after all acquisition of automobile disks and tires big the size, certainly, involves increase in expenses at car service. To admirers not only functionality, but also beauty of the car, direct road to specialized shops on sale of tires and disks.

If on your car it is established as the standard 15 size of rubber its increase at least for 1 size will allow to improve appeal of the car considerably. Naturally, after all in higher «footwear» the car will look much better.

How to buy automobile tires

Tires for the car nearly one of its most important components. Certainly, in the majority of failures drivers are guilty, but tires can become an accident principal cause. Therefore it is necessary to pay special attention on their condition. Tires necessarily should be reliable and qualitative. Therefore on delivery them to shop or destination it is necessary to order an automobile cargo transportation in the checked up company, only in it a case you can be confident quality of delivery of your cargo.

Tires necessarily should correspond to wheel disks. Also presence of identical rubber on all wheels, too the important factor. An indispensable condition – observance of one standard size and drawing!

Rubber is subdivided into two kinds – winter and summer. Speaking about winter tires, it is necessary to note on them presence of thorns. They interfere with sliding. Marks at such tires – M+S (a dirt + snow). Rubber with thorns an ideal variant for driving on crude roads, for example in the country. Summer as it is not difficult to guess intends for all other seasons.

Automobile tires - operation and leaving

Tires are a unique link between the car and road.
Under any road conditions safety depends on a stain of contact rather small on the area. Thus, it is very important to support tires in a good condition and at their replacement to use the appropriate equipment.
The size of tires at the first complete set on your car is defined by designers of cars and manufacturers of tires taking into account all aspects of operation. At their replacement it is not necessary to change the sizes, type, loading and speed indexes, without having consulted preliminary with the expert.

Installation and dismantle of tires

These operations should is made only by professionals with use of the appropriate equipment. Wrong installation can become an accident cause or damages of the tire, the chamber and a rim.
Installation of the tires which are not coinciding on type and the size. Except for special cases and cases of use of a spare wheel, the tires mounted on one axis, should be one type and the size.
It is not recommended, and in some camps even it is forbidden, to mount on a back axis diagonal tires if on a forward axis radial tires are established.

Summer 15 inch tires

Today about 60 percent of the world market of automobile winter and summer tires belongs to "the big three” — to companies Michelin, Bridgestone and Goodyear. These and other whales the industries gradually absorb small firms — during the last years the number the companies in Europe was reduced with 111 to 83. However in the market still there are small independent players who, despite a rigid competition, continue to develop new models of summer tires independently. There are also new marks of summer tires — cheap production from South Korea, Malaysia, Indonesia. Whether it is necessary to save, buying inexpensive summer rubber of little-known manufacturers? And if not to save, what of the checked up marks to prefer?

We have tried to answer these and other questions during the next comparative tests of summer tires.

In the list of participants of ours the test — thirteen import models of dimension 185/65 R15. Half of summer tires already took part in last year's tests is Continental PremiumContact, Goodyear Eagle Ventura, Pirelli P6, Michelin Energy, Dunlop SP Sport 01 and Barum Bravuris. Other summer tires — debutants: Nokian NRHi, Marangoni Vanto, Firestone Firehawk TZ200, Vredestein Hi-Trac, Euromaster VH100, Toyo Roadpro R610, Champiro 65. Additional representation need unless Euromaster (it is a new trade mark of tires which in 2000 was deduced on the market by English firm Avon) and Champiro — tires from Indonesia, which well-known in the homeland, and now appear and in Europe.

Automobile disks (wheels)

Wheels and wheel disks - questions and answers

Why easily floatable wheels it is better, than steel?

With growth of manufacture of aluminum and occurrence of the processing centers under control of computers, easily floatable wheels were widely adopted also their advantages in relation to regular steel wheels usual motorists have felt.

Excellent appearance of wheels. The designer can create, and manufacture - to embody. The technology of molding gives freedom in creation of design of a wheel.

The minimality of a disbalance and accuracy of the adjusting sizes is reached for estimates of accuracy of operational development of compression molds and fur of processing of surfaces of rotation.

Ease and durability of a wheel.

Easily floatable wheels it is easier than traditional steel disks as the alloy basis is made by aluminum - easy, "winged" metal. The concrete weight of a wheel is defined by its design. Durability of a wheel depends on a design, quality of an alloy and performance of technology requirements at each stage. Mechanical properties of an aluminum alloy after a smithery it is better, than an alloy applied at molding of wheels, therefore since the diameter in fifteen inches shod wheels, as a rule, it is easier cast.

Life without thorns

Choosing winter wheels, it is necessary to remember that thorns will be useful only in the event that will be maintained on naked ice and on smoothly rolled snow. Here "claws" are necessary. However it is not necessary to forget that at movement on high speed on pure asphalt in the winter thorns are pressed into rubber, reducing cohesive force of wheels with road. Therefore for speed of 90-100 kilometers per hour coupling thorns of the tire with the cleared away road cloth worsens on 10-15 % in comparison with a wheel without thorns, the brake way thereby increases and stability of the car on a line decreases. Hence, if the car "winters" generally in a city or to migrate on the countries of Europe it is more logical to "put" on it in rubber without thorns. Its high-speed index much above, than at "prickly" tire covers, and noise level of such wheels 10 times less. As their elements – wet and dry asphalt, and also not rolled snow which they perfectly get the flutes.

Michelin Maxi-Ice

In this tire cover it is a lot of strangenesses. For example, Frenchmen have created new model not so long ago, however the name have left that was at its predecessor. Meanwhile Michelin Maxi-Ice bypasses many eminent tires without thorns in a category "the linked properties on ice". The rubber name not "from a ceiling" is taken by the manufacturer. However, there are censures from experts to behavior of this wheel on a winter snow-covered line. Therefore it is not necessary on Maxi-Ice to "lift" to itself adrenaline, as a high-speed index of this tire "Q", that is only 160 kilometers per hour. That, truth, allows the French manufacturer to declare with pride low level of noise published by a wheel. As to drawing of a protector of the given tire it is rather specific, therefore in crude weather to leave on such tire in long road it is not recommended. One more difference of this wheel from other models of the French manufacturer – "elastic enough" drawing of a protector. This new working out of concern Michelin is focused, mainly, on northern areas of Europe.

Winter tires of category SUV

The Finnish company Nokian Tyres has developed the new winter tire Hakkapeliitta SUV specially for drivers. So it or not so, but anyway the first presentation of a novelty for journalists of automobile editions has passed well. Similar actions become already for Nokian Tyres tradition – one year ago Finns represented frictional tires Nokian Hakkapeliitta Rsi. And in it anything surprising isn't present: it is difficult to find the country with more severe weather conditions and that is the most important, with more snow-covered winter roads.

What for off-road car winter tires?

As it is possible to guess from the name of new tires, they are intended for cars of class SUV (Sport Utility Vehicle), promptly extending and in the world to that the certificate – number officially registered off-road car for 2001 - 2003 And if about 10-15 years ago off-road car were used directly and were the working horsies moving with speed, not exceeding 140 km/h today it is the high-speed modern cars which have lost in passableness, but developing speeds over 200 km/h. That is the park has grown not only quantitatively, but also is qualitative. According to the similar car modern tires, with a high indicator of speed are necessary.

Winter tires

Winter tires. A correct choice

So the winter comes, and, hence, any motorist should will take care of a choice of winter tires. In this article we will talk how to choose winter tires that thus it is necessary to consider, the prices for the most popular winter tires and other questions.

All seasonal tires are undesirable

Many motorists believe what to buy all seasonal tires much more favourably. But this benefit consists only in the price. The matter is that summer tires from winter strongly differ: both under rubber characteristics, and on drawing. Therefore in different climatic and weather conditions the same tires will behave differently, sometimes even is unpredictable. Try on summer to leave in ice... Here even matters not wheel thorns (about it we will talk more low). Imagine a pickle, which half - with taste of chocolate. Here approximately and all seasonal tires work. In them developers tried to combine not joint: properties of summer and winter tires.

Automobile tire

Automobile tire — not simply "rubber" dressed on a wheel disk, and a difficult, multipurpose design. A design of radial and diagonal, chamber and tubeless tires for cars, types of drawings of a racetrack of a protector.

Tire basic purpose — to soften pushes and the blows transferred to a suspension bracket of the car, to provide reliable coupling of a wheel with a road covering, controllability, to transfer to road traction and brake forces. Substantially the coupling factor, passableness depends on the tire in various road conditions, fuel consumption and the noise created by the car during movement. Besides, the tire should provide the set load-carrying capacity, reliability and durability.

Tires are subdivided:

Depending on a skeleton design — on diagonal and radial;
On a way of hermetic sealing of internal volume — on chamber and tubeless; as racetrack drawing — road (summer, all-weather), universal, winter, the raised passableness;
On a profile of cross-section section.
