how to choose winter tires, the tread pattern, when to change tires

It's coming to winter, the temperature outside moves to zero, and in some regions of our vast country, already drops below zero – it forces motorists to think about the need to "pereobut" your car for the winter. If you this question began to agitate, then this article is specially for you.

Tires - it is a constant expense motorists.

Winter tires are designed to operate in cold weather (with temperatures not exceeding +7⁰ C). What is the difference between winter tyres from summer?

It is considered that the main difference between winter tyres from summer tread pattern. Actually it's not the main difference. The main difference is the composition of the rubber: ordinary rubber (not winter) has such a chemical composition, which in the cold (at low temperatures) loses its properties.

When to change tires

The official time change summer tires for winter not specified. However, amongst motorists, there are a few rules. First, you should choose the tires before the first snow or first frost. Secondly, "pereobut" your car when the temperature is reduced to +S and every day continues to fall. If to correlate these parameters with the calendar, it is October – November (depending on climate policy).

Types of winter tires

Tires consist of several elements: the protector (main element), base (connects the protector with the inner layers of the tyre, is responsible for reducing the rolling resistance and the reduction of the shocks from the road), a cord of steel (increases the dimensional stability of the tyre, increases resistance when driving and increases mileage). Under the cord is a strip. The bead protects the frame. Wing tape provides smooth cushioning and stability control. These are General characteristics common to all winter tires. In this section you should understand the basic types of winter tires.

Studded winter tires

how to choose winter tires, the tread pattern, when to change tires

These tires are designed for driving on icy roads. If you're on this rubber will ride on the pavement, remember that the grip with the asphalt road surface from studded tyres is poor. Despite this, a large number of motorists prefer these tires.
If You decide to purchase these tires, remember that the first 500 – 1,000 km after the purchase they will need to break in. To do this, you should not develop too much speed (over 80 km/h), exclude sudden (emergency) braking.

For greater clarity, depict the advantages and disadvantages of studded tyres in the form of a table.

Advantages Disadvantages
Great on snowy and icy roads On wet and dry pavement, studded tires lengthens braking distances, reduces nanooptical. In loose snow studded tires "dig" the car is much faster than regular tires.
Braking distance on an icy road is much shorter Studded tyres are more noisy
- Studded tires destroy asphalt surfaces (because of this, some countries have banned the use of studded tires).
- It is believed that studded tires slightly increase fuel consumption.

 

In any case, it should be remembered that the use of studded tires should increase your caution on the road and reduce the speed limit, because the behavior of studded tires on different pavement completely unpredictable. In the absence of modern systems alignment braking and traction on each wheel – the spikes can cause the vehicle to skid much faster than tires without studs.

Nazipovna winter tires

Nazipovna rubber is divided into classes: European and Scandinavian. The European class of winter tires is designed for better grip with wet or snow covered road. The main feature of this tire class is the network of drainage channels in the tread and powerful lugs on it.

The Scandinavian class winter tyre designed for roads covered with snow. It is the winter tires in this class are perfect for Russian roads. These tyres have low tread pattern consisting of dots and rectangles, which provides great traction on snowy or icy road.

For clarity, imagine the advantages and disadvantages in a table.

Advantages Disadvantages
Excellent in dry and wet pavement Compared with studded tires, perform poorly on icy roads
In high temperature rubber, which is made of studless tires, not "floats" and does not reduce control of the vehicle -
Compared with studded tires are distinguished by low noise -
Not surface the road -

 

ABS and tires

how to choose winter tires, the tread pattern, when to change tires

Most modern cars are equipped with anti-lock braking system. That is why many tire manufacturers focus their products on cars with electronic system of exchange rate stability. If the vehicle is equipped with this system, when cornering the best result will be achieved in the case when the tyre tread will be cut by longitudinal lamellae. A similar situation with ABS. For cars with ABS it is best to choose a tyre with longitudinal grooves – best of all they will work when you lock the wheels. If the anti-lock system is absent, the situation is the opposite – when I lock my wheel working transverse to the slats.

Do I need winter tires for jeep

One of the greatest delusions is the belief that all-wheel drive car is much safer in winter than the rear - and front-wheel drive. The refutation of this belief of many motorists, as they say, is written in blood.

The owners (especially novice drivers) of the car with the wheel formula 4x4 should firmly remember the following axioms:

- car with increased ground clearance (clearance) is much less stable on slippery surfaces – this is due, primarily, with the increased windage and reduced aerodynamics;

- four-wheel drive car accelerates better – they inhibit all (ceteris paribus) equally;

- the higher the weight of the car – the more it is inert. In any case, no matter what tires You have installed, what is your wheelbase on a slippery road the braking distance 2.5 ton car will be more than 1.5 tons of car;

- any SUV created for use in off-road conditions, but no ice.

The only advantage an AWD car is a better permeability on the unmade road, in all other typical winter conditions the owner of the SUV should be extremely careful.

From the foregoing it must be concluded that the winter tires for SUV is more important than for any other car, because in winter time jeeps are at an increased risk.

Often the owners of SUVs feel the confusion about my rubber. Protector off-road summer tyres are similar in appearance to the winter tread – it often leads to the fact that motorists are sure their SUV installed all-season tires, suitable for use all year. However, it is not so, this tire (summer) when temperatures fall below zero, it becomes rigid and slides as well as a completely bald slicks.

Same tires on different axis: is it necessary

In traffic regulations it is written that you must install the same tires on the same axle, did not specify neither the drive nor the season. For monoprivodnom car it's a rule yet somehow you can apply, although it should be remembered that different tires (with different tread pattern and state) have different braking characteristics, which will necessarily affect the distribution of braking forces on the axle during braking, thus, the risk of skidding increases.

The opposite situation with four-wheel drive vehicle. In the winter four wheel drive all tires must be the same! Remember that four wheel drive all 4 wheels are actively working continuously (not only on corners). Therefore, the balance of tractive effort on each wheel on a slippery road surface may lead to sad consequences.

Select tires

Is high-speed winter tires (European winter). That tires with high speed index, pronounced "sport" tread pattern. This rubber is only directed. These tires can only be used on dry roads treated.

The parameters of aquaplaning in such rubber is usually high, so getting at high speed in the snow "porridge", most likely, will lead to tragic consequences.

Most of the tracks to the use of such a rubber is not finished, so that the rubber choose for their "iron horses" only motorists who drive mainly on cleared roads.

The next type of winter tires – "off road" tires. A tread of such rubber usually consists of separate elements – cubes, dots, snowflakes, the height of which may reach 9-10 mm, between which are large enough gaps (both transverse and longitudinal). This tire is great for snow drifts and snow "virgin land".

However, on dry pavement, this tire will be "noise", will reduce braking performance and will increase the flow rate. It is this rubber that usually appears in the feedback from motorists, as the best. This is because roads are often not removed properly, which makes city road to off-road. Here and makes this tire.

The next kind of winter tires – snow tires classic. Classic protector – everything in moderation: transverse gaps are average, the height of the elements of the picture – 7-8 mm wide longitudinal grooves. This rubber can be both directed and not directed.

This tire is perfect for a relaxing ride, mostly on asphalt. By purchasing these tires, be aware that too deep drifts, driving at high speed in winter is not for these tires.

I would like to remind all motorists that even the cheapest winter tires are much safer the most expensive summer when you use in the winter. Winter is a very dangerous time for all motorists. The video below illustrates this clearly.
