Almost a year ago, Moscow Mayor Yuri Luzhkov has initiated the possibility of banning the use of capital studded tires. His main charge to it - it generates a trackway.
A repair roads in a crisis. On the one hand he is right and the conditions of our city, when the roads around the clock watered the dirtiest, it is not necessary. On the other - our climate is little different from the Scandinavian.
And there, as you know, studded tires is required for use. So let's shall understand all the nuances of the pros and cons of thorns. After all, before the first "white flies" from the sky there are not too imnogo time.
To be honest, a large category of Russian car owners prefer not to bother about the seasonal change of the wheels, all year round riding a "vsesezonke" (two of our capital city does not count, there are ba-alshie money and others like it). And in many provinces and did go on a summer, or on the spikes all year round (see, we know). Of course, every "director himself, but recall that there was nothing truly universal in the technique can not be established. There are only trade-offs ...
So, "universalka» (M + S on the sides) of the complex characteristics of summer gives way to summer tires and winter - winter. Summer tires because of special additives in the rubber compound in the heat does not "float" and less wear. Winter in the cold is not "dubeyut" remain resilient to shocks.
Below -7 degrees Celsius universal rubber in its physical properties comes close to the plastic. What naughty nuances in the technique of driving at the same time may occur, it is clear to any more or less experienced driver.
All well-known manufacturers divide tires for summer and winter. And, on this basis, build its factories manufacturing process. So do not be surprised if at the end of the summer you can not find in Moscow oversize summer tires, and the curtain of winter - the winter. Contract delivery winter tires manufactured between July and December and, accordingly, the summer tires - from January to June.
Extortion inside "a toad" persistently advise you not to spend hard-earned money it is worth to buy winter tires instead of "universalki, you can proceed to the election. Before buying you should be aware that it is recommended to install all-wheel drive cars only tires of the same type and size. For a new tire should be used only to new tubes, tire flaps for the cell type and the same new valves for tubeless. Discs must conform strictly to the size and type of tires installed.
If the owner prefers auto studded tires, then on each axle is recommended to install tires with the same number of spikes.
On what tires - with or without spikes - is better for the winter, conventional wisdom does not exist. And that and the other tires have both advantages and disadvantages.
The main advantage of non-studded, but winter tires are considered good indicators of cohesion in the dry asphalt and snow. But these tires have a significant disadvantage. At the bare ice on the background of spikes, they look pretty pale. Latest manifest themselves only on the ice and snow thumb. But on pure asphalt spikes at times may work as skating on ice.
In the city of periods when the asphalt is covered with a crust of ice, occur less frequently than the days of relatively dry asphalt. On the other hand, no one can guarantee that it is on the ice you do not find yourself in an emergency. Therefore, in some Scandinavian countries in winter is forbidden to ride on cars with non-studded tires.
In continental Europe, on the contrary - it is forbidden to ride on the thorns, and even if you drive into the mountains, then hire a car for this event will be the chain (for example, Switzerland, France or Germany), at one time were sold in the USSR. If we are "studded", then on all four wheels at once. Half-measures such as "spike" from the front or just behind - typical provocation accident.
The front wheel drive car tires on the front axle improves the patency and facilitate the acceleration. But on a slippery road with gentle braking and even the sudden discharge of gas when the studded tires will slow down more effectively than non-studded set back, the car begins to turn the stern forward.
This is especially dangerous in the turns, even not particularly sharp. On rear wheel drive car with studded tires installed on the drive axle is also being addressed with the cross and start from place and when braking the machine is not inclined to turn. However, it will be bad braking on slippery roads. The fact is that under braking the front axle loads increased, and at the rear - is reduced. Therefore, the "spike" on the rear axle does not help the car with a classic drive faster to stay.
For the first time confronted with the choice of a particular dimension of tires, many motorists vague idea that, in fact, mean the alphanumeric "murals" on the sidewalls. For example, abracadabra-type 175/70 R13 82T means the following: 175 - tire width, 70 - the height of its bumper in the percentage of the width (70% of 175 mm was 122.5 mm), R - radial tire structure, 13 & mdash diameter of the disc wheel in inches, 82 - Index of allowable weight load on one wheel, T - speed index.
For the vast majority of drivers than the diameter of the disc, the main criterion when choosing a tire is the width of the wheel.
Increasing the width of the tire increases the contact area with the road wheels. This improves braking and acceleration, especially in cars with a powerful engine. The machine runs better turning at high speed. The wider the tire, the more expensive it is, if only because of its production went more rubber.
The increase in weight of rubber significantly increases fuel consumption, especially for cars with engine capacity of about 1.5 liters. In addition, the wider tires, the more it is subject to the effect of hydroplaning when the car loses control during insertion into a puddle or a snowy mush.
When installing new tires to make sure that inside her there was no foreign material or liquid. For example, water, sometimes condensing in the compressor, which pumped up the wheel, it may well be inside the bus. At least it threatens irreparable imbalance of the wheel.
It should avoid setting the different types of tires - it affects the stability of driving. If you install snow tires, often with high profile, recommended check, whether they relate to the car body, especially at the extreme positions of steering wheel.
If you overdo it with the height or width tire on turns or bumps, the wheel will be "milled" wheel arches. While plans remain Luzhkov, plans, and this winter we'll just hold out. And on what specific tires you decide.
