Car tires, regardless of brand,are one of the most important components of driver and passenger safety. Worn or out of season picked up ramps can cause not only problems with the management, but also cause traffic accidents.
All tires for seasonal use are divided into the following types:
The last three types of stingrays are most commonly used.in motor sports, and motorists are used very rarely. Therefore, we dwell on the most familiar tires for us, which can be purchased at any specialized auto shop.
Summer and winter tires are significantly differentfrom each other in composition, density and porosity. In addition, they have a different pattern and tread area. Summer tires have a more rigid structure that provides maximum grip. While driving between the slope and the road surface, a certain friction occurs, due to which the temperature of the tires increases. Because of this, the rubber becomes softer and more pliable.
Usually summer skate protector is uncomplicated.picture. Its main task is to divert water when driving on a wet road. Due to these properties, summer tires are absolutely not suitable for use at low temperatures.
This kind of stingrays is intended for those who do notI want to wonder about when to put winter tires, and when - summer. All-season tires make it possible to use them in different temperature conditions. However, this solution involves more disadvantages than advantages.
There is only one plus in the application of the all-season - replacementsummer tires for winter is not required. In return, the driver will receive year-round tire wear, additional noise when driving on dry and hard roads, unstable behavior of stingrays in high and low temperatures. In addition, motorists who prefer an aggressive way of driving, will have to abandon the abrupt start and braking.
All-season tires are suitable for motorists, notusing personal transport in the winter or careful drivers who do not exploit their “iron horse” for long trips in extreme conditions. In this case, the change of summer tires for winter, and vice versa, will simply be unjustified.
Winter tires have a lower density due to its porosity. It is much softer than summer, which allows you to significantly increase traction with the coating, even on an icy road.
The tread of winter tires has a more complex pattern,giving the opportunity to remove from under the wheels not only water but also snow slurry. Its increased area is also designed to provide maximum grip.
Winter tires can be divided into two types:studded and "sticky". The first ones are a slope, on the working surface of which metal spikes are placed in a special way. These tires are ideal for driving on snowy roads and off-road, but on a wet or icy surface it is better not to use them. The test of winter tires, equipped with spikes, in such conditions showed a significant increase in stopping distance due to a decrease in the quality of adhesion to the road.
The best solution for a snowless winter and for driving inthe city are velcro. This type of tire is also called friction. Their feature is a specially selected rubber compound that allows to adapt to different temperature conditions. A small tread applied to the entire working surface absorbs and drains water, as if sticking to the road surface. Brake test of winter rubber-velcro and studded tires, carried out on ice at a temperature of -150C, showed that friction chutes definitely have an advantage. However, with an increase in temperature to 00With win spikes.
There is no definite answer to this rhetorical question. Some car owners do it, focusing on the beginning of the heating season, others - on the transition to winter time, others are waiting for the first snow.
The best option for changing tires is to stabilize the average daily temperature at + 5 + 70WITH.With a further cooling, it is not safe to ride on the summer slopes - they become rigid, and their grip deteriorates. Tire manufacturers agree. Such a temperature, according to their recommendations, is a signal to change the rubber.
And in no case should not wait until the snow falls. First, it is an additional danger factor, and secondly, the queues for tire during this period will not allow to do it in one day.
For novice drivers, it will be important to find outonly about when to put winter tires, but about some of the features of its operation in cold and bad weather. In addition to the fact that tires become tougher with decreasing temperature, the pressure in them drops. This is due to the physical ability of any substance to narrow and expand. Air in the tires is no exception. With a decrease in temperature, it is necessary to check and, if necessary, pump up the ramps. Low tire pressure not only impairs the running ability of the car in winter, but also leads to excess fuel consumption.
When installing winter tires need to payattention to the degree of wear. Usually in front wheel drive vehicles, the front tires wear in the middle and the rear tires on the sides. In order to ensure uniform production, it is recommended to change their places every 8-10 thousand km.
With the end of winter, some motorists are in a hurrychange tires for summer tires, for fear of their rapid wear. Indeed, soft winter tires wear out very quickly when driving on asphalt pavement under the influence of increased temperature caused by friction. But here it is necessary to take into account that the weather conditions in the early spring in our latitudes often change, and even in April there are frosts, not to mention the March snowfalls.
Часть автомобилистов предпочитает использовать two sets of disks: one with winter tires, the other with summer. This is convenient in its own way, and you can change the wheels yourself. Firstly, in the period when it is necessary to change the tires, there will be no question about registering for tire service and paying for service stations. It is enough to have on hand a jack and wheel wrench. Secondly, the tires worn on the wheels will not be deformed during seasonal storage.
But here there are some nuances.Such a decision will be correct under certain conditions. The first is that when installing wheels in a set, they should be carefully examined for the presence of deformation. A bent or cracked disc can cause an accident. Second - the wheels need to be balanced. Otherwise, problems with the chassis of the car can not be avoided. Imbalance of the wheel during rotation creates a vibration that will gradually destroy the hub bearing. And, of course, do not forget about tire pressure. If its performance is insufficient, you need to use a pump or compressor.
Without discs, tires are also perfectly preserved.It is enough to put them vertically on the floor, pre-laying it, and your rubber will lie quietly until its next season. In no case should the tires be laid flat horizontally on top of one another or suspended.
Also, do not store ramps on the street underopen sky. The sun and subzero temperatures have a detrimental effect on rubber. If you do not have your own garage or other similar premises, it is better to use rubber storage services on special services. There, in addition, the condition of the tires will be checked and will help “change the shoes”.
Whatever tires are installed on your car, do not forget about the speed limit. On the winter road, it’s more important not the quality and condition of the rubber, but the care and caution of the driver.
