With approach of spring motorists get up before a problem of a choice of summer tires for the car. After all safety of the driver and passengers in many respects depends on quality of rubber. Road conditions in the winter and in the summer considerably differ. Therefore use in the summer, as well as is unsafe in the summer winter. Will help to understand subtleties of a choice of summer tires InfoAdvisor.net to drivers in this article.
Why it is necessary to change rubber for the summer
Let's begin with that we will solve, whether it is worth "changing" the car in general. The matter is that besides that winter and summer tires have different drawing of a protector, they are made of rubber of different quality. Winter tires are made from softer grades of rubber. Therefore during a summer heat, being softened, they lose the operational qualities. Summer tires – on the contrary, more rigid. As a result in winter frosts they become too elastic to provide normal coupling of wheels with a road surface.
Exist, however, and all-weather tires which in principle are serviceable during any time of year. But they conceal in themselves a quantity of "reefs". First, such tires cope with the task obviously worse, than specialized, intended for a certain season. Secondly, buying such tires, it is worth paying attention to, whether they are made for the countries with hot climate, where an air temperature difference in the summer and in the winter not such considerable as in midlatitudes.
From here conclusion: lazy and economical drivers can manage all-weather rubber. And those who does not want to save on safety, should reflect on change of rubber at approach of a warm time of year.
Drawing of a protector of tires
Protector drawing – one of the major factors which are responsible for coupling of the tire with the road. The best coupling will be provided by the tire having asymmetric drawing. The more drawing depth, the better we operate the car will be on the wet road. Besides, often apply special flutes which as if push out water from under wheels during the movement on summer tires. Usually on such rubber there is the corresponding marking of Rain - "rain", or Aqua – "water". And here tires with V-shaped drawing of a protector, on the contrary, are suitable for dry asphalt better. However both that and other drawing is acceptable for summer tires.
Standard size of tires
In technical documentation your car it has to be specified, what standard sizes of tires are suitable for use on it. Often some options of standard sizes can be specified. In this case it is possible to remember the rule: it is better to put narrower tires, and in the summer – wider in the winter. You should not recede from standard sizes of the tires recommended by the producer. First, in this case safety of operation of the car decreases. Secondly, if length of a circle of the used tire differs from standard, it will affect the accuracy of indications of a speedometer (speed and a distance in kilometers will be incorrectly considered).
Distinction of tires depending on loading and speed
Among other things tires differ with a speed index. The index of loading and speed is designated on a lateral surface of the tire and has, for example, the following appearance: "90T". It is possible to choose suitable summer tires by means of the following tables:
|Max. loading (in kg)||335||387||450||515||600||690||800||925||1060||1215||1400|
|Max. speed (km/h)||100||110||120||130||140||150||160||170||180|
|Max. speed (km/h)||190||200||210||240||> 210||270||300||> 240|
Therefore, 90 means load of one tire of 600 kg for our example, and the letter "T" corresponds to the maximum speed of 190 km/h. Certainly, if your car is not capable to gather speed more than 150 km/h, it is not necessary to buy expensive summer tires with a high index of speed.
Ability of rubber to balancing
The important characteristic of both summer, and winter tires is possibility of their balancing. If the tire is not balanced on disks, defect-free, it should be returned to the seller as rejected. The same can be told if balancing requires rather large number of small weights. For anybody not a secret that the unbalanced tire not only causes a beating at a high speed, but also wears out quicker.
What summer tires it is better to buy: new or second-hand?
You should not sweep aside at once possibility of second-hand purchase of summer tires. It is better to get the good tires having small degree of wear often, than new, but not best quality. Of course, the summer tires which were in the use will serve less new, but all the same it is possible to save on it not bad.
And time the speech came about economy, it is necessary to consider one more moment: tires of the famous, "untwisted" producers are much more expensive, than their colleagues made by less well-known firms. And here quality often is almost identical. Chasing a known trademark it is necessary to remember that it is necessary to pay not only for goods, but also for a brand. InfoAdvisor.net would also like to dispel myths about the Russian tires, opinion that domestic much more lag behind from foreign - far from truth. But unambiguously here it is impossible to advise any tires all the same, it is only possible to use own or others experience, that is councils of the acquaintances using summer tires of different producers.
Well also you should not forget that on one axis it is impossible to put tires of different types, and it is desirable that all 4 tires were identical. Besides, choosing summer rubber, it will be reasonable to study reviews and tests of tires of various brands and producers.
