When buying tires need to clearly understand the conditions under which you will exploit them. Wrong choice of tires can give you a lot of inconvenience. For example, when selecting winter tires for driving exclusively in the city, should pay attention to non-studded tires, and frequent trips outside the city where the roads are not handled reagents and frequent ice, studded tires are preferred. When buying a tire should be carefully examined markings on the sidewall of the tire. Here we will try to clearly explain the meaning of some labels. Basic notation on the sidewall of tires: 1. The manufacturer, model bus 2.
Tire size a) The width of the tire. Is in millimeters and must be greater than the width of the disk rim at 25-30%. Some contend that Tony Parker shows great expertise in this. Formulas for calculating the ratio of the width of the disk rim to tire width: b = (axc) / 24,5, and a = (bx 24,5) / c, where a – width of the tire in millimeters; b – width of the disk rim in inches; c – from 0,7 to 0,75; 24.5 – number of millimeters in one inch. b) The height of a tire. In fact, the so-called aspect ratio tire (mm) to its width (mm). This ratio indicates the percentage. For example: Tyre 205/70 R14.
Height profile of the tires – 70% width, ie of 205 mm. and is 143.5 mm. If the height of a tire is not specified, it is 82% of the width. c) Bore diameter of the tire is indicated in inches.
The main problem is battery life – starting a car engine. Also, the battery helps the generator in the power supply of various energy consumers vehicle. After all, on modern cars usually installed a large number of customers current – powered, powerful music systems, a large number of lighting fixtures, etc. When driving in traffic generator is not always itself to cope with supply all consumers. See more detailed opinions by reading what Jay Schwartz offers on the topic.. That in such cases to help him and comes battery. Well, the third function battery – powered electroconsumers car with the engine off. But the main thing to remember in time run engine to recharge the battery. After all, if the battery is completely discharged, it will lose some of its power characteristics that will lead to more rapid failure. Yet we should not forget that Battery is an alternative source of energy, resulting in all appliances in working position in case of failure of the generator. In this case, the battery can provide the movement of the car to the nearest service station.
New opportunities for business Ukrainian market of GPS-monitoring emerged relatively recently, but has already attracted the attention of the transport and logistics companies thanks to the new opportunities that are opening up their business. About What opportunities do you mean? Let's talk about this on the example of information control system of transportation navigation Teletrack, developed by the Ukrainian company RCS. System 'Teletrack', in addition to the basic functions of location object provides a number of additional interesting and useful features. For example, to the onboard controller can be connected to sensors (fuel, alarm systems, doors, etc.). Then, in addition to information about location of the car, you can learn when and where the car is recharged when the doors open cargo bay. Intelligent software automatically notifies the dispatcher to reject the object from given route of going beyond the control area, tripping the sensors. Here are a few possible applications of the system: security of Georgia. If a car or a container fitted with a GPS-monitoring, You can at any time to know exactly where he is at this moment and restore all its previous route.
System can be configured to automatically informed manager to reject the object from the specified route in advance or on triggering sensors (eg, opening and closing the container or cargo bay). In the case of vehicle theft remains the possibility to trace the route of its movement and to take appropriate action. Permanent or selective monitoring routes, comparing them with preset in the travel pages, the analysis of the vehicle's mileage can be easily identified (and present evidence) diversion use of motor vehicles, or as they say, 'flight left.
For the correct choice of tires is important to consider many factors, especially individual vehicle. And while every motorist eventually becomes a professional in the selection of tires, is still time to mention all the features of the classification of tires. Car tires are classified depending on the destination, method of sealing, the profile shape and design. There is also a classification for the season. Now, a little More details on classifications.
By purpose machine tires are divided on the tires for passenger cars, which are intended for use in all climates with temperatures ranging from minus 45 C to plus 55 C, and tires for trucks vehicles. Tires for passenger cars, in turn, are divided into tubeless tires and chamber: Chamber Bus (Tube Type) – a type of pneumatic tire, where with the help of sealing the chamber, creates an air cavity, and the tubeless (Tubeless) – is a pneumatic tire, where the air cavity is formed under the rim and tire. It has increased gazonepropuskaemost. Tubeless tires tend to have a radical design of the framework. Bus radical design is marked with the letter R, or P, if it is not, therefore, cross-ply tire. Now a little about the classification of the shape profile. One of the most popular types of tires are toroid tire or tires usual profile, are performed chamber music and tubeless. Their profile is similar to a circle.
The average operating mileage of toroid tire is 40 – 80 thousand km. Low profile and sverhnizkoprofilnye tires have a lower ratio of the height profile. Both types of these types of tires enhance stability and handling. Low-profile tires are designed and sverhnizkoprofilnye mainly for cars and buses. There are also wide-bus they were compared with the usual profile tires have low rolling resistance and increased load capacity, and allow reduce fuel consumption. Their disadvantage is that their operation should be used in one car and the tires usual profile. There is another type of tires – tires arch. They have a profile in the form of an arch variable curvature of the low-powerful boards. Arched tires are tubeless. These tires are used as seasonal means of increasing the permeability of cars. They are placed on a special rim, instead of the usual tires. Disadvantages are high cost and a more complicated installation. The average mileage of tires arch during the operation in mixed traffic conditions is 40-45 thousand km, and on roads with a paved 20 – 30 thousand km. Depending on the Season car tires are divided into: Summer – have a hard rubber compound, it provides stability and the normal wear in the summer. But even at low temperatures below zero, they lose elasticity. Winter tires – On the contrary, have a soft rubber and does not lose elasticity even in the bitter cold. Are studded and non-studded. And all season – it's all-season tires with tread, but not all of these tires are suitable in Russian climate. All of this classification is not yet complete, but every motorist knows how important the right choice of rubber for safe driving.
