	Diameter of disk, mm (C)	0	0	0
	Outer diameter, mm (D)	0	0	0
	Changing the road lumen, mm			0

On the website of the online store, the site has a convenient tire calculator, which allows you to easily calculate the changes in the wheel parameters when switching to another tire sizew. With this online tool, you can calculate the external measurements of the wheel, clearance (road lumen height), calculate the speedometer readings and other characteristics.

With the onset of the new season, each responsible car owner considers it necessary to change the rubber in accordance with the time of the year. Optimal option There will be a tire of the size that the automaker recommended for concrete brand car. In cases where this is not possible, deviations are allowed in a diameter in a 2% range.

Replacing rubber requires a serious approach. Selecting new tires and discs, it is necessary to take into account such indicators as:

• tire width,
• profile height
• inner wheel diameter,
• permissible speed indices.

The incorrectly selected tires can cause malfunction of the car, increasing the fuel consumption, deterioration of comfort when driving, as well as cause problems during the vehicle inspection in the traffic police.

How to make tire calculation?

To pick up tires required sizeYou need to use the tire calculator, with which theoretical dimensions are determined. All measurements are carried out in millimeters, and the speed in km / h. To make a calculation, you should enter your auto tire parameters in the appropriate line. Then enter dimensions new tire And the disk that will be installed. After specifying all the parameters, the table below appears information about changes in the width of the tire and the height of the profile, internal and external diameter, the difference in speeds (real and speedometer indications).

What to pay attention to the selection of tires

• Installing tires and disks non-standard size It can lead to damage to the tire itself, damage to the disk and a decrease in the operating characteristics of the car. When choosing rubber, it is better to rely on the recommendation of the automaker.
• If the wheel disk diameter is larger, then in this case, the load on the suspension may increase. To preserve the former diameter of the outer wheel, the profile height indicators should be reduced.
• If you select tires with a highly enlarged profile, you need to be prepared for the loss of quality control by car. The tire can touch the body and suspension, which will lead to rapid wear.
• Even with the most insignificant difference in the speedometer and in reality, the error can grow at times with raising the speed, which makes the ride unsafe.
• Narrow or too wide discs can cause tire deformation. This, in turn, will lead to premature wear and worsening performance.

Car tires are an indispensable components of any car. They are able to ensure safety on the road, as well as the implementation technical characteristicswho were originally declared by the manufacturer. Every year, drivers need to change summer tires on the winter and vice versa. It is recommended to select tires with the sizes that were provided by the automotive company for a particular autocar model.
Today, the automotive market offers a wide range of tires that are produced. different manufacturers. Among themselves, they differ not only by manufacturing materials and design, but also sizes. Each car model has its own type of tires that are optimally combined with each other.
The sizes of the tire are implied, as a rule, three parameters are height (distance between the inner wheel disk Both the ground), the width of the tread and the diameter of the inner hole (which is placed in the disk). It is worth noting that the manufacturer when determining dimensions automotive tires It takes into account their mass, craving, power, width and purpose of use. If you even make a minor deviation of the sizes of the tires from the standard, it can lead to a variety of changes, both positive and negative. For example, such as comfort during a trip along the highway or dirt road, readings on the speedometer, fuel consumption and much more. It is for these reasons to change the factory sizes of the tires, it is necessary to approach special attentionbecause consequences can be unpredictable.

What is a visual tire calculator, and why is it needed?

Now it is easy to determine the size of the automotive tires sufficiently. Just need to use a visual tire calculator. With it, the driver will be able to provide all the nuances to avoid trouble in the future. Also, the calculator will allow you to figure out a few options to make the subsequent purchase correctly. This application shows the results in online mode, so you can get the result in seconds. Also, the tire calculator will give the maximum accurate answer, taking into account the readings of the speedometer, fuel consumption, noise, conditions on the roads, etc. The driver, first of all, needs to be focused on the manufacturer's recommendation, and select tires depending on the car model, as well as factory and recommended sizes .

Tire calculator functionality

Help with selection of tires suitable for a specific car in size and characteristics, the Calculator of the tire selection will be able. The service owners of the transport are serving when it is time to replace rubber and discs on the vehicle. In order not to spend time on meaningless "re-overwhelms", checks, use the offered online service. The capabilities of the tire calculator:

• you can calculate the size of the autoresine;
• the service provides different parameters - wheel diameters, changes in the height of the lumen between the road and auto (clearance), the expansion of the gauge;
• assistance in the transfer of inches to millimeters Ilfi on the contrary, the use of the American and European dimensional table.

Tire calculator It was designed to accelerate the selection of rubber, making the procedure at times easier. Since each owner of the car faced the difficulties of choice, online calculators were very quickly gained popularity from users.

How to use a tire calculator

There are several tips that will help to use a tire size calculator for destination. Step-by-step instruction Consists of the following steps:

1. The form you will need to enter the size of the tires installed on the car, as well as those that would be installed.
2. A special table with the results of calculations will appear before the user. From these data it will be possible to find out which autoresina is necessary for specific transport.
3. After selection, the tires can be transferred to the calculation of the size of the disks. Here you will need to set the exact data - the maximum / minimum width of the disk installed on the car. All calculations service will perform automatic mode.
4. If you need to translate inches to millimeters, you can use the online converter. This action will allow you to find analogues with American sizes and with European. Comparison through the tire calculator will be as accurate as possible, since all the necessary information is made to the database of the online service.

The total procedure for selecting is very simple, but from the owner of the car it will be necessary to introduce initial data. Parameters must be as accurate as possible so that there are no errors or inaccuracies in subsequent results.

You can use such a service on our website. The program is in free access, anyone can produce settlements in a few minutes. To simplify the process of use, it is worth using the instructions.

When choosing discs, it is obvious that you need to pay attention to their parameters. At the same time, in addition to the technical parameters that we consider below, there are also structural and aesthetic parameters.

Divided into cast, stamped and wrought. Each type of discs has its advantages and disadvantages. Cast possess a smaller weight, reduce unsappressible masses, improve appearance car. Stamped the most cheap, and forged the most durable and at the same time lung.

In addition, it is important that the design of the discs does not prevent them from installing on your car. And it's not in the inconsistency of the technical parameters that can be perfectly approaching your car, and in constructive features disks. There may be a situation where discs may touch brake mechanisms, Standard bolts may not fit into holes, etc. For this reason, before buying, you must make sure whether the discs are suitable for your car model.

Now let's turn to the labeling of the disks that describes technical specifications disks, i.e. The conditions for their applicability.

An example of marking: 6.5 14 4 × 100 ET45 D54.1

Here digit 14. denotes diameter disk In inches and is the main criterion for the preliminary estimate of whether the discs are suitable for your car.

6,5 - this is disc width in inches. In order to correctly assess the necessary width, you need to refer to the operation manual, where the range of supported values \u200b\u200bis specified. The choice within this range is carried out on the basis of which rubber you are going to install on the disk. The rule here is a simple - the rubber width should not be more than 30 percent more than the width of the disk, and, accordingly, in no case is no less, since in this case the contact stain will not match normal conditions Operating tires.

Two digits separated by a multiplication sign (4 × 100) indicate fixing discMore precisely on the number of bolts and the diameter on which they are located. This figure is extremely important, as even with a difference in 1- 2 mm Disks do not sit on the hubs.

The following designation (ET45) indicates wheel departure. Roughly speaking, this is the distance between the hub (or rather the dialing plane of the disk) and the middle of the disk. Departure affects many pendant kinematics parameters, so you need to adhere to the values \u200b\u200brecommended by the manufacturer, not fond of "remote" discs. In this case, controllability suffer greatly.

The latest numbers (D54.1) indicate the diameter of the board (center) of the disk. This situation may occur that this value does not match (will be greater) the value specified in the vehicle manufacturer specification. The fact is that many manufacturers of cast drives are used to center the transition rings on the hub, making the larger diameter hole. There is nothing terrible in this.

It should be noted that all the technical parameters of the disks are standardized for all types of discs. Therefore, if you decide to move from stamped discs on cast or with cast into forged, you can safely use the old disk as a sample to select a new one.

Such a calculator may need if you want to install instead standard tires or disks their counterparts, but already another size. With it, you can visually submit dimension changes and then interpret them to a particular car. At the same time, the calculator is not a means of selection of tires and disks, since it does not contain the database by manufacturers.

When replacing disks and tires, taking into account the geometric data obtained from tire calculator, it will not be superfluous to make several measurements. First, the distance from the suspension to the surface of the wheel with inner, as well as from the cup of the shock absorber to the surface of the tread. Secondly, from the wing, as well as steering pulls to the surface of the tread. In this case, the geometric parameters of the new wheel assembly should not be much higher than regular tires and disks. Otherwise, the unstable behavior of the car is possible.

Several basic rules that need to be remembered when replacing tires and disks.

1. Tread summer tires Standardly has a depth of 0.8-1 cm;
2. Installing larger diameter discs than regular, it is necessary to reduce the departure value - for each inch height of 3 mm departure;
3. Often the hub holes on the disks that are non-original, have a larger diameter. Therefore, when they are installed, you need to use special rings for fixation;
4. In the case when the hole on the disk is less than the pittal fasteners, it is strictly forbidden to reassure them, as well as to heat the hub itself;
5. The correct selection of non-original discs using a calculator will allow saving the driving characteristics of the car;
6. If you are not confident in compatibility of tires or disks with your car, do not install better, or contact your specialists.
