The size of the wheel - a very important factor when choosing a car tire. Choosing the right tires makes the car a good road holding and enhances driving safety.

However, many motorists simply do not know how to determine the size of the disk and the tire.

To get started, try to determine the width of the wheel. For the calculation can take advantage of the "people" formula, if the width of the vehicle wheel tire tread take 20%, then you will get the width of the wheel disk. For example, if tires have is 255 mm, the width of the disc is 255 mm - 20 mm = 204%. To convert this value to centimeters, divide that number by 10. We obtain 20.4 cm. Then divide by 2.54 to get the size of the width of the disk of 8 inches (in them the values ​​of the wheels are calculated mainly). If you want to put a disk wider or narrower tires, remember that the recommended maximum difference between them is only 15%.

To help you determine the size of its wheels onavailable options, pay attention to the label directly on the lid. As a rule, the amount will be listed on it, which is indicated as follows: 6 x 14, 6.5 x 15, etc. Here, the first number indicates the width of the rim in inches and second number - the rim diameter, again in inches. Based on these figures, you can easily determine the bus what size you need to purchase.

When choosing the wheel size, remember that fordiameter of the rim of their rates vary on average from 10 to 23 inches (depending on the type of vehicle). The width of the rubber profile may vary between 2.3 and 4 inches. The smallest of these indicators are suitable for motorcycles, scooters and scooters, and the largest - for the transport of more powerful.

Also, if you decide to replace your hard disk or on rubberhigher, remember that in this regard, should change a few parameters, such as flight. Its size by increasing the wheel diameter must decrease. Moreover, it is desirable to do so by the formula: 0.5 inch = 6.5 mm minus the distance from the axis of symmetry of the wheel disc to the landing attachment to a hub plane.
