The diameter of the

**wheel**is calculated by a simple formula:**the diameter**of the disk to fold double-high profile tires. This method of calculation is used for cars only.2

Measure

**the diameter of the****wheel**in the usual way - with a tape measure. Each of the parameters above described formula measure separately. Then, the resulting values translate to inches (because it is in them and calculated**diameter of**a car**wheel**). You can do it like this: the number you divide by 2.54. Next, add up all the values that you got when measuring in inches. This will be the**diameter**of your**wheel**.3

You can simplify mathematical calculations and use a more simple formula. To do this you need to the number denoting the width of the rim, add 20% and you just get the width of the entire

**wheel**. In cases when the tire is narrow, the difference between the total wheel width and the width of the disc will be 15%.4

Greatly increase the overall

**diameter****of the wheel**experts recommend a maximum of a couple of inches. After all, the wheel that far exceeds the norm in size, will be scraping along on the rapids of the vehicle and prevent movement. Besides, he has almost no coupling with the road.5

If you want to increase

**the diameter**of the disk, choose tires a little small. However, with the reduction in the width of the tires also do not get carried away, otherwise the bus will not sustain its load. Therefore, try as much as possible to strike a balance between the overall**diameter**of th**wheel**and drive.6

Of great importance in the automotive wheel has such a value as

**the diameter**of the rim. Remember, the settings**wheel**on this item can range from 10 to 23 inches. Small figures usually inherent in motorcycles and mopeds. Used for large powerful vehicles.Useful advice
