The first thing to determine before buying car rubber is the diameter of the wheel. The correctness of the movement of the car and its stability on the road depend on how correctly this will be done. The diameter of the wheel is a composite value, so you need to be very careful about the calculations.
Instructions
Step 1
The diameter of the wheel is calculated using a simple formula: add the diameter of the rim to the double height of the tire's cross-section. This calculation method is only used for passenger cars.
Step 2
Measure the diameter of the wheel in the usual way - using a tape measure. Measure each of the parameters of the above formula separately. Then convert the resulting values into inches (since it is in them that the diameter of the car wheel is calculated). You can do it like this: divide the resulting number by 2, 54. Then add up all the values that you got when measuring, in inches. This will be the diameter of your wheel.
Step 3
You can simplify the math and use a simpler formula. To do this, you need to add 20% to the number denoting the width of the rim, and you just get the width of the entire wheel. In cases where the tire is narrow, the difference between the total wheel width and the rim width will be 15%.
Step 4
Experts do not recommend greatly increasing the overall diameter of the wheel - a maximum of a couple of centimeters. After all, that wheel, which is much larger than the norm in size, will crush against the thresholds of the car and interfere with movement. In addition, he will have practically no grip.
Step 5
If you want to increase the diameter of the disc, then choose a rubber that is slightly narrower than standard. However, as the width of the tire decreases, do not get carried away either, otherwise the tire will not withstand the load imposed on it. Therefore, try to keep the balance between the overall diameter of the wheel and the rim as much as possible.
Step 6
Of no small importance in a car wheel is also such a value as the diameter of the rim. Remember, the parameters of the wheel at this point can range from 10 to 23 inches. Small indicators are usually inherent in motorcycles and mopeds. Large ones are used for powerful vehicles.
