When we talk about the OEM speedometer, you might think that it can measure the speed from one point to another. However, the speedometer works by measuring the rotation of the wheels, drive shafts and axles. Do you plan to change tires? Whether you want to increase, decrease or increase tire size, there are many factors that should be considered when changing tire size. All of these have different effects on the accuracy of the speedometer.

Then, it calculates the angle of rotation to determine the speed of the vehicle. This is why you must keep in mind when changing the tire size of a vehicle. If the wheels and tires are larger or smaller than the original equipment size, you can change the speedometer reading. For safety, accurate speedometer readings are very important.

When changing the tire size, this will have a certain effect on the speedometer. Tire enlargement or downsizing is a way to replace larger or smaller tires. Due to the large circumference, the tires may cause incorrect speedometer readings. The input speed it displays may be slower than the actual speed because the distance it travels in each cycle is greater than its original tire size. This is another way to reduce the size. Because the circumference is small, the reading speed of lcd speedometer is faster than the actual driving speed. You can use road mileage markers and the exact number of travel seconds to calculate the speed. However, this method is not recommended. In addition to inconvenience, it is also not accurate. If you want a simpler and more accurate method, you can take advantage of this technology and use a tire size and speedometer calculator.
