حساب تغيير مقاس الإطارات

The diameter of the rim and the tire must collectively maintain the same diameter of the rim and the original tire of the car so as not to affect the car negatively.
This will also ensure that the height of the car remains largely unchanged and does not prejudice the safety of the car.
When changing tire sizes, it is recommended to stay within +/-5 mm of the original tire diameter/height.
Simple application for calculating the amount of change in tire height size when adjusting tire sizes.
