@Maveriq ok literówka z tą 12"
Chodzi o to że masz dwa koła np 22" i 25". Masz licznik skalibrowany na 5" od środka koła dla koła 22". Jeżeli zamontujesz taki licznik na kole 25" i 5" od środka, będziesz miał złe wskazania. Obliczenia jak w [LINK]
So to summarize, if the speed of rotation of the car's wheels does not change, the speed of the car is directly proportional to the wheel's radius. Larger radius means higher speed, and smaller radius means slower speed. Of course, you cannot make a car with a top speed of (say) 100 MPH, do 200 MPH, just by putting wheels that are twice as big on it! The motor has to have a lot more power to keep the larger wheels turning the same speed as before, because higher speed (no matter how you achieve it) requires more power.
