Travelled Distance :

To make this compute, we actually need the reference of a Wheel.

We took this reference : 215/55R16/93V

16 is the width of the rim and a bigger rim will cover a longer distance than a smaller one

So with the same speed, a car with bigger rim will make less Wheel rotation to drive 100 meters.

Then we calculated :

2xπx27,5= 173cm and after dis, the number of rotation of the tire, we will consider that one rotation equals 173cm and with this we’re going to divide 100 meters by 173 and it equal to 58

58 is the number of rotation of a Wheel with a radius equal to 27,5 cm
