Rolling Resistance Calculator

Find the rolling resistance force on a wheel.

Rolling resistance (N) 15

Formula: F = Crr · N

Step-by-step with your numbers:

1. Values used:

2. Rolling coefficient Crr = 0.015

3. Normal force (weight) = 1,000 N

5. Rolling resistance = Rolling coefficient Crr x Normal force (weight) = 0.015 x 1,000 = 15N

Did we solve your problem today?

Rolling resistance is the force resisting a wheel rolling on a surface.

The math behind it

F = Crr·N. Typical car-tyre Crr is around 0.01–0.015 on asphalt.

Crr 0.015 on 1000 N → 15 N of rolling resistance.

Why are bike tyres pumped hard?

Higher pressure lowers Crr, reducing rolling resistance.
