Lateral Force on a Tyre Calculator

Lateral force (F_y):

Cornering stiffness (C):

Slip angle of the tyre (α):

How This Is Calculated

$$ F_y = C \cdot \alpha $$ where:

F_y = Lateral force generated by the tyre (N)

C = Cornering stiffness of the tyre (N/°)

α = Slip angle of the tyre (°)

Assumptions

The relationship between the lateral force and slip angle is linear.
The cornering stiffness remains constant over the range of slip angles considered.
Tyre characateristics are ideal.
Road surface and load effects are neglected.
