A method for determining a tyre normal force range (Fz,min, Fz,max) of a tyre force (Fz) acting on a vehicle (100), the method comprising; obtaining (S1) suspension data (310) associated with a suspension system of the vehicle (100); obtaining (S2) inertial measurement unit, IMU, data (320) associated with the vehicle (100); estimating (S3), by a suspension-based estimator (330) a first tyre normal force range (Fz1,min, Fz1,max) based on the suspension data (310); estimating (S4), by an inertial force-based estimator (340), a second tyre normal force range (Fz2,min, Fz2,max) based on the IMU data (320); and determining (S5) the tyre normal force range (Fz,min, Fz,max) based on the first tyre normal force range (Fz1,min, Fz2,max) and on the second tyre normal force range (Fz2,min, Fz2,max).
