A tire longitudinal stiffness estimation system includes an electronic communication system disposed on a vehicle. A sensor is disposed on the vehicle in communication with the electronic communication system, and a processor is accessible through the electronic communication system. A sensor measures a parameter associated with the vehicle and communicates data of the parameter to the processor. A mu slip curve generator receives the parameters to generate a mu slip curve in real time from the data. An extraction module extracts raw data from the linear portion of the mu slip curve. A de-noising module de-noising the raw data from the mu slip curve by determining a vector of the raw data, an orientation of the vector, and an orientation of the vector. A de-noising module generates de-noised data, and a stiffness calculator receives the de-noised data and generates a longitudinal stiffness estimate for the tire.
