This paper presents the tire testing apparatus estimating for sideslip angle, lateral forces and cornering stiffness of a tire. This project aims to design, fabricate and test an apparatus to obtain tire cornering stiffness using static method as of the title. The test was manually done using the designed apparatus by measuring the weight on wheel with a weighing scale and the forces required to turn the wheel with a hanging scale, done on the tar road. The estimated results from the apparatus were verified by the results taken from the UTP team 2012 vehicle by the Satellite Data Logger DL2 paired with Race Technology V7 software. It was found that there was a difference of 36% on the result collected using the static apparatus compared to the software data. Additionally, this apparatus presents a lower cost alternative to estimate the cornering stiffness of a tire.
