The activity presented in this paper is placed in a broader context of a collaboration between FCA Italy and the Università di Pisa on the characterization of the longitudinal tire’s behavior.
Stopping distance measurements are affected by a large quantity of noise factors that contribute to make them not comparable one of the most importants is the road surface temperature during tests.
In particular this paper will focus on evaluating the effect of the solely road surface temperature on the value of measured stopping distances.
In this paper conclusion of six months experimentation and measurement on five different summer tires and one all season are reported.
From data analysis, a corrective formula for stopping distance measurement with road surface temperature is proposed.
This formula is compared to the other ones present in literature and will be validated for future use.
