ABSTRACT TIRE BACKROUND
The purpose of this document is to describe important While the wheel may have been one of man’s first
tire characteristics and their effect on vehicle inventions, the rubber tire is definitely not one of the
performance. Characteristics considered are those that simplest components to analyze. The rubber tire is a
the Formula SAE judges have deemed important for complex composite consisting mainly of vulcanized
discussion on tires at competition and include coefficient rubber, which more specifically is an elastomer with a
of friction, slip angle, slip ratio, camber angle, cornering high number of sulfur cross-links between the polymer
stiffness, camber stiffness, self-aligning torque, normal chains. The composite also contains carbon black, oil
load sensitivity, load transfer sensitivity and pneumatic extenders and layered reinforcing strands or fabrics
trail. Every effort has been made to list sample values to called plies. These strand
