VEHICLE-IN-USE LIMIT PERFORMANCE AND TIRE FACTORS. THE TIRE IN USE. APPENDIX A,B,C
The influence of tire-in-use factors (inflation pressure, replacement mixes, and wear) on the steering and braking response of automobiles is examined through analysis, simulation, laboratory and over-the-road tire testing, and vehicle testing. Results for a 1971 Mustang and a 1973 Buick station wagon illustrate the influence of tire-in-use factors on (a) the open-loop braking and/or turning performance in drastic maneuvers on wet and dry surfaces, and (b) the understeer/oversteer factor for maneuvers involving lateral accelerations below 0.3 g. The investigation shows that differences in tire mechanical properties between the front and rear wheels (as caused by tire-in-use factors) can cause significant and potentially dangerous changes in limit response and from the stability and control characteristics intended by the vehicle manufacturer.
