The paper analyses tire vibration caused by Road Force Variation on passenger car tires and presents suggestions for reducing tire vibration. Considering multiple samples, we are analyzing Radial Road Force Variation and practical solutions for best reduction of loaded radial run-out of the tire and rim assembly. Tire vibration resulting from Road Force Variation can be greatly influenced by the way that the tire is installed on the rim. This study is a part of a larger project presenting Contributions to the Study of Surface Vehicle Vibrations by analyzing Tire - Car system aiming to reduce fuel consumption and non-biodegradable waste.
