The tire is the most consumable element in any vehicle. The geometry of the road wheels most often has an impact on this state of affairs. Incorrect geometry causes not only accelerated tire wear and increased fuel consumption, but also poor vehicle handling, which affects driving safety. A typical symptom of bad geometry is the "pulling" of the vehicle. Similar problems occur in truck tractors with a semi-trailer. If one of the axles of the semi-trailer is crooked and the driver takes his foot off the gas pedal, the semi-trailer will push the tractor. The driver may get the impression that the "pulling" is due to incorrectly set geometry of the tractor. During our visits to workshops, we often encounter problems as above
