Tires of modern commercial vehicles must meet a specific requirement profile, containing the economic aspects, ride comfort and driving safety, as well. These three primary criteria are discussed in this paper, whereby emphasis is placed on the force transmission behavior of commercial vehicle tires regarded as a variable directly associated to driving safety. At the same time, the influence of distinct parameters such as wheel load, road speed, tire inflation pressure, tread depth and coefficient of adhesion between tire and road on the lateral and braking force behavior is illustrated using steady state and dynamic measurements. They were carried out on real roads using a specially prepared mobile tire dynamometer, but on an indoor drum-type tire test stand, as well. In addition to the above mentioned parameter variations the differences of the results on account of the test method are analysed.
