In recent years, supersingle tires have been introduced in order to replace dual tires. In some countries such replacement is not a straight forward issue due to either lack of knowledge on its mechanical behavior or because their regulations do not consider such tire configuration. Usually, it is assumed that the force transmitted by dual single tires onto the roadway surface is evenly distributed and the contact pressure is quite similar to the tire's inflation pressure, although studies in this topic have shown that these assumptions are not realistic. Therefore, damage produced by supersingle tires is a main concern for road and transportation authorities. In order to obtain information on supersingle tires' behavior, a lab experimental assessment was carried out.
