So called „Roughness Index“ (RI) is a relative number which enables the user to compare the tread patterns. The higher is the value of the index the rougher is the pattern no matter the size of the tyre. This scale corresponds to the right usage of each pattern for each type of terrain starting from a smooth asphalt road up to broken heavy stony or muddy terrain. Even though the complete characteristics must be more detailed yet this system gives a fast, simple and effective orientation in the pattern assortment.
