This brings to cover greater stability and resistance; the diagonals, the layers are sunsets just diagonally one over the other; and in the self-supporting layers are also on each other in straight and on the flanks. This gives strength to cover although it remains in the area of comfort since it makes it more rigid. The most usual is its application in sports cars.
A physical characteristic of the tires is that they is registered its dimension, for example, if registered the following legend 225/50R16 91W, this will be read in the following way: the first number corresponds to the sectional width from the edge of one band to the other; the second issue involves the height of the profile; the R gives an account of its radial type; the next number is the measure of the interior circumference; the fourth number indicates the load that must be given to the tyre; and the final letter will mean the speed that can be achieved. Code W refers a speed up to 270 Km/H.
