Tyres in size 255/30 R21 are designed for cars of a sports character. The first number (255) in the size denotes tyre's tread width expressed in millimetres. The next number is a designation of the tyre's profile height in percentage (it amounts 30% of 255 millimetres of the tyre's tread width). After these two numbers, there is the "R" that means that the tyre has been produced according to the radial construction. The number next to it is a designation of the diameter of the wheel's rim (in inches) on which the tyre in size 255/30 R21 can be installed.
