195/45 R16 tyres are installed in family cars and executive cars. The size of the tyre can be seen on its side. It is presented in a clear way in the above form. The first number informs about the tread width of the tyre and it is provided in millimetres. In the case of the 195/45 R16 tyre it is 195 mm. The second number equals the tyre profile's height and its percentage ratio to the tyre's tread width (here 45% out of 195 mm). The "R" in the tyre's size denotes its radial construction. The last number (16 here) constitutes the diameter of the wheel rim (provided in inches) on which the tyre should be installed. See the 195/45 R16 tyre model in our broad catalogue of products.
