195/50 R15 tyres are produced with family cars in mind. The size of the tyre can be seen on its sidewall along with other labels. The "R" in the tyre's size denotes its radial construction). The first number informs about the tread width of the tyre and it is provided in millimetres. In this case it is 195 mm. The height of the 195/50 R15 tyre is designated by the second number (it is a percentage ratio to the tyre's tread width, here 50% out of 195 mm). The third number provides in inches the diameter of the wheel rim on which the tyre should be installed. See the 195/50 R15 tyre model in our broad selection.
