245/75 R15 tyres are designed for off-road cars. In order to read the tyre's size you only need to search for correct sequence of numbers on its side. The tread width of the 245/75 R15 tyre is provided in millimetres by the first of those numbers (here the tread is 245 mm wide). The second number equals the percentage ratio between the tyre's height and its tread width. In this case it is 75% out of 245 mm. The "R" in the tyre's size denotes its radial construction. The number 15 constitutes the diameter of the wheel rim (provided in inches) on which the tyre should be installed. See our broad selection of the 245/75 R15 tyre model in our offer.
