165/40 R16 tyres are produced with executive cars and family cars in mind. The size of the tyre can be seen on its side. It is presented with the help of strings of numbers and letters. The first number informs about the tread width the 165/40 R16 tyre. The number is provided in millimetres and in this case it is 165 millimetres. The second number equals the tyre profile's height and its percentage ratio to the tyre's tread width (40% out of 165 mm) The "R" in the tyre's size denotes its radial construction while the number 15 (in inches) is the diameter of the wheel rim on which the 165x40 R16 tyre should be installed.
