R - This indicates what the tyre's construction is. R stands for radial which all tyres must be in the present day.

18 - Indicates what the diameter of the inner rim is in inches.

W - This is the speed rating. The symbol indicates the max speed for the tyre at full load (more on speed rating below).

From time to time you may even see a tyre size code that has the speed rating symbol at the finish of the line. For the above tyre example it would look like this: 225/40 R 18 88 W.
