They refer to wheels, not tyres.

PCD is basically the stud pattern. For example, old french cars are usually 4x100, classic Imprezas are 5x100 etc etc

ET is the offset, and again, in simpleton terms is the distance between the absolute centre of the wheel and the mounting face (that bolts to the hub). The lower the offset, the more the wheel will 'stick out' of the arch. The higher the offset, the further in the wheel will sit.
