PCD stands for (pitch circle diameter), this is the diameter of a circle drawn through the center of your wheel's bolt holes. PCD is measured in millimetres and also indicates the number of studs or bolts the wheel will have. The most common fitment has 4 studs with a PCD of 100mm, hence the fitment 4x100.

100 to 112 are readily available :happy2:

Will the 5x112 not fit then?

PQ34 cars i.e. Mk4, 1st TT et al all have a PCD of 5x100

PQ35 cars i.e. Mk5, 2nd TT et al have a PCD of 5x112

As above you can get adapters to fit, but be careful of ET I think even the narrowest adapters are about 1 inch thick i.e. like running 25mm spacers
