A follow up to my previous thread, 'Alloy wheel nut hex - what size is it meant to be? i.e. what size socket should suit' < Alloy wheel nut hex - what size is it meant to be? i.e. what size socket should suit >.

What is the correct wheel nuts for the spare wheel? Matching ones to the road wheels?

I ask as the D2 had different wheel nuts for the spare than the road wheels - there was an identifying bump or indent to tell which was which.

At present the vehicle has two different styles which don't match, one is longer and has an o-ring on it. Neither has the shiny metal cap.
