Thank you everyone for your input, very helpful indeed. I like these wheels, I can't imagine the car wearing anything else! I measured the width of the rim as 6" when I balanced them so most likely they are a 6J. I am changing the front brake calipers, when they arrive that is, and will check the inside of the rims for any other markings and numbers. That will be a major cleaning job!
Regarding new wheels, I had specified the make, model and year of the car and been told that the correct offset would be applied at the time of ordering. I wasn't sure then about the J part of it but with your help, that is much clearer. Whatever I do, I must make sure they have four holes and not five to mount the wheels on the hubs. This is a whole world I never knew existed! Regarding plastic rings to centre the wheels Hans, mine do not have them at all. The wheels are a nice snug fit when pressed to the hub and hold well as the bolts are put in place. After I balanced the wheels, the wobble at around 60mph had gone. A very useful tip nonetheless and one I will bear in mind if I do change the wheels completely, the companies I looked at all mentioned rings and I wondered what they were for. I would be interested to find out more Robmirach. Apart from the non-matching and missing centre covers, I do not have a good spare either! The boot contains an original XR2 pepperpot wheel with a tyre size that does not match the rest. There is also a honking great nail through the tread that I hadn't notice in the last 15 years. If anyone wants the wheel, you are welcome - nail included! Thanks again. Martin -- -- You received this message because you are subscribed to the Google Groups "Quantum Owners Group" group.
