I have a 2010 XK. Looking at some new wheels. My hub bore is 63.3 mm. The wheels I want have a center bore of 73.1 mm. I will not need to space them out. Is there such thing as a hub bore adapter?

 

OK, I found a place that makes hub bore adapters to your specific car and wheel hub bore. The new wheels have a 35 mm offset in the front and my originals should be 49 mm from what I have seen here so that would space my wheels out 14 mm which should look great. The back wheels are 40 mm offset at 10" wide and the originals are 46 mm at 9.5 wide so that should set the new wheels right at the originals as far as location outboard. I will add a 15 mm spacer there. That will put all 4 wheels spaced out 14/15 mm.
I will measure the actual offset of the wheels this morning to verify the offsets numbers that I have seen on this forum for a 2010 XK.

 

Took the front and rear wheels off and verified the 49 mm front and 46 mm rear offsets. These are Kalimnos.

 

Hi there Doug,
you're asking about hub adapters and also wheel spacers by the sound of it?

Re the hub bore size differential of 63.3mm to 73.1mm
These are pretty standard and are called spigot rings, they can be bought fairly readily from Ebay and the like.

I had a similar scenario when I changed the wheels on my Audi going from 57.1mm to around 66.7mm iirc, been on the car for several years with no issues.

Wheel spacers you discuss....Please make sure to buy Hubcentric wheel spacers only as the plain washer type that are not hubcentric are very dangerous.
