size you need should be same as xB (54mm-73.1) But you should be able to get at any tire and wheel shop, I just ordered mine from ebay because they Shipped with my wheels I won from same company,I read on here that one guy bought his at Discount Tire, Hope this helps Good luck , and I asked the same Question a while back and was told to Run them

 

the way the wheels was made is what determines wether you need hubcentric rings or not. Most alloy wheels DO need them. Steel wheels don't need them because of how they are built.

 

If you torque your wheels down correctly, you won't need them. I've had 2 sets of wheels that weren't hubcentric and I've had no vibrations or anything. Ideally, you'd buy wheels that fit our hub perfectly (54.1mm), but they can be hard to find since most aftermarket wheels usually make them larger to accomodate for more cars. I suppose since HCRs are so cheap, it couldn't hurt though. Just bring the wheels into any tire shop and they can help you find the right size.

 

They should come with your wheels, most wheel companies will include a set og "Hub Rings" at no charge with a purchase of 4 new wheels.
