What Hub Centric Rings Do I Need? | Wheel Tech

This is part II, and assumes you know what a hub centric ring is, and why they are important. If you want to start at the beginning check out Part I here: What is a Hub Centric Ring?

Sizing It Up

While it can be intimidating at first, picking the proper hub centric ring for your new setup is quite easy. There are two important numbers you need to know.

  1. Outside Diameter needs to match the center bore of your wheels. Many aftermarket passenger car wheels use a standard size of 73.1mm or 72.56mm. This is larger than just about every car on the road and allows the wheel to be easily made hub centric with the use of a hubcentric rings. If you are unsure what this is, please contact your wheel manufacturer, wheel vendor or use a caliper to carefully measure the hole in the back of the wheel.
  2. Inside Diameter needs to match the hub bore of your vehicle. If unsure contact us, check your vehicle’s owners manual or do a quick google search; something like “1989 BMW 318i hub bore” usually yields good results.

    Hi, I’m in need of buying hub centric rings. I drive a 2004 Chevy Silverado 4.3L sub-model WT 4×2 RWD. I bought a set of American Racing Custom Wheels AR23-6883 model # (16×8″/6×139.7mm, 0mm offset with 6 holes x 5.5inch pitch circle diameter x 0mm item offset x 4.5inch wheel backspacing with bore diameter of 108mm). Please confirm the OD of 108mm and if you can advise what the ID would be for the hub centric rings. Thanks. I purchased a set of CP valve stems on Amazon and there is also a set of hub centric rings CP-SET-HRN-108-78.1 that I believe may fit too?

    I have a 1996 Chevrolet S-10 LS 4×4 that came with American Racing AR23 MA-127L. All I know is they are 15×10 and back spacing is unknown but I need a set of hub centric rings for it. Can you help me with that information given?

      Your truck has a 70.3mm hub bore, so that’s the inside diameter of the hub ring you need. Measure the hole diameter in the back of your wheels to determine the centerbore – that will be the Outside Diameter (OD) of the hub ring you need.
