XXR Wheels Center Cap Buying Guide

XXR Wheels are a staple of the sport compact and import tuner scene, known for their lightweight construction, aggressive fitment, and wide range of finish options. Their center caps are snap-in style and come in multiple colors to match the brand's diverse wheel finishes. Here's how to find the right replacement cap for your XXR wheels.

XXR Cap Part Numbers & Finishes

XXR caps use a consistent part number — 31XR85 — across multiple finish variants. The finish is the primary differentiator:

  • 31XR85 (Silver) — Silver finish, suits XXR wheels in silver, hyper silver, or polished finishes.
  • 31XR85 (Gray) — Gray finish, a popular choice for matte or satin gray wheel builds.
  • 31XR85 (Chromium Black) — Dark chrome finish, suits black chrome or dark tinted wheel builds.
  • 31XR85 (Gloss Black) — Gloss black finish, the most versatile option for blacked-out or two-tone builds.

Pro tip: Because XXR uses the same base part number (31XR85) across all finishes, the finish color is the only thing you need to specify when ordering. Match it to your wheel's finish for a seamless look.

How to Find the Right XXR Cap

  1. Identify your XXR wheel finish — XXR offers wheels in silver, hyper silver, gloss black, chromium black, bronze, and more. Match the cap finish to your wheel finish.
  2. Verify the bore size — XXR caps use an 85mm bore (encoded in the "85" in part number 31XR85). Measure your center bore to confirm.
  3. Snap-in retention — All XXR caps use a snap-in design. Check that the retention ring groove in your wheel bore is intact before ordering.

XXR Wheel Fitment & Cap Compatibility

XXR wheels are popular for aggressive fitment builds — wide wheels, low offsets, and stretched tires. The center cap sits in the center bore regardless of offset or width, so fitment of the cap itself is straightforward as long as the bore size (85mm) matches. If you've changed wheels but stayed within the XXR lineup, the same 31XR85 cap likely fits.
