Fitting Hubcaps or Trim Rings to Steel Wheels
Or: How to tell if your (Not-Quite-Standard) wheel may fit
Proper fit of Hubcaps or Trim Rings to modern Standard Steel Wheels is easy.
With very rare
exceptions, all of our Universal Fit models will work. Steel wheels
manufactured prior to 1974 may or may not have been to the specifications
adopted as standard subsequent to 1974.
All alloy wheels are NOT standard and will NOT take standard Hubcaps or Trim Rings.
Though lighter, alloy wheels are molded of thicker metal which therefore cannot
meet standard measurement specifications for steel wheels. If you have Styled Steel or Alloy
Wheels, there may be
Wheelskins to fit your wheels.
Some steel wheels are "near standard" specification and might or might not take a hubcap or trim ring. This page is meant to help you to determine whether your wheels will take standard wheel treatments.
First Let's see whether your wheels will take hubcaps, or are they one of the rare ODD ones.
There is some variation in the cross-section of different steel wheels. Probably over 99% of steel wheels are "standard" enough that they will take any of our universal-fit hubcaps. In rare instances, less than 10 per year out of the many thousands of hubcaps we sell, customers report that their wheels will not take our universal fit hubcaps.
Now Let's talk about how hubcaps fit into the recess around the bead area of the wheel.
pictures below show tangential views of the edges of hubcaps and trim rings,
with a ruler positioned to show how deep the mounting struts, legs, or clips
project into the recess around the bead of the wheel.
As the pictures show, if you place a straight edge across the rim of the steel wheel, the mounting struts project 1.7 to 1.8 inch into the recess around the bead of the tire, where the valve stem emerges. If the depth of the recess is any less than this, the struts or clips will bottom out and the hubcap will not be able to mount tightly to the rim, making it likely to fall off. Also note that the curvature at the bottom of the recess may be "different" on some wheels, such that it curves toward the wheel center more steeply, and this factor may also make fitting problematic.

2. Hubcap or trim ring measured diameter is generally 1.4 inch larger than the wheel size read off the tire.
The pictures below show how to measure the depth of the recess around the bead area of the steel wheel with a straight-edge and a ruler. Position a straight-edge so it touches the edge of the rim in two places and measure in to the Middle of the Base of the Valve Stem. If this is 1-3/4 inch or deeper, standard hubcaps/wheel covers and trim rings will fit.
