Hubcaps 

"The Correct Way to Measure Wheel and Rim Size..."

When you measure for rim or hubcap size don't use a tape measure.  If you do you will be wrong every time. The tape mueasure will measure over an inch larger than the actual wheel size.

Did you know that rim size is determined by the diameter of the BEAD of the TIRE?  You can't measure that without taking the tire off the wheel.

"Size Series"

Most people don't under stand the "Size Series" code printed on the side wall of a tire.  That code indicates the wheel and rim size. YOu will notice that code usually begins with a "P" for Passenger vehicle or "LT" for Light Truck.

The codes look like this:   P185/70/R16.       LT225/80/R16.

The two digit number following the "R: indicates the rim or wheel size is 16 inches.  The letter "R" simply means it is a Radial tire.

Hubcaps or Wheel Covers, What's in a Name?...
By Phil Sollecito

 

Hub Caps - Cars and trucks built before about 1935 came on wire spoke wheels with small metal caps installed to seal the wheel hub on the axle. Those early "HUBcaps" were smaller than 3" in diameter, made of heavy gauge plated steel hammered onto the hub of the wheel. Their main function was to keep dirt out of the spindle nut and wheel bearings.

Stamped Steel Wheels

In the mid ‘30s, hubcaps became more decorative than functional. The ‘dog dish’ style was born, chrome hemispheres 9 inches in diameter, covering the lug nuts and the center of the wheel. About the same time, wheel technology advanced and spoke wheels were replaced by wheels formed from stamped steel.

In the ‘40s, Cadillac lead the pack in adding sparkling chrome by the acre: bumpers, grills, trim lines, window borders, hood ornaments, hood vents, headlights, running boards, etc. Increasing the size of the chrome hubcaps added reflective surface.

By the ‘50s, hubcap diameters increased to the point they covered the entire steel wheel. Many of this period were flat chrome rounds looking like Frisbees, with little differentiation. During this time the term ‘wheel cover’ came into use.

Over the last 50 years, the terms ‘hubcaps’ and ‘wheel covers’ have become synonymous as the lightweight, full-diameter decorative coverings of standard steel wheels.

Interchangeablility

One of the hallmarks of modern hubcaps is their interchangeability. Nearly any hubcap of the correct size will fit any standard steel wheel that will take a hubcap. This means that changing styles is very easy. We are not limited to those styles designed by our particular auto manufacturer.

What's a "Wheelskin"?

Wheelskins were introduced as an inexpensive way to put bright chromed plastic covers on styled wheels. Precision molds were designed to manufacture inexpensive, corrosion resistant covers that perfectly match the shape of styled wheels.  That's where the name comes from.  They ‘fit like a glove’ as tight as a second "skin".

Impostors and Wheelskins are the two most popular manufacturers. There is no room for error when buying these puppies, because only one model of Wheelskin will matche each specific styled wheel.
