The History of Magnum 500 Wheels

The History of Magnum 500 Wheels

The Magnum 500 is one of the most recognizable American muscle car wheels ever made. Its five-spoke design appeared on everything from Mustangs to Chargers, and its story is a window into the wheel industry of the 1960s and 70s.

The Origin

The Magnum 500 was manufactured by Motor Wheel Corporation (later Kelsey-Hayes) starting in the mid-1960s. It was designed as a styled steel wheel — a way to give cars a sporty, custom look without the cost of true alloy wheels.

The Design

The wheel has five spokes radiating from the center to the rim. The spokes are part of the steel disc that is welded to the steel barrel. The face is chrome-plated, giving the wheel its signature mirror shine.

What made the design work was the contrast: dark painted or argent accents between the chrome spokes, giving depth and a performance look that plain painted wheels lacked.

Who Ran Them

The Magnum 500 was an OEM option on some of the most iconic American cars:

• Ford Mustang — 1965-1973, one of the most popular applications
• Ford Fairlane and Torino — full-size performance models
• Mercury Cougar and Cyclone — Mercury's performance lineup
• Dodge Charger and Coronet — Mopar B-bodies
• Plymouth Road Runner and GTX — performance Mopars

The wheel was typically a 14x6 or 14x7 — sizes that look small today but were standard performance sizes in the era.

Why They Were Popular

Affordability

The Magnum 500 was a styled steel wheel — cheaper to produce than a cast alloy wheel. It was a popular option package, not a high-dollar upgrade. A buyer could check a box and get the look of a custom wheel at a fraction of the cost.

Durability

Steel wheels are nearly indestructible. They bend rather than crack. For a performance car that was driven hard (and sometimes raced), steel was practical.

The Look

The five-spoke chrome design was striking in the era of plain painted wheels. It was the closest thing to a custom wheel that a buyer could get from the factory.

The Decline

By the late 1970s, the Magnum 500 fell out of favor for two reasons:

1. Aluminum Wheels Arrived

Cast aluminum wheels became affordable in the 1970s. They were lighter, could be made in larger sizes, and offered more design freedom. The steel Magnum 500 could not compete on weight or design flexibility.

2. Performance Cars Changed

The muscle car era ended in the early 1970s with emissions regulations and the oil crisis. The market for performance-styled wheels shrank, and the Magnum 500's customer base disappeared.

The Collector Market Today

Original Magnum 500s in good condition are valuable — especially complete, dated sets with original center caps. A set of four correct, restored wheels for a 1969 Mustang can sell for $600-1200.

Reproductions

Multiple manufacturers produce reproduction Magnum 500s in larger sizes (15, 16, and 17 inch) for restomod builds. These reproductions look correct but are not concours-correct for a numbers-matching restoration.

Identification

• Date codes — original wheels have date stamps on the back. Match the date to the car's build date.
• Part numbers — Kelsey-Hyes stamped part numbers on the wheel. Match to the car's build sheet.
• Center caps — original caps carry the Ford or Mopar logo. Reproduction caps often lack the fine detail.

The Takeaway

The Magnum 500 is a piece of American automotive history — a styled steel wheel that defined the muscle car era. Its chrome five-spoke design is instantly recognizable, and original sets are collector's items. For a period-correct muscle car build, they are the wheel — and they are still being reproduced for owners who want the look in a modern size.
