What is the bolt pattern on a 1979 Ford Ltd?
The 1979 Ford Ltd uses a 5-lug pattern on a 5-inch bolt circle (5x5.0 inches, about 127 mm).
Bolt pattern details
The 1979 LTD, part of Ford’s full-size lineup from that era, commonly used a five-lug wheel hub arranged on a 5-inch circle. This pattern is typically referred to as 5x5.0 in (127 mm). It was standard across many Ford full-size models of the late 1970s, such as the LTD, Crown Victoria, and Grand Marquis families, though exact specs can vary by production run or region. Wheels with a different bolt pattern, like 5x4.5 in, will not bolt on without adapters and may not fit safely.
Why the distinction matters
Wheels must match the bolt circle precisely. Using wheels with an incompatible bolt pattern can damage studs, hubs, and brake components, and can prevent proper seating of the wheel. Always verify the bolt pattern on your specific vehicle before buying wheels or adapters.
How to verify the bolt pattern on your car
To confirm your car’s bolt pattern, measure the distance between two opposite lug studs through the center of the hub to determine the bolt circle diameter. For quick checks, consult the vehicle’s manual, a door jamb or trunk sticker that lists wheel information, or a parts catalog using the VIN. If in doubt, a local tire shop or dealership can measure it accurately.
Additional notes
Although many 1979-era Ford full-size models shared the 5x5.0 in pattern, some regional or trim variations could differ. When upgrading wheels, also consider center bore size and wheel offset, not just the bolt pattern. If you plan to use adapters, be aware of safety, alignment, and warranty implications.
Summary
In short, a 1979 Ford Ltd typically uses a 5-on-5 inches (5x5.0 in) bolt pattern. Verify against your specific vehicle documentation or a wheel professional to ensure accuracy for your exact car and any wheel upgrades.
