What is the bolt pattern on a 1955 Chevy truck?
The bolt pattern for most 1955 Chevrolet pickups is a 5-lug setup on a 4.75-inch circle (5x4.75 inches). This means five studs arranged on a circle with a diameter of 4.75 inches, the standard GM pattern of the era.
In context, the 1955 model year introduced Chevrolet’s Advance-Design trucks, and the lug arrangement aligned with other GM light trucks of that period. Restorers and parts catalogs consistently reference 5x4.75 for these trucks, a detail that matters when sourcing wheels, hubs, drums, and related components.

For anyone restoring or maintaining a 1955 Chevy truck, this 5x4.75 pattern is the most common reference point. Confirming the exact pattern on your axle or hub is still wise, since variations can occur by model or trim in some early GM trucks.
Notes for wheel swaps and upgrades
When sourcing wheels or considering changes, verify not only the bolt pattern but also center bore size, lug nut type, and thread pitch. If using adapters or spacers, ensure proper installation and safety considerations, as changes to hub centering and lug engagement can affect wheel alignment and braking performance.
Summary
For a 1955 Chevy truck, the standard bolt pattern is 5 on 4.75 inches. This is the most commonly cited configuration for GM light trucks of that era and remains the key detail when sourcing compatible wheels and hubs for restoration or maintenance. Always double-check against your specific axle or parts catalog to account for any model-era nuances.
Is 5x120 bolt pattern the same as 5X4 75?
No, a 5x120 bolt pattern is not the same as a 5x4.75 bolt pattern, but they are very close and can sometimes be used interchangeably, though it is not recommended for safety reasons. The 5x120 pattern is metric, while the 5x4.75 pattern is in inches and is equivalent to 5x120.65 mm. This slight difference of about 0.650.650.65 mm can cause stress on the wheel studs.

Why they are not the same
- Size difference: The 0.650.650.65 mm difference, while small, is not the same. A 5x1205 x 1205𝑥120 wheel will not sit perfectly flush on a 5x4.755 x 4.755𝑥4.75 hub, or vice versa.
- Safety risk: The slight mismatch can cause the wheel studs to be under stress, and the wheel may not be as secure as it should be.
- Lug nut bevel: The lug nut bevels may not match perfectly between the two patterns, further increasing stress.
When you might consider using them interchangeably
- "Close enough" applications: Some people do use them interchangeably, especially on older vehicles, because the size difference is so small.
- Use with caution: If you do choose to interchange them, be aware of the potential safety risks. Using wheel adapters is a safer way to ensure a proper fit if the bolt patterns don't match.
