What is the bolt pattern on a 1982 s10?
The bolt pattern is five lug holes on a 4.75-inch circle, i.e., 5x4.75 inches (about 120.65 mm).
In practical terms, this means that the 1982 Chevrolet S-10 pickup uses a 5-lug mounting pattern with a 4.75-inch bolt circle. This pattern is standard for this model year and is a key factor when sourcing wheels, adapters, or hub-centric rings. Verifying this pattern helps ensure proper fitment and safe driving.
Bolt pattern basics
The bolt pattern identifies how many lug holes a wheel hub has and the diameter of the circle that passes through the centers of those holes. For the 1982 S-10, the expected configuration is five lug holes arranged around a 4.75-inch circle (also listed as 5x4.75 inches or 120.65 mm).
1982 S-10 specifics
To confirm your exact truck’s mounting pattern, you can measure directly or consult documentation for your specific VIN. The widely accepted standard for this model year is 5x4.75 inches.
To verify the bolt pattern on your vehicle, follow these steps:
- Count the lug holes to confirm there are five.
- Measure the bolt circle diameter (BCD) by measuring from the center of one lug hole to the center of the lug hole opposite it; you should obtain approximately 4.75 inches (120.65 mm).
- If possible, compare with a known 5x4.75" wheel or use a pattern gauge for confirmation.
- Check the hub bore size: many GM S-series trucks use a center bore around 64.1 mm; ensure the wheel’s center bore matches or use hub-centric rings if needed.
Concluding: With the 5x4.75" bolt pattern, wheels and adapters must be compatible with that configuration. Don’t neglect center bore and offset, as mismatches can cause fitment and performance issues.
Additional fitment considerations
Beyond the bolt pattern, wheel compatibility depends on center bore, hub-centricity, offset, and overall wheel width. If a wheel is offered only in a different pattern (for example, 5x5.0" or 5x4.5"), you may need adapters or choose a different wheel. Always verify both the lug pattern and hub bore to ensure proper seating and alignment.
Summary
The 1982 S-10 uses a 5-lug, 4.75-inch bolt pattern (5x4.75" or 120.65 mm). Use this as the baseline when selecting wheels, and also verify center bore and offset to guarantee proper fitment on your truck.
