What is the bolt pattern on a 2003 Chevy S-10 Xtreme?
The bolt pattern is 5 on 4.75 inches (5x4.75" / 120.65 mm).
For the 2003 Chevy S-10 Xtreme, this 5-lug pattern applies to both the two-wheel-drive and four-wheel-drive variants. Wheels with a different bolt pattern won’t mount correctly unless adapters are used, and incorrect fitment can be unsafe.
Bolt pattern basics
The 5x4.75 pattern means five lug studs are arranged on a circle with a diameter of 4.75 inches. This configuration is standard on most GM compact pickups from that era, including the S-10 Xtreme.
Note: Some wheel retailers list the pattern as 5x120.65 mm. When ordering wheels, ensure the listing shows 5x4.75 inches (not a similar but non-matching pattern).
How to verify on your vehicle: you can confirm by checking the factory wheel hub or by measuring the circle formed by the lug holes if you’re unsure.
Wheel compatibility checklist
Before buying wheels for a 2003 S-10 Xtreme, consider these quick checks:
- Bolt pattern: 5x4.75 inches (5x120.65 mm).
- Center bore and offset considerations can affect hub centering and brake clearance. Verify hub bore size and wheel offset for your specific wheels.
- Wheel diameter/width must clear suspension components and brakes without rubbing.
If you’re unsure, consult a parts professional or compare the specification against your vehicle’s VIN and the factory service manual.
Measuring and confirming on your own
If you prefer to verify the bolt pattern yourself, follow these basic steps:
- Find two lug holes directly opposite each other on the wheel and measure the distance between their centers. This is the bolt circle diameter.
- Confirm there are five lug holes arranged evenly around that circle.
- If the measurement is approximately 4.75 inches (120.65 mm) with five equally spaced holes, you have a 5x4.75 pattern.
In practice, most owners rely on the factory specification or confirmations from a trusted parts retailer to ensure accuracy for wheel replacements.
Summary: The 2003 Chevy S-10 Xtreme uses a 5-lug bolt pattern on a 4.75-inch circle (5x4.75"/120.65 mm). Always verify hub bore and offset for any new wheels to ensure proper fitment and safety.
What is a S10 lug pattern?
The S10 bolt pattern varies by generation, but is typically 5x120.65 mm (5×4.755 cross 4.755×4.75 inches) for most models from 1982 up to 2004. Later models, particularly the 2000s Brazilian-built S10s and other international variants, often use a 6x139.7 mm (6×5.56 cross 5.56×5.5 inches) bolt pattern. Always verify the specific bolt pattern for your truck's year and model before purchasing wheels.

What is the 5X120 bolt pattern equal to?
A 5x120 bolt pattern is the metric equivalent of a 5x4.72-inch bolt pattern. While very similar, it is slightly different from the 5x120.7mm (5x4.75-inch) pattern, which is common on some vehicles like older Corvettes and Camaros. The difference is small (only 0.7 mm0.7 mm0.7 mm), but can cause issues if not addressed with proper adapters or hub-centric rings.
Key takeaways
- 5x120 mm is the same as 5x4.72 inches. This is a common bolt pattern for many modern vehicles.
- It is not the same as 5x4.75 inches, though the two are often confused. The difference is about 0.7 mm0.7 mm0.7 mm (0.028 inches).
- For a perfect fit, always match the exact bolt pattern. Trying to fit a 5x4.75 wheel onto a 5x120 hub (or vice-versa) can cause pressure on the studs and lead to damage or safety issues.
- Use proper adapters if needed. If your vehicle has a 5x4.75 bolt pattern and you want to use 5x120 wheels, you can use a wheel adapter. These adapters can help ensure a proper fit and reduce the risk of damage to your vehicle.
- Always check compatibility before buying. Before purchasing wheels for your vehicle, check its specific bolt pattern and compare it to the wheel's specifications. You can also check the manufacturer's website or consult a professional if you are unsure.
What lug pattern is the same as 5x127?
A 5x127 (or 5x5) bolt pattern can be converted to other patterns like 5x114.3 (5x4.5) or 5x139.7 (5x5.5) using wheel adapters or spacers. These parts are bolted to the vehicle's hub, and their design converts the existing bolt pattern to a new one, allowing wheels with a different bolt pattern to be installed. It is critical to ensure the adapter is designed for your specific vehicle and the wheel you intend to use, as well as that it is installed correctly to avoid damage.
How it works
- Wheel adapters and spacers: are custom-made metal plates that bolt onto your existing wheel hubs.
- They feature a different bolt pattern on the other side, which then connects to your new wheels.
- For example, an adapter for a 5x127 to 5x114.3 conversion would have five studs for a 5x127 pattern on the side that mounts to the vehicle, and five holes for a 5x114.3 pattern on the side that the new wheel mounts to.
Common conversions
- 5x127 (5x5) to 5x114.3 (5x4.5): Many modern cars use the 5x127 bolt pattern, and wheel adapters can convert this to the more common 5x114.3 pattern.
- 5x127 (5x5) to 5x139.7 (5x5.5): A popular conversion for older trucks and SUVs that can be converted from 5x127 to a 5x139.7 pattern, notes Amazon.com.
Important considerations
- Select the correct adapter: Make sure you are buying the correct adapter for your vehicle and the wheel you want to use. Double-check the size and specifications before purchasing.
- Proper installation: Always follow the installation instructions carefully. Overtightening lug nuts can cause damage, and it is recommended to torque them to the manufacturer's specifications.
- Hub clearance: Some adapters are thicker than others and may require shortening the factory wheel studs to ensure the wheel sits flush against the adapter. Consult the adapter's specifications to see if this is necessary.
