The Chevrolet S10 is a popular compact pickup truck that has been in production for several years. One of the key aspects of maintaining or upgrading your S10 is understanding the Chevrolet S10 wheel bolt pattern. This specification is crucial for ensuring that your wheels fit properly, maintaining safety, and optimizing performance. In this guide, we will cover everything you need to know about the chevrolet s10 wheel bolt pattern, including how to measure it, compatibility, and wheel selection.
What Is a Wheel Bolt Pattern?
A wheel bolt pattern consists of two numbers: the first represents the number of lug holes, while the second indicates the diameter of the circle that passes through the center of these holes. For the Chevrolet S10, the most common wheel bolt pattern is 5×120.65mm (5×4.75 inches). This means the wheel has five lug holes arranged in a circle with a diameter of 120.65mm (4.75 inches).

Depending on the model year, the Chevrolet S10 may have different bolt patterns. Below are the most common configurations:
- 1982-2004 Chevrolet S10: 5×120.65mm (5×4.75 inches)
- Chevrolet S10 ZR2 Models: 6×139.7mm (6×5.5 inches)
The regular S10 models use a 5-lug pattern, while the off-road-focused ZR2 version features a 6-lug pattern for added durability and strength.
How to Measure the Chevrolet S10 Wheel Bolt Pattern
If you need to confirm the Chevrolet S10 wheel bolt pattern, follow these steps:
- Count the Lug Holes: Identify whether your wheel has five or six lug holes.
- Measure the Diameter: If your truck has five lug holes, measure from the center of one lug to the outer edge of the lug directly across. This should be 120.65mm (4.75 inches).
- Use a Bolt Pattern Gauge: For an accurate reading, use a specialized bolt pattern gauge.
Why Is the Chevrolet S10 Wheel Bolt Pattern Important?
Understanding the Chevrolet S10 wheel bolt pattern is important for multiple reasons:
