When upgrading or replacing the wheels on your Chevrolet S10, knowing the bolt pattern for S10 is crucial. The bolt pattern determines which wheels will properly fit your truck, ensuring safety, performance, and aesthetics. In this detailed guide, we will explain what a bolt pattern is, the exact bolt pattern , compatibility with other vehicles, and tips for choosing the best wheels.
What is a Bolt Pattern?
Before we dive into the bolt pattern for S10, let’s understand what a bolt pattern is. A bolt pattern (also called a lug pattern or PCD – Pitch Circle Diameter) refers to the arrangement of lug holes on a wheel. It is represented as:
- Number of lug holes – The number of bolts that secure the wheel to the hub.
- Diameter of the circle – The distance across an imaginary circle that passes through the center of each lug hole.
For example, if a bolt pattern is 5×4.75, it means the wheel has 5 lug holes arranged in a 4.75-inch diameter circle.
Bolt Pattern for S10
The Chevrolet S10 has different bolt patterns depending on the year and model. The most common bolt pattern for S10 is 5×4.75 inches (5×120.65 mm). This means it has 5 lug holes arranged in a 4.75-inch diameter circle.
Chevy S10 Bolt Pattern by Year
| Year Range | Bolt Pattern | Center Bore | Lug Nut Size |
|---|---|---|---|
| 1982-2004 | 5×4.75 (5×120.65mm) | 70.3mm | M12x1.5 |
All Chevrolet S10 models use a 5-lug pattern with a 4.75-inch (120.65mm) spacing. This pattern remains consistent across the years, making it easier to find compatible aftermarket wheels.
Understanding Wheel Specifications
Aside from the bolt pattern for S10, you should consider other important wheel specifications:
1. Center Bore
The center bore is the hole in the middle of the wheel that fits onto the hub. The Chevrolet S10 has a center bore of 70.3mm. When purchasing aftermarket wheels, make sure the center bore matches or is larger (in which case, hub-centric rings can be used).
2. Lug Nut Size and Torque
The S10 uses M12x1.5 lug nuts, and the recommended torque is 100 ft-lbs to ensure the wheels are properly secured.
3. Wheel Offset
Offset refers to how far the mounting surface is from the centerline of the wheel. The S10 typically has a low to medium offset, meaning the wheels do not stick out too far from the fenders.
Compatible Vehicles with the S10 Bolt Pattern
If you’re looking for wheels that fit the bolt pattern for S10, here are some vehicles that share the 5×4.75 bolt pattern:
- Chevrolet Camaro (1967-2002)
- Chevrolet Malibu (1978-1988)
- Chevrolet Monte Carlo (1978-1988)
- Chevrolet Corvette (1955-1982)
- Pontiac Firebird (1967-2002)
- Buick Regal (1978-1987)
This means you can swap wheels between these models as long as the offset and center bore are compatible.
Choosing the Right Wheels for Your S10
When selecting new wheels, consider these factors:
1. Wheel Material
- Steel Wheels – Durable and budget-friendly, ideal for heavy-duty use.
- Alloy Wheels – Lightweight and stylish, offering better performance and fuel efficiency.
2. Tire Size Compatibility
Ensure that the tires you choose are compatible with your S10’s suspension and wheel wells. Popular sizes for the S10 include 235/75R15 and 225/70R15.
3. Aesthetic Appeal
Choose a wheel design that enhances the look of your truck while maintaining functionality. Popular choices include:

- Deep-dish rims for a custom look
- Off-road wheels for enhanced durability
How to Measure Bolt Pattern for S10
If you want to verify the bolt pattern for S10, follow these steps:
- Count the Lug Holes – The S10 has 5 lugs.
- Measure the Diameter – Since it has an odd number of lugs, measure from the center of one lug hole to the back edge of the opposite lug hole.
- Confirm the Size – You should get 4.75 inches (120.65mm).
Can You Change the Bolt Pattern on an S10?
Yes, it is possible to change the bolt pattern using wheel adapters. Wheel adapters allow you to fit wheels with a different bolt pattern onto your truck. However, keep in mind:
- They must be high-quality to ensure safety.
- They increase track width, which may affect handling.
- They require proper installation to prevent wheel wobble.

When selecting wheels, consider factors like center bore, lug nut size, and offset to ensure a perfect fit. Whether you’re looking for performance wheels or custom designs, understanding your truck’s bolt pattern helps you make the right choice for safety and style.
