What is the bolt pattern on a Chevrolet pick up?

Most Chevrolet pickups use a 6x139.7 mm bolt pattern on light-duty models, while the heavy-duty Silverado 2500HD/3500HD uses an 8x165.1 mm pattern. Always verify for your exact year and trim.

Bolt pattern (lug pattern) refers to the number of wheel studs and the circle they form on the wheel hub. This matters when selecting wheels, spacers, or adapters, and it can vary by model family and generation. The guide below covers the patterns you’ll encounter on current Chevrolet pickups and how to verify them accurately.

Bolt patterns by Chevrolet pickup family

Before buying wheels or adapters, confirm the exact pattern for your vehicle using its VIN, owner's manual, or the hub spec. These patterns reflect mainstream configurations for Chevrolet pickups in recent years.

• Light‑duty pickups and related midsize offerings: 6x139.7 mm (6 on 5.5 inches).


• Heavy‑duty pickups (Silverado 2500HD/3500HD): 8x165.1 mm (8 on 6.5 inches).

In short, current light-duty Chevrolets (like the Silverado 1500) and typical midsize Chevrolets (such as the Colorado/Canyon in recent generations) use 6x139.7 mm. The heavy-duty Silverado 2500HD/3500HD uses 8x165.1 mm. Always verify your exact year, model, and trim to be certain, as there can be exceptions.

How to verify your exact bolt pattern

To ensure you get the correct wheels or spacers, check the vehicle’s documentation or measure the bolt circle yourself if you have the proper tools. The steps below guide most owners through a simple verification process.

1. Consult the owner's manual or a Chevrolet dealership for the precise lug pattern for your exact year and model.


2. Inspect the wheel hub for stamped information indicating the bolt pattern or measure the distance between lug studs with a caliper.


3. If needed, count the lug studs and measure the center-to-center distance across opposite studs to confirm the bolt circle (e.g., 6x139.7 mm or 8x165.1 mm).

Verifying the bolt pattern protects against incorrect wheel purchases and ensures proper fitment and safety.

Summary

For Chevrolet pickups today, the standard patterns are 6x139.7 mm for light-duty Silverado 1500s and most midsize Chevrolets, and 8x165.1 mm for heavy-duty Silverado 2500HD/3500HD variants. Always confirm the exact specification for your year and model to avoid mismatches when sourcing wheels or adapters.

What is the five lug Chevy Bolt pattern?

Chevy uses several 5-lug bolt patterns, with the most common being 5 on 4.75 inches (also known as 5x120.65mm) for many older cars and trucks, and 5 on 4.5 inches (also known as 5x114.3mm) for some specific models. To find the correct pattern for your vehicle, identify the size of your vehicle's bolt pattern, which will be listed in one of these formats.
 
Common Chevy 5-lug bolt patterns

• 5 on 4.75 inches: A very common pattern for many older Chevy vehicles, including some Caprice models and the 1995 Chevy 1500. 
• 5 on 4.5 inches: Used on some Chevrolet models and easily identifiable by the 4.5-inch measurement. This pattern is also shared with many other domestic and import cars. 
• 5 on 5.0 inches: This pattern is typically found on larger Chevy trucks and SUVs, and is metrically equivalent to 5x127mm. 
• 5 on 105mm: This metric pattern is used on smaller, more modern vehicles like the Chevrolet Aveo, Cruze, and Sonic. 

How to measure a 5-lug pattern

1. Get a tape measure.
2. Measure from the outside edge of one lug to the center of the lug directly across from it, skipping one lug. 
3. The resulting measurement is the bolt pattern. 

Important considerations

• When ordering new wheels, use the metric equivalent if available, as most manufacturers list their bolt patterns in millimeters. 
• For 5-lug patterns, the correct measurement technique is crucial. Measuring from the center of one stud to the center of another stud is not the accurate way to determine the pattern. 
• Always double-check your vehicle's specific bolt pattern before ordering new wheels.
