Silverado Wheel Bolt Pattern Chart by Year and Model 1999–2026
The Silverado wheel bolt pattern chart is straightforward for the 1500, but Chevrolet HD trucks need closer attention. Silverado 1500 models use a 6×139.7 mm pattern, while 2500HD and 3500HD trucks use different eight-lug patterns depending on year and rear-wheel configuration.
The biggest breakpoint is the 2011 model year. Silverado 2500HD and 3500HD single-rear-wheel trucks moved away from the older 8×165.1 mm pattern, while modern 3500HD dually trucks use an even larger 8×210 mm pattern.

Silverado Wheel Bolt Pattern Chart for 1999 to 2026
The fastest way to identify the correct Silverado wheel pattern is to match the model, model year, and rear-wheel configuration.
| Silverado Model | Model Years | Rear Wheel Setup | Lug Count | Bolt Pattern | Inch Equivalent |
|---|---|---|---|---|---|
| Silverado 1500 | 1999–2026 | SRW | 6 | 6×139.7 mm | 6×5.5 in |
| Silverado 1500HD | 2001–2006 | SRW | 8 | 8×165.1 mm | 8×6.5 in |
| Silverado 2500 | 1999–2006 | SRW | 8 | 8×165.1 mm | 8×6.5 in |
| Silverado 2500HD | 2001–2010 | SRW | 8 | 8×165.1 mm | 8×6.5 in |
| Silverado 2500HD | 2011–2026 | SRW | 8 | 8×180 mm | 8×7.09 in |
| Silverado 3500 | 1999–2006 | SRW and applicable DRW | 8 | 8×165.1 mm | 8×6.5 in |
| Silverado 3500HD | 2007–2010 | SRW and DRW | 8 | 8×165.1 mm | 8×6.5 in |
| Silverado 3500HD | 2011–2026 | SRW | 8 | 8×180 mm | 8×7.09 in |
| Silverado 3500HD | 2011–2026 | DRW | 8 | 8×210 mm | 8×8.27 in |
SRW means single rear wheel. DRW means dual rear wheel, commonly called a dually.
Historical wheel-fitment documentation lists the Silverado 1500 at 6×139.7 mm, 2001–2010 2500HD at 8×165.1 mm, and 2011-up 2500HD at 8×180 mm. It also identifies the 2011-up Silverado 3500 dually pattern as 8×210 mm.
Current GM Genuine Parts listings confirm that modern Silverado 2500HD and Silverado 3500HD single-rear-wheel wheels use an 8×180 pattern.
The model distinction matters more than the number of lug nuts. Two Silverado wheels can both have eight lugs and still have completely different pitch circle diameters.
What Bolt Pattern Does a Silverado 1500 Use
Every Chevrolet Silverado 1500 generation from 1999 through 2026 uses a 6×139.7 mm six-lug bolt pattern, also written as 6×5.5 inches.
Recommended Best Deal Products
GM’s current OE wheel catalog continues to specify 6×139.7 for 2019–2026 Silverado 1500 applications.
If you need a deeper half-ton-only reference, the Chevy Silverado 1500 bolt pattern chart by year covers that application separately.
A 6×139.7 specification means the wheel has six lug holes positioned around a 139.7 mm diameter circle. The imperial equivalent is 6×5.5 inches.
Silverado 1500 wheel fitment is consistent at the lug pattern, but that does not mean every Silverado 1500 wheel is automatically interchangeable. Wheel diameter, width, offset, center bore, brake clearance, and load capacity can still change.
How Silverado 2500HD Bolt Patterns Changed in 2011
The Silverado 2500HD bolt pattern changed for the 2011 model year, creating one of the most important GM HD wheel-fitment breakpoints.
2001 to 2010 Silverado 2500HD
The 2001–2010 Chevrolet Silverado 2500HD uses:
Recommended Best Deal Products
- 8 lug holes
- 8×165.1 mm bolt pattern
- 8×6.5 inch equivalent
- 116.7 mm center bore in historical fitment references
This is the traditional GM eight-lug pattern used on many older heavy-duty trucks.
2011 to 2026 Silverado 2500HD
Starting with the 2011 model year, the Silverado 2500HD changed to:
- 8 lug holes
- 8×180 mm bolt pattern
- Approximately 8×7.09 inches
- 124.1 mm center bore in established fitment references
Historical technical fitment data records the change from 8×165.1 to 8×180 beginning with the 2011 Silverado 2500HD.
GM’s OE parts catalog also lists 8×180 wheels across current Silverado 2500HD applications, including 2025 and 2026 trucks.
An older eight-lug wheel cannot bolt directly onto a newer 8×180 HD hub simply because both wheels have eight holes. The bolt circle itself is different.
Which Bolt Pattern Fits Silverado 3500HD SRW and Dually
Silverado 3500HD fitment requires one more check than the 2500HD because you must identify whether the truck has single or dual rear wheels.
2007 to 2010 Silverado 3500HD
The 2007–2010 Silverado 3500HD uses the older 8×165.1 mm pattern.
Historical references list a 116.7 mm center bore with this generation.
2011 to 2026 Silverado 3500HD SRW
Single-rear-wheel 2011–2026 Silverado 3500HD pickups use 8×180 mm.
Current GM Genuine Parts listings show 8×180 wheels fitting both Silverado 2500HD and Silverado 3500HD applications.
2011 to 2026 Silverado 3500HD DRW
Dual-rear-wheel Silverado 3500HD trucks use a larger 8×210 mm bolt pattern from 2011 forward.
Dually wheel suppliers identify 2011 and newer Silverado 3500HD DRW trucks with the factory 8×210 pattern.
This difference is critical. A 2011-up 3500HD SRW wheel uses 8×180, while the corresponding DRW truck uses 8×210.
Dually fitment also involves wheel offset, front wheel position, inner rear wheels, outer rear wheels, and hub geometry. Matching 8×210 alone does not guarantee that a dually wheel is correct for every mounting position.
What 6×139.7 and 8×180 Bolt Patterns Mean
A wheel bolt pattern contains two numbers. The first tells you how many lug holes the wheel has, while the second gives the pitch circle diameter, or PCD.
For example:
- 6×139.7 means 6 lug holes on a 139.7 mm circle.
- 8×165.1 means 8 lug holes on a 165.1 mm circle.
- 8×180 means 8 lug holes on a 180 mm circle.
- 8×210 means 8 lug holes on a 210 mm circle.
The common imperial conversions are:
| Metric Pattern | Common Inch Description |
|---|---|
| 6×139.7 mm | 6×5.5 in |
| 8×165.1 mm | 8×6.5 in |
| 8×180 mm | 8×7.09 in |
| 8×210 mm | 8×8.27 in |
Measuring a Six Lug Silverado Wheel
A six-lug pattern is easy to measure because an opposite stud sits directly across the hub.
Measure from the center of one wheel stud to the center of the stud directly opposite it. A Silverado 1500 should measure approximately 139.7 mm or 5.5 inches across the bolt circle.
Measuring an Eight Lug Silverado Wheel
Eight-lug patterns use the same center-to-center approach between opposite studs.
This measurement is especially useful on HD trucks because 8×165.1, 8×180, and 8×210 wheels all have eight holes but are not interchangeable.
What Else Determines Silverado Wheel Fitment
A matching bolt pattern only confirms that the wheel’s lug-hole spacing matches the hub. Several other specifications still determine whether the wheel fits correctly.
Center Bore
The center bore is the opening in the middle of the wheel.
Historical Silverado fitment references list approximately 78.1 mm for Silverado 1500, 116.7 mm for pre-2011 2500HD and 3500HD applications, 124.1 mm for 2011-up 2500HD applications, and 154.2 mm for modern 3500 dually applications.
GM’s current Silverado 1500 accessory wheel catalog lists a hub pilot diameter of about 77.89 mm on an OE 6×139.7 wheel, which aligns closely with the commonly specified 78.1 mm nominal hub size.
Wheel Offset
Offset describes how far the wheel mounting surface sits from the wheel’s centerline.
Two 6×139.7 wheels can have the same bolt pattern while placing the tire in very different positions. Excessive positive or negative offset can create suspension, steering, fender, or tire-clearance issues.
Brake Caliper Clearance
Wheel diameter and spoke shape must provide enough space around the Silverado’s brake calipers and rotors.
This becomes important when installing older OEM takeoffs on a newer truck. A matching PCD does not prove the wheel barrel or spokes will clear the brakes.
Wheel Load Rating
HD truck wheels must support the loads imposed by the truck, passengers, cargo, and trailer tongue or pin weight.
A light-duty aftermarket wheel should not be considered suitable for a 2500HD or 3500HD simply because its bolt pattern matches.
Lug Hardware
Lug thread, lug-nut seat design, and mounting hardware must match the wheel and truck.
For related installation specifications, Truck Guider’s Chevy Silverado 1500 lug nut torque guide covers the half-ton torque application separately.
Will Silverado Wheels Fit Across Different Years
Some Silverado wheels can interchange across generations, but the bolt pattern is only the first compatibility check.
The Silverado 1500 has used 6×139.7 since 1999, giving it far more bolt-pattern continuity than the HD lineup. GM currently continues that same six-lug pattern on 2026 Silverado 1500 OE wheels.
The situation is different with HD trucks. A 2010 Silverado 2500HD uses 8×165.1, while a 2011 Silverado 2500HD uses 8×180.
For a detailed model-year compatibility breakdown, see what year Silverado wheels are interchangeable.
Before treating a wheel as a direct fit, verify:
- Bolt pattern
- Center bore
- Wheel diameter
- Wheel width
- Offset and backspacing
- Brake clearance
- Lug hardware
- Wheel load rating
- SRW or DRW configuration on a 3500HD
Matching all nine checks is much safer than shopping by lug count alone.
How to Confirm Your Silverado Bolt Pattern
Before ordering wheels, identify three basics first: your Silverado model, model year, and rear-wheel configuration.
- Identify the model. Confirm whether the truck is a Silverado 1500, 1500HD, 2500, 2500HD, 3500, or 3500HD.
- Confirm the model year. This is critical for HD trucks because the major pattern change occurred in 2011.
- Check SRW or DRW. A 2011-up 3500HD dually does not use the same pattern as an SRW 3500HD.
- Match the truck to the chart. Confirm the lug count and PCD.
- Check the OEM wheel number. Factory wheels normally have identifying information stamped or cast on the rear surface.
- Verify center bore and offset. These dimensions determine whether the wheel properly sits on the hub and clears surrounding components.
- Confirm load capacity and brake clearance. This matters most on 2500HD and 3500HD applications.
If you are unsure which generation your truck belongs to, the Chevy Silverado generations chart provides the model-year breakdown.
Which Silverado Bolt Pattern Do You Need
The correct Silverado bolt pattern depends mainly on model and year.
For a quick reference:
- Silverado 1500 1999–2026: 6×139.7
- Silverado 1500HD 2001–2006: 8×165.1
- Silverado 2500 1999–2006: 8×165.1
- Silverado 2500HD 2001–2010: 8×165.1
- Silverado 2500HD 2011–2026: 8×180
- Silverado 3500 and 3500HD through 2010: 8×165.1
- Silverado 3500HD SRW 2011–2026: 8×180
- Silverado 3500HD DRW 2011–2026: 8×210
The Silverado wheel bolt pattern chart gets you to the correct lug spacing, but finish the fitment check with center bore, offset, wheel dimensions, brake clearance, and load rating before buying.
5 Common Silverado Bolt Pattern Questions
What Bolt Pattern Does a Chevy Silverado 1500 Have?
The 1999–2026 Chevrolet Silverado 1500 uses 6×139.7 mm, also called 6×5.5 inches. Current GM OE wheel listings still show the same 6×139.7 six-lug pattern on 2026 Silverado 1500 applications.
What Year Did Silverado 2500HD Change to 8×180?
The Chevrolet Silverado 2500HD changed to 8×180 for the 2011 model year. The 2001–2010 Silverado 2500HD uses the older 8×165.1 pattern.
Is 8×165.1 the Same as 8×6.5?
Yes. 8×165.1 mm and 8×6.5 inches describe the same nominal bolt pattern. This pattern is commonly found on pre-2011 Silverado HD trucks.
Does a Silverado 3500HD Dually Use 8×180?
A 2011–2026 Silverado 3500HD dually uses 8×210, not 8×180. The 8×180 pattern applies to the modern single-rear-wheel HD configuration.
Will Any 6×139.7 Wheel Fit a Silverado 1500?
No. Matching 6×139.7 only confirms the bolt-circle dimensions. You must also verify center bore, offset, wheel width and diameter, brake clearance, lug hardware, tire clearance, and load rating before treating a wheel as a direct fit.
