All Chevy Truck Bolt Pattern Chart with Name and Model Year

Choosing the right wheels for your Chevy truck is an important decision that requires understanding your vehicle’s unique bolt pattern. From stock wheels to aftermarket upgrades, the bolt pattern is the determining factor in fitment. This guide provides a comprehensive overview of Chevy truck bolt patterns from 1971 to present-day models. Whether you’re shopping for new wheels or troubleshooting a fitment issue, having the correct specification is key.

What is a Bolt Pattern?

A bolt pattern refers to the configuration of bolt holes that hold a vehicle’s wheel hub and rotor in place. It is defined by two numbers – the first indicating the number of bolt holes and the second specifying the diameter of the circle they form in millimeters. For example, a common “5×5” bolt pattern has five bolt holes arranged in a circle with a diameter of five inches (127mm).

Why Bolt Patterns Vary

Bolt patterns differ between vehicle makes and models based on size. Larger trucks with heavier-duty drivetrains often utilize a wider spacing to accommodate heavier wheel loads. Four-wheel drive trucks also tend to have a larger pattern than two-wheel drive variants for increased strength and traction. Year-to-year changes were also common as manufacturers upgraded components. Verifying the specific application is crucial for a proper fit.

How to Find Your Bolt Pattern

Measuring your vehicle’s bolt pattern is simple. First, remove any existing wheel or hubcap to expose the lug nuts. Count the number of lug nut holes, then measure the diameter of the circle they form using a tape measure. Alternatively, the bolt pattern is usually marked on the wheel hub or listed in your owner’s manual. For most Chevy trucks, patterns fall into one of a few common sizes that are detailed later in this guide.

1971-1991 Chevy Blazer (2WD) Bolt Pattern

• 5×5″ (127mm) bolt pattern

The original Chevrolet Blazer SUVs from 1971 through 1991 with rear-wheel drive had a 5×5-inch bolt pattern. This arrangement remained consistent throughout the entire first-generation Blazer run.

1971-1991 Chevy Suburban (2WD) Bolt Pattern

Ensuring Correct Bolt Pattern Fitment

It’s crucial to verify a vehicle’s specific bolt pattern matches any new wheels before installing. Bolts that are too wide or narrow can cause fitment issues, potential damage, or safety concerns. When in doubt, check the owner’s manual, and hub markings, or call your local Chevy dealership. A proper bolt pattern is the foundation for a solid wheel and tire setup.

Frequently Asked Questions

Q: Can a 4×4 truck use a 2WD wheel pattern?
While some part-time 4WD systems allow mixing patterns temporarily, it’s not advisable long-term. The four-wheel drive configuration strengthens surrounding components for off-road use and heavier loads. Stick to the manufacturer’s specified pattern for safety.

Q: Can you use a half-ton pattern on a 3/4-ton truck?

In many cases, no. Heavier-duty three-quarter-ton trucks like the Silverado 2500 are engineered with wider 8-lug bolt patterns and wheels to support increased payloads and towing capacities safely. Using undersized wheels risks component failure.

Q: What size wheel will fit a stock 6×5.5″ pattern?

Common wheel sizes for the 6×5.5″ bolt pattern include 15, 16, 17, and 18 inches in diameter. The wheel width will depend more on the vehicle trim and suspension. Stick within 1-2 inches of the original equipment wheel size for proper fitment and clearance.

Q: Are all Chevy Avalanche wheels interchangeable?

Most Avalanches shared the S-10 platform’s 6×5.5-inch pattern, but HD models used the 8×6.5-inch truck pattern instead. Be sure to check the specific Avalanche year, model, and trim before assuming wheel compatibility between vehicles.

Q: What years had a 5×5″ Chevy truck bolt pattern?

Chevy half-ton trucks and SUVs from 1971-1991 (2WD), and 1988-1998 (2WD) had a 5×5-inch bolt pattern. This includes Blazers, Suburbans, and the C/K1500 pickups during those model years exclusively.

With this comprehensive guide, you have all the facts and figures needed to determine any Chevrolet truck’s bolt pattern based on year, make, model, and drivetrain. Remember to always double-check fitment before installing new wheels to avoid issues.

Choosing Wheels That Fit

One of the most important considerations when picking out new wheels for your Chevy truck is ensuring they have the correct bolt pattern, bore size, and offset to fit properly. Here are some tips:

• Bore size refers to the hub mounting surface diameter wheels must match for proper seating against the wheel bearings. Stick to OE size or within 1/4″ difference.
• Offset is the distance between the wheel’s mounting surface and the centerline of the wheel. Too much negative or positive offset can cause clearance issues with brakes or fenders.
• Wheel widths should not be more than 1-2″ wider than the original wheel to avoid rubbing. Narrower is usually okay.
• The lug nut seat diameter must be large enough to fit over hub mounting flanges. Check specs match your truck’s configuration.
• Lighter wheels may work for a daily driver but make sure they are still rated for your vehicle’s payload capacity if towing or hauling heavily.

Taking wheel fit into consideration along with bolt pattern will help you find an ideal set of wheels to upgrade your truck’s appearance while maintaining reliable handling.

Common Bolt Pattern Conversions

While it’s best to stick with your truck’s native bolt pattern setup, some popular conversion kits allow changing between common Chevy patterns like:

• 5×5″ to 6×5.5″ – Late model C/K1500s and earlier trucks/SUVs can be upgraded.
• 6×5.5″ to 8×6.5″ – Allows using larger truck wheels on lighter models like Avalanches with proper reinforcement.
• 8×6.5″ to 6×5.5″ – Let’s later Silverados use smaller wheels/tires but weaken structure over time.

Quality hub-centric adapters securely mount the new wheel while maintaining proper lug nut torque. Stronger springs and hardware provided prevent vibrations over rough roads. Alignment should still be checked after swapping patterns.

Customizing with Non-Stock Wheels

Many truck enthusiasts enjoy customizing their ride with wheels outside standard OE options. A few things to note when choosing aftermarket wheels:

• Ford and Dodge’s patterns are sometimes close but not directly interchangeable with GM bolts. Be certain patterns match.
• Very small or large diameter wheels may not have sufficient backspacing for brake/fender clearance even if the pattern fits.
• Wheels designed for other vehicle classes like sports cars may not withstand truck payload/towing stresses over time.
• Lift kits or overly large wheel/tire combos can cause steering/suspension issues if not properly tuned.
• Check weight ratings are sufficient, especially on HD-duty trucks used for work.

With the right components and setup, customizable wheels can dramatically improve a truck’s appearance. But pattern compatibility and strength should always come before style.

Bolt Pattern Compatibility Through the Years

While GM tried to standardize patterns over time, some changes were made:

• 1971-1991: 5×5″ was common on lighter 2WD models, while 6×5.5″ identified heavier-duty 4WD configurations.
• 1988-2000: Newer full-size trucks shifted to 8×6.5″, while S-10-based trucks retained 6×5.5″.
• 2000-Present: GM unified most half-ton trucks and SUVs on 6×5.5″ for simplicity. Heavier-duty 3/4-tons use 8×6.5″.
• Special Cases: Avalanches and Canyons used S-10 patterns despite the towing abilities of larger siblings.

Understanding period-specific variations can help track down uncommon older patterns like the 5×5″ and troubleshoot fitment issues between model years.

Troubleshooting Wheel Installation Problems

If new wheels won’t seat properly on the hubs, try this checklist:

• Verify bolt pattern has the correct number of holes in the right-sized circle.
• Check lug holes are centered in the wheels – hub-centric wheels ensure true positioning.
• Inspect lug nut seats – should be flat, fully supporting lug nut contour without gaps.
• Examine the hub mounting surface for nicks or unevenness from old wheels. The surface may need deburring.
• Confirm wheel bore is properly sized for the hub – too small prevents full seating, and too large allows side-to-side play.
• Inspect lug nuts fully thread onto studs without binding – replace or wear threads.
• Recheck offset isn’t causing interference after torquing lugs securely.

Proper planning and inspection eliminate mystery when hitting potential fitment snags.

Restoring Vintage Patterns

For classic Chevy trucks, sourcing wheels in original patterns can be tricky:

• The 5×5″ pattern is quite rare, requiring specialty manufacturers or used NOS wheels.
• 6-lug wheels for older 4WD models are also niche these days.
• Resto shops may be able to reproduce wheels stamped in vintage patterns.
• Used wheels periodically surface on Craigslist or collector car dealerships.
• Consider modern wheels with hub-centric adapters to the older patterns if true reproductions can’t be found.

Patience and ingenuity are key for restoring a retro truck to factory condition where unusual bolt patterns are concerned.

Bolt Pattern Reference Resources

Definitively identifying a Chevy truck’s bolt pattern can sometimes require extra help:

• GM Service Information archives list patterns by VIN.
• Popular online truck forums have make/model/year ballast databases.
• Specialty parts sellers catalog trucks by bolt pattern specs.
• Commercial vehicle history services can provide pattern details.
• Take measurements to wheel/hub manufacturer specifications sites for cross-referencing.
• As a last resort, contact local GM dealership parts departments.

Having reputable secondary sources to confirm patterns eliminates uncertainty and guessing when sourcing wheels long after a vehicle was produced.
