What are the bolts on a Chevy 6-lug?
Chevy reuses bolt patterns, like many other manufacturers. Therefore, there is a good possibility that two vehicles with six lugs will have the same pattern.
The 5.5-inch bolt pattern and the six-lug pattern is the most common one for Chevrolet cars. Since the late 1960s, Chevy has produced 1500 44 pickup trucks with the 65.5 bolt pattern.
Are 6139 7 and 65.5 the same pattern? This is one of the most frequent queries about the Chevy bolt pattern.
They have the same bolt pattern, yes. One is in the metric system, whilst the other is mainly for the American market. That is the only distinction. They are often in tandem.
How Can the Chevy 6-Lug Bolt Pattern Be Measured
Lug patterns with even numbers are simpler to measure than those with odd numbers. The initial measurement will start from the center of one bolt to the center of the bolt directly across from it.
Next, take a measurement from one lug hole to the lug hole that is directly across from it. The units of measurement are millimeters or inches.
We’ll be able to provide you with information on your car’s bolt pattern, the best car tires for your truck, recommended tire rotation schedule, etc.
A bolt pattern is what? The huge hub bore, or the lug hole has three or more holes that have an even spacing apart.
The most typical number of lug holes is five, albeit occasionally four. The pattern needed to bolt a wheel onto a vehicle is referred to as a bolt pattern.
The places on the wheel known as the lug holes are where the lug nut or lug bolt will fit to firmly bind the wheel to the vehicle.
Even though people frequently ignore the bolt pattern and lug holes on the wheels, they play a crucial role in ensuring that the wheels are snugly and securely fastened to the wheel hub and the car.
The bolt pattern Silverado, which is a circular arrangement of these lug holes, aids in determining which wheels you can and cannot mount on the car.
Remember that only wheels with the same bolt pattern as the OEM (Original Equipment Manufacturer), or “stock” wheel, will fit the vehicle.
Before buying aftermarket wheels (and if you’ve already considered how much are car rims), make sure they will fit the car because bolt patterns are vehicle-specific.
Bolt Pattern Types
In addition to 3-lug and 8-lug bolt designs, there are 4-lug, 5-lug, and 6-lug bolt patterns.
Each of these is for installation on particular kinds of cars. The majority of contemporary automobiles have the 5-lug configuration.
Granted it is simple to alter bolt patterns and change them millimeters to inches, especially whenever you are looking to find out the bolt pattern, it’s important to note that the bolt patterns are often in millimeters.
A 5×120 bolt pattern, for instance, designates 5 holes that are each 120mm in diameter.
Usually, the 4-lug bolt designs are mainly for compact as well as midsize vehicles. As one of the most used bolt patterns, they make it simpler to find aftermarket or customized wheels.
There are five different 4-lug patterns: 498, 4100, 4108, 4110, and 4114.
Mid-size, normal, full-size, and luxury automobiles frequently feature 5-lug bolt designs. Because it is by far the most typical layout, finding aftermarket wheels and lug nuts is simple.
The following 5-lug patterns are available:
- 598, 5100, 5108, 5110, 5112, 5114.3, 5115, 5120, and 5120.
- 7, 5×127, 5×130, 5×135, 5×139.
- 7, 5×150, 5×155, 5×165.1 and 5×205.
For pickups, midsize SUVs, and full-size SUVs feature 6-lug bolt designs. The 6-lug bolt design usually makes it easy to find aftermarket wheels for your vehicle
There are six different 6-lug bolt patterns: 6114.3, 6115, 6120, 6127, 6132, 6135, and 6139.
Midsize, normal, full-size, and luxury automobiles typically feature an 8-lug bolt design. It is much easier to locate custom or aftermarket wheels thanks to the widespread use of the 8-lug bolt designs.
There are four different patterns that make up this bolt pattern: 8165.1, 8170, 8180, and 8200.
Bolt Pattern Measurement Procedure
Bolt patterns use a two-number classification system. The first number represents the number of bolt holes in the wheel, while the second number is the size of the fictitious circle those holes form.
For instance, a 5100 bolt pattern denotes 5 evenly spaced lug holes on a 100mm circle.
The wheel’s center is used to measure the distance. Large cars typically have a wider bolt circle and more bolts.
Fewer bolts will be in a tight circle on smaller automobiles. Below are examples of the most precise methods for measuring bolt patterns.
4 Lug Bolt Pattern
You measure a 4-bolt pattern from center to center of two bolt holes that are exactly across from one another.
5 Lug Bolt Pattern
Given that the bolt holes are not nearby, 5-bolt layouts are frequently more challenging to measure. You can draw a straight line drawn from the center of the third lug hole to the backside of one hole to gauge the measurement.
6 Lug Bolt Pattern
Similar to 4-bolt patterns, you measure 6-bolt patterns by drawing a straight line from the centers of two bolt holes that are immediately across from one another.
8 Lug Bolt Pattern
You can measure 8-bolt patterns in a straight line from the centers of two bolt holes that are next to each other, much like 4-bolt and 6-bolt patterns are.
Dual-Drill Bolt Pattern
Some manufacturers also make wheels with multiple bolt patterns in addition to the above-listed bolt patterns.
You can install the wheel on two different bolt patterns thanks to the extra pair of lug holes on dual-drill bolt patterns.
A wheel with the design 5100/114.3, for instance, has ten total holes. This supports both the 5100 and 5114.3 bolt designs.
Chevy Silverado Lug Pattern
The bolt pattern Silverado 1500 produced between 1999 to the present is 6 x 5.5 inches (6139.7mm).
Furthermore, the center bore of the wheel measures 78.1mm, as well as its six M14 x 1.5 lug nuts, will require 140 lb-ft (190 Nm) of torque for proper tightening.
That, however, hardly captures the entire picture. For every iteration, you get a thorough description of the lug pattern. And make sure that you don’t over-torque (aka over-tighten) those lug nuts. Otherwise, you’ll need to get the stripped lug nut remover tools out.
Specifications For Wheel Fitment By Generation
You need to be aware of more than just the bolt pattern Silverado in order to properly install a wheel on your Silverado 1500.
The details that you will need to know pertaining bolt pattern Silverado 1500 generation is below. These comprise the center bore diameter, wheel tightening torque, the use of lug nuts versus bolts, and bolt thread size.
Of course, there are other engine choices and trim levels available for the Silverado 1500. However, within a generation, these lug specs, bolt patterns, and bolt pattern Silverado do not alter.

Retightening The Bolts
As previously stated, the Silverado 1500 and higher models all feature six lug nuts. Whenever you put back the wheel back into the car, you need to fasten these in an accurate manner.
Chevrolet suggests that you fasten these nuts in the manner depicted below. You must go in a crisscross fashion.
To begin, use a wheel wrench to tighten all of the nuts.
Please be careful to only tighten them halfway; else, issues will arise.
You should tighten them to the specified lbs-ft or Nm in the second round using the wheel wrench.
Take note that the bolt on the most recent model of the Silverado 1500 needs tightening to 140 lb-ft.
Your wheels should also have a center cap or cover. You will need to fasten these using the same design.
Please use your hands to firmly tighten them. Then, you can tighten them a quarter turn using a wheel wrench.
Furthermore, it’s important to ensure that the lug nuts are in place even after 30 miles of driving. Please check to make sure they are all in place and still tightly secured.
If not, tighten them once more and check again. The wheel will need to be changed if this continues.
8 Lug Chevy Bolt Pattern
The 86.5′′ bolt pattern wheels must use the Chevy 8 lug bolt pattern. 8 lugs make up the front of this style, and 6 lugs make up the back.
When did Chevrolet modify the 8-lug bolt pattern?
Yes, in 2011 GM switched to a larger bolt pattern. They also altered the wheels’ offset, inter-axle shafts, and brakes at the same time.
The 8-lug is still used by Dodge, however, GM wheels will not fit a Dodge vehicle, and vice versa. I’m aware that wheel spacers are required in order for them to fit.
The 8-lug GM wheels manufactured up to and including 2010 as well as current-model Dodge rims will fit, albeit the highest available size is 17 inches.
How Many Bolts Are In A Chevy 5 Lug
A Chevy 5 lug wheel has a lug pattern of 54.75′′ (5120.7mm).
These wheels came out between the years 1982 and 1993. The majority of tire stores that sell aftermarket wheels have this very popular wheel type. But what are the advantages of a 5-lug bolt pattern when you compare it to a 4-lug bolt pattern?
First, the 5-lug bolt pattern can handle more weight and is better suited for larger wheels and heavier trucks and vehicles. They are also a good choice for performance cars. in case one lug nut comes off, the remaining 4 will still offer decent support.
However, on the other hand, the 4-lug bolt pattern is a lot easier to manufacture as they don’t have less unsprung weight.
8-Lug Chevy vs Ford Bolt Pattern
The 86.5′′ bolt pattern wheels must use the Chevy 8 lug bolt pattern. 8 lugs make up the front of this style, and 6 lugs make up the back.
This bolt pattern is used by the majority of domestic trucks, but various bolt patterns are currently offered for models of trucks such as the Toyota Tacoma and Nissan Titan.
For trucks and SUVs, the Ford 8 lug bolt pattern is a common choice. This design, which measures 17 by 10 inches, is common on the Ford Bronco, Ford Expedition, and F-150 pickup trucks. A lot of trucks and SUVs employ this design, which is a standard size.
Will 8-lug wheels from Chevy and Ford fit one another?
Given that different car models can have varied wheel diameters, this is a challenging topic to answer. To be sure which wheels will fit on which vehicle, it’s crucial to get in touch with an automotive specialist.
But, can an 865 fit an 8170?
With the purchase of the Set of 4 Hub Centric Wheel Adapters, 8-lug, 165.1mm hub bolt patterns can be changed to accommodate 8170 wheel bolt patterns.
These adapters, which are made of 6061 billet aluminum and have the necessary offset and backspacing to trick the hub into believing the wheel is the vehicle’s original size, are machined to OE specifications.
The adapter set will also help you have enough room for tires and brakes by allowing you to move your wheels outside by 1.5 inches.
8-Lug Chevy 2500 Bolt Pattern
The 8x180mm bolt pattern Silverado on the Chevrolet Silverado 2500HD enables it to be used with wheels that have eight lugs and are spaced 180mm apart.
Additionally, the lug nuts on these vehicles have an M14 x 1.5 thread size and a 124.1mm center bore. These lug nuts require 140 lb-ft (190 Nm) of torque to tighten.
The fourth generation of the Chevrolet Silverado 2500HD was built between 2011 and 2019. Your Chevy 2500 8-lug truck’s body and wheels can both be mounted using this adaptable bolt design.
When Did GM Change The Design Of Their 8-Lug Bolts
The bolt design for GM’s 8-lug wheels has changed. The 7 x 5 bolt pattern Silverado is the latest standard for GM and General Motors trucks.
This modification was implemented in 2011 in order to bring their standard in line with those of certain other OEM businesses.
Before mounting a new tire on a truck built in 2007 or earlier with an 8-lug wheel, you should replace the wheel to prevent your truck from experiencing additional wear and tear.
Are There Standard Chevy 8 Lug Patterns
The spacing that is between the holes all around a wheel is the lug pattern. The quantity of lugs or bolt holes on the wheel determines this spacing.
One of the most popular types, the 8-lug pattern includes eight evenly spaced bolt holes in 5- or 6-hole configurations. The majority of wheels for vintage and classic cars have an eight-lug configuration.
Up until 1996, Chevy trucks had 8-lug wheels, though newer versions had hub-centric wheels instead. Different lug patterns on hub-centered wheels won’t cover hubs since they stick out into the center bore of the wheel.
For instance, vintage 1992–1996 Ford 8-lug wheels will fit over a Ford hub but not a Chevy hub. Surprisingly, you can use them with Chevy trucks labeled as pre-1993 or newer, but not the other way around.
What Is The Chevy 8 Lug Bolt Pattern
Your Chevy truck’s bolt configuration is 8-165. The lug nuts, which have a diameter of 6.5 inches, are the same size as the central hole that you would use to mount a hub.
If you have one of these patterns, there is no danger of getting an improper piece of hardware stuck onto vacuum lines or other important spots on the automobile. A hub made for this standard may differ somewhat in how it fits a different car.
For comparison, do check out our detailed guides on the bolt pattern on the Ford Fusion, as well as the lug pattern on the Ford F150 for more insight on why this matters. And since you’re here, we’ve plenty of other Silverado-related resources that might be of good use to you.
