Are you planning to replace your Silverado’s wheels with a set coming from a Hummer and want to know if they will fit? You’ve come to the right place, for we have researched this question and have the answer for you.
The wheels from a 2010 Hummer H3 will fit a 2022 Silverado, a 2022 Silverado LD, and a 2022 Silverado 1500. However, it will not fit a 2022 Silverado 2500 and a 2022 Silverado 3500.
Let’s talk more about why a set of wheels from the Hummer will be a fit for some Silverado models but might not be ideal for use in the succeeding sections. Learn about the different factors to consider when matching wheels from two different vehicles or when buying a new set in the sections below.
What Is A Hummer Wheel’s Bolt Pattern?
The bolt pattern of both trims of the 2010 Hummer H3 (the 3.7i and 5.3i) is 6X139.7. This is the same with the bolt pattern of the 2022 Chevrolet Silverado, the 2022 Chevrolet Silverado LD, and the 2022 Silverado 1500.
However, the 2022 Silverado 2500 and the 2022 Silverado 3500 have a bolt pattern of 8X180. This means that wheels from the Hummer will not fit these two Silverado variants.
Additionally, the center bore should also be taken into consideration.
The center bore of both Hummer trims is 117 millimeters, while the center bore of the 2022 Silverado, 2022 Silverado LD, and 2022 Silverado 1500 is only 78.1. On the other hand, the center bore of the 2022 Silverado 2500 and the 2022 Silverado 3500 is 124.1 millimeters.
Although the smaller center bore on the first three Silverado models above means that the wheel will fit, this is not necessarily a good thing. We’ll talk about this in greater detail in a later section.
Let’s look at these numbers more closely in the next section so that you can understand what they all mean.
How Do I Know My Wheel Bolt Pattern?
A bolt pattern or a lug pattern tells you how many holes a wheel has. These are the holes where you insert the bolt from the vehicle to fasten the wheel.
Primarily, the number of holes in a wheel should match the number of bolts that the vehicle has. If it doesn’t, then the tire won’t fit. You can’t just machine a wheel to add holes to match. This will weaken the wheel.
The number of holes is the first number in the bolt pattern code. Thus, in the case of the 2010 Hummer H3, its wheels have six holes.
However, matching the wheel to a vehicle doesn’t end with the number of holes. The holes in a wheel have a specific distance from each other. Some are closer to each other, while others are farther.
Thus, you will also need to know the diameter of the circle that you get by connecting the centers of the holes. This number can be in inches, although the most common is in millimeters.
The millimeter has smaller parts, making it more accurate than inches. Additionally, a millimeter is more universal than inches.
How To Measure Bolt Patterns?
Wheels have odd or even numbers of holes. Thus, measuring the bolt pattern depends on whether it has an odd number of holes or an even number.
To measure the bolt pattern on a wheel with an even number of holes, measure the distance from the center of one hole to the center of the hole opposite it. When you measure the distance between the two holes, a straight line should go through the center of the two opposite holes and the center of the wheel.
To measure the bolt pattern of a wheel with an odd number of holes, measure the distance from the center of one hole to the back end of one of the two holes opposite the first hole. Since you have an odd number of holes, there will be two opposite holes to any single hole that you pick.
Alternatively, you can use a bolt pattern measuring tool that looks like a caliper. Another tool that measures bolt patterns is the bolt template. This is the second number after the “X.”
Thus, for the wheel of the 2010 Hummer H3, the bolt pattern measurement is 139.7 millimeters.
What Is A Center Bore?
The center bore of the wheel, or the spigot size of the wheel is the opening or hole at the center of the wheel. This hole is where the spigot of the vehicle goes through.
In addition to matching the holes for the bolts, the hole for the spigot should also match. If the spigot of the vehicle is larger than the hole on the wheel, then the wheel will not fit the vehicle.
In the case of the wheel of the 2010 Hummer H3, the center bore is much larger than the spigot of the three Silverados that have the same bolt pattern.
Bigger Is Not Better
The Silverado, Silverado LD, and Silverado 1500 all have smaller center bores than the center bore of the Hummer H3. This means that you will need to install a spigot ring to bridge the difference in size.
Why do you need a spigot ring? The spigot carries the weight of the vehicle. When you install a wheel, the spigot should fit snugly into the center bore. This ensures that the weight of the vehicle transfers to the wheel.
Most people think that the wheel studs carry the weight of the vehicle. This is not the case. The wheel studs and lug nuts only secure the wheel to the vehicle.
If you don’t install a spigot ring, the wheel studs will need to support the weight of the Silverado. However, the wheel studs are not sturdy enough to do this. Thus, without the spigot ring, the wheel studs could fail, and the wheel can fall off the Silverado.
A center bore that matches the spigot is even more important in trucks because of the cargo that they carry.
What Is The Offset Of A Wheel?
The offset is the deviation of the mounting surface from the center of the wheel. The mounting surface is the part of the wheel that is closest to the brakes.
If the mounting surface is closer to the curb, then the offset is positive. However, if the mounting surface is closer to the suspension, then the offset is negative. Another way to look at it is by understanding the centerline of the wheel.
A wheel that is 8 inches wide will have a centerline of 4 inches. If the distance from the mounting surface to the rear edge of the wheel is greater than the distance to the centerline, then the wheel has a positive offset.
Meanwhile, if the distance from the mounting surface to the rear edge of the wheel is less than the distance from the centerline, then the wheel has a negative offset.
When replacing the wheels, there should be as little deviation as possible from the stock offset of the original wheel. A very high positive offset can cause the tires to rub against the fender, while a very high negative offset can cause the tires to rub against the suspension.
Any type of rubbing can cause damage to the components of the vehicle as well as to the tires.
The Hummer H2
The Hummer H2 has wheels with the same bolt pattern from 2002 to 2009. However, the wheels from the Hummer H2 will not fit on any Silverado because its wheels have a bolt pattern of 8X165.1.
The Hummer H1
The wheels from a Hummer H1 from 1992 to 2006 have the same size bolt pattern as the Hummer H2. Thus, its wheels will not be usable on the Silverado.
Other Chevrolet Silverado Models
Chevrolet Silverado models from 1995 to 1999 have a bolt pattern of 5X127. This means that the wheels from a Hummer H1, Hummer H2, Hummer H3, and Hummer H3T will not fit a Silverado from these years.
What Size Rims Does A Hummer H3 Have?
From 2005 to 2010, the Hummer H3 has the same size of rims. It uses a 7.5JX16 ET38, a 7.5JX17 ET38, or an 8JX18 ET38.
How To Read Rim Sizes?
The first set of numbers before the letter is the width of the rim in inches. You measure the bead seat of one end to the opposite bead seat.
A tire bead is the edge of the tire that locks into the rim. Wheels have a small slot where the tire bead will lock once you inflate the tire to the correct tire pressure.
The letter after the first set of numbers is the type of mounting flange that the rim uses. Flanges in wheels are the flared edges that prevent tires from slipping out of the wheel. The beads sit inside the flanges.
The next set of numbers is the diameter of the wheel in inches. The number after “ET” is the offset in millimeters. A positive number represents a positive offset, and a negative number is a negative offset.
The wheels from a Hummer H3 will fit some Silverado models. However, you’d need to install a spigot ring to compensate for the difference in the center bore of the Hummer wheel and the spigot of the Silverado.
