Bolt Pattern Guide for The Ford Bronco

What Is a Wheel Bolt Pattern?

A wheel bolt pattern is the number of bolts holding a wheel onto a car. The wheel size, known as "diameter" and "width," can vary across vehicles, sometimes within one make/model/year range. Therefore, a set of alloy wheels will usually come with an accompanying bolt pattern guide or diagram to help match them up to vehicles.

If you are looking to purchase aftermarket wheels for your car, it is helpful to know the bolt pattern of your Ford Bronco's current wheels. Once you have found the correct bolt pattern for your vehicles, you can begin to shop for alloy wheels that fit your style.

When purchasing aftermarket wheels for any of your vehicles, especially the Bronco, it is essential to remember that there can be a significant change in the vehicles' perceived height and ride quality when changing or adding wheel options. Therefore, be sure to do your research or consult a pro before making decisions on wheel options.

Additionally, if your Ford Bronco is lifted \make sure the bolts for their alloy wheels fit correctly with the new wheel height. Suppose vehicles purchase bolts for vehicles altered vehicles height. In that case, your Bronco could run the risk of the wheels coming loose, causing damage and an increased likelihood of accidents.

Finding Your Car Bolt Pattern

The new Ford Bronco's OEM wheel bolt pattern is 5x108. However, what if you can't locate that? Unfortunately, finding your car's wheel bolt pattern without the internet isn't always easy, but it is possible.

Bolt patterns standards have a two-number system. The first number tells you how many bolt holes are in the wheel, and the second describes the diameter of the circular pattern of holes. For example, a 4-80mm bolt pattern tells you your wheel has four bolt holes equally spaced on an 80mm circle. Some older and many smaller cars have four bolts arranged in a smaller circle and wheel. On heavy-duty pickups and larger trucks, you'll see more lug nuts forming a larger circle.

How to measure the bolt pattern

4-bolt Measure in a straight line from center to center of two bolt holes sitting directly across from each other.

5-bolt Since the bolts aren't directly across from each other; you can get a rough estimate by measuring from the backside of one hole to the center of the third bolt hole. To get an accurate measure, however, requires a special tool.

6-bolt Like a four-bolt pattern, you'll measure from the center of one bolt hole to the center of the bolt hole directly across from it.

8-bolt patterns are measured in the same way as four and six-bolt patterns.

Is the Bolt Pattern Stamped on My Original Equipment Wheels?

Yes, it is, but you may need to take the wheel off to find it on the backside of the wheel (not the side facing you). They may also be on the inside edge of your outside rim.

What the Numbers Mean

If you see markings on the wheel rim, it will show something like this:

9J x 18 H2 5/120 ET47

• 9 is the wheel width
• J is what's called the bead profile
• x means the wheel is made in one piece
• 18 is the wheel diameter in inches
• H2 is the wheel flange
• 5 is the number of bolt holes
• 120 is the diameter of the imaginary circle of bolt holes in millimeters
• ET47 is the wheel offset

Please note that since there isn't a standard on how or the exact location OEMs should display these numbers, you may need to search for them.

Lug-centric vs. Hub-centric Wheels

Hubcentric Wheels

OEM wheels come in many different styles and sizes, but they all have one thing in common - they're hub-centric. Hub-centric wheels are designed for the hub center bore of the wheel to be a perfect match to a specific set or range of cars. These hubs will always fit perfectly onto their respective axle without any adjustment necessary.

Lugcentric Wheels

A wheel is lug-centric if the lugs instead of the hub center the wheel. Aftermarket wheels are designed this way to allow fitment to a broad range of vehicles. However, relying on lug nuts for support can cause a lot of trouble for those who drive on lug-centric wheels.

Aftermarket wheel manufacturers often supply hub-centric rings to fit on your car. These metal or plastic rings will have various inside and outside diameters, with one end fitting over the axle while making contact against it at all times.

Spacers for lug-centric wheels aren't optional, so you should make sure you have them. If not, and you have any vertical or horizontal impact, your lug nuts can shear off.

Bolt Pattern Table

The bolt pattern table describes how many bolts or lug nuts are used to fit a Ford Bronco wheel, and of course, the pitch circle diameter. PCD is (bolt circle diameter). So, for example," 6x5.5″ or "6/5.5", where number "6" describes the number of holes and "5.5" is the pitch circle diameter, Piece of cake!
