When people talk about wheels and tires, one of the most common terms you may hear is bolt pattern. The bolt pattern tells you how many lug holes a wheel has and how far apart they are. For Ford vehicles, one famous size is the 5×5.5 bolt pattern.
This pattern has been around for many years and is still very popular today. Many trucks, SUVs, and classic Ford models use it. In this article, we will explain what the 5×5.5 bolt pattern means, which Ford vehicles use it, why it matters, and how you can measure it. We will also share facts, figures, and a table to make it easy to understand.
What Does 5×5.5 Bolt Pattern Mean?
A bolt pattern is written in two numbers. The first number tells you how many bolt holes are in the wheel. The second number tells you the diameter of the circle that goes through the center of all the bolt holes.
- In 5×5.5, the number 5 means there are 5 bolt holes.
- The 5.5 means the distance across the circle of those holes is 5.5 inches.
So, a 5×5.5 wheel has five lug holes set on a circle that is 5.5 inches wide. This pattern is also sometimes written as 5×139.7mm because 5.5 inches equals 139.7 millimeters.
Which Ford Vehicles Use the 5×5.5 Bolt Pattern?
The 5×5.5 bolt pattern has a long history with Ford. It has been used on many trucks and SUVs, especially older models.
Here are some Ford vehicles that used or still use the 5×5.5 bolt pattern:

- Ford F-150 (up to 1996 in some trims)

This pattern was very common in full-size Ford trucks for decades. It gave strength, stability, and made it easier for these heavy-duty vehicles to carry big loads.
