2020 Mustang GT bolt pattern

The

Ford lug pattern

will vary according to model and year, but when it comes to the Mustang, it’s consistent. The bolt pattern for all Ford Mustangs is the same and has been since the first one rolled off the line. That pattern? 5 x 4.5.

What those numbers indicate is that there are five bolts that are arranged in a circle with a 4.5-inch diameter. All bolt patterns are written like this, with the first number being the number of bolts and the second number being the diameter of the imaginary circle they form.

But that’s just the beginning of the measurements you’ll need to know if you want to change out your wheels. You’ll also need to determine your Mustang’s wheel offset, stud size, center bore measurements, and torque specifications.

Factory wheel size: 19”

Stud size: M14 x 1.5 (14 mm diameter, 1.5 mm between the threads)

Offset: 35 to 55 mm

Center bore: 70.5 mm

Wheel tightening torque: 180-220 Nm

The way the stud size diameter is written changes based on whether it’s in metric or imperial units, and thread pitch will either be the number of threads per inch or the distance between the threads.

How to measure your Mustang GT’s bolt pattern

By this point, you should have the specs you need to change out the wheels on your Mustang. But it’s always a good thing to know how to measure a bolt pattern for yourself! Here’s how to do it.

With a ruler or a measuring tape, measure the distance from the outer edge of the lug hole on any given bolt to the center of the bolt that’s opposite from it. Since they’re in kind of a star pattern, none of the bolts will be directly across from each other, so just pick either of the ones that are the closest.

The measurement is your diameter, and that combined with the number of bolts makes up your bolt pattern.
