The Chevy Impala has seen a lot of ups and downs in its decades-long history. Luckily, the 10th and final generation of the classic nameplate saw the Impala leaving the field on an upswing. The 2017 model is beloved for its smooth ride, sleek and classy interior, and powerful V6.

These features are more than enough to keep many drivers happy. But if you’re looking to class up your Chevy’s exterior, you’ve probably considered a wheel upgrade. Before you get started, you’ll need to know your vehicle’s bolt (aka lug) pattern, as well as a few additional specs.

Read on for the 2017 Impala’s bolt pattern, plus instructions for how to measure it yourself at home.

2017 Impala bolt pattern

The 2017 Impala was offered in three trims—the

, and

Premier

. Each features the same 5x4.75 bolt pattern on its wheels. If you’re wondering what a bolt pattern is, you’re not alone. Here’s a more detailed explanation.

All vehicles have a bolt pattern. You may hear it referred to as a lug pattern, but they’re the same thing. Both refer to the pattern of bolts that hold the wheels on your car. That pattern is expressed as:

# of bolts x diameter of the circle they form

So, when we say your Impala features a 5x4.75 lug pattern, what we mean is that each wheel is held on by five bolts, and those bolts form a 4.75-inch-diameter circle.

Now that we’ve got that squared away, you’ll need a bit more information if you’re looking to upgrade your Impala’s rims or wheels. So, we’ve gathered all that information for you too!

Factory wheel size: 18”, 19”, or 20”

How to measure your 2017 Impala’s bolt pattern

We’re more than happy to share these types of specs whenever you need them, but if you want to know how to find a vehicle’s lug pattern on your own, we can tell you how to do that, too.

Finding a vehicle’s bolt pattern is simple—all you need is a ruler or a measuring tape.

Pick any wheel on your vehicle, then choose any bolt on that wheel. Since your Impala has an odd number of lugs, you’ll find your bolt pattern by measuring from the outside edge of the bolt you chose to the center of a bolt across from it. This measurement should equal 4.75 inches. And since you have five bolts on your wheel, you now know you have a 5x4.75 bolt pattern.

Finding the pattern for an even number of bolts is even more simple. Just measure from the center of any one bolt to the center of the bolt directly across from it. Again, that will give you the diameter of your circle, and then you just count the lugs to get the first part of the bolt pattern equation.
