S10 Blazer bolt pattern

The bolt pattern for any Chevy Blazer from 2020 to 2021, including an S10 Blazer, is 6x4.72, or six on 4.72. If you are just learning about bolt patterns, every bolt pattern or lug pattern uses the same basic formula:

# of bolts x diameter of the circle they form

A 6x4.72 lug pattern means your S10 Blazer uses six lugs per wheel, set in a circle 4.72 inches across.

However, you need additional measurements before you switch out those wheels or rims. It’s important to know your Blazer’s stud size, wheel offset, center bore measurement, and torque specifications:

Factory wheel size: 18”, 20”, and 21”

Stud size: M14 x 1.5

Offset: 14 to 50 mm

Center bore: 66.9 mm

Wheel tightening torque: 190 Nm

How to measure your S10 Blazer’s bolt pattern

The information listed above gives you enough details to change out your Blazer's wheels for something new—but if you want to double-check those specs, there's a way to measure the bolt pattern yourself.

First, get a measuring tape or ruler. Next, choose any bolt on your wheel and measure from the outer edge of the lug hole to the center of the opposite bolt. Since the Blazer has six bolts, this makes it easy as long as you measure straight across.

That measurement gives you the diameter. The diameter and the number of bolts give you the bolt pattern!

How to optimize your Chevy’s insurance coverage

Wheel mods are just one option for upgrading your Chevy's factory options and creating your own specifications. And when considering mods, don't forget to upgrade your Blazer's insurance while you're at it.

Why? Modding your Chevy ups its value, which can raise the risk factor that insurance companies consider when they examine your car. However, each insurer uses a different formula to determine your premium, so it's worth taking time to comparison shop for a new
