background
The 2021 Chevrolet Silverado 1500’s bolt pattern is 6x5.5 or 6 on 5.5. This means each wheel has 6 lugs that form a circle with a diameter of 5.5 inches.
If you have a 2021 Silverado 1500 and need to set it up with winter tires, the best way is to get a second set of wheels. Or, you might just want to get it set up with some special rubber for off-roading. Either way, you’ll need to understand your truck’s bolt pattern so you buy wheels that fit.

2021 Chevrolet Silverado 1500 bolt pattern

Every Chevrolet Silverado 1500 from the 2019 to 2021 model years has a bolt pattern of 6x5.5, also expressed as 6 on 5.5. Here’s how you interpret the two numbers in a lug pattern:
# of bolts x diameter of the circle they form
So if we use the Chevrolet Silverado 1500 as an example, we can see that its wheels each have six lugs forming a circle with a diameter of 5.5 inches.
Knowing your bolt pattern is a good start, but you’ll also want to know your Silverado’s stud size, wheel offset, center bore measurement, and wheel tightening torque specifications. Here’s that set of info for your 2021 Silverado 1500:
  • Factory wheel size: 17” or 18”
  • Stud size: M14 x 1.5 mm
  • Offset: -44 to 40
  • Center bore: 78.1 mm
  • Wheel tightening torque: 190 Nm

How to measure your Chevrolet Silverado 1500’s bolt pattern

You should be able to take that info to a tire shop and get what you need, but if you ever wanted to do your own bolt pattern measurement, here’s how!
Take your measuring tape or ruler and measure from the center of one lug to the center of the one directly across from it. That’s the diameter of your circle (the second number in the lug pattern formula), and your first number is the number of lugs (six)!
If you ever have to measure a bolt pattern for a different vehicle with an odd set of bolts, you’ll simply measure from the outer edge of one bolt to the center of one of the opposite lugs. You can also measure from center to center, then multiply by 1.026 to account for them not being directly across from one another.

How to optimize your Chevy’s insurance coverage

Customizing your Silverado 1500 with some new wheels could increase its value and alter its performance, which in turn will alter your insurance rates. This means your current insurance company might try to sneakily raise your truck’s premium the next time you go to renew.
