We won’t blame you if you’ve never thought about your Silverado’s bolt pattern before. Heck, we won’t even blame you if you don’t know what a bolt pattern is. But if you’re looking to do any upgrades or swaps with your truck’s wheels or rims, you’re going to need to find out both, and fast. That’s why we’ve created this guide.
Read on to find out everything you need to know about your 2013 Chevrolet Silverado’s bolt pattern, plus we’ll throw in the extra specs you'll need to make sure your wheel or rim upgrade is both effective and safe.
2013 Silverado bolt pattern
Trucks like the Chevy Silverado come in a seemingly endless variety of trims and configurations. Luckily, regardless of cab size, bed size, trim, or even wheel size, your 2013 Silverado will feature the same 6x5.5 bolt pattern.
Now, let’s find out what that actually means.
Whatever you drive, your vehicle’s wheels are held on by bolts. You can also call them lugs—the names are interchangeable. These bolts form a pattern that’s expressed as
# of bolts x diameter of the circle they form
Your Silverado’s 6x5.5 lug pattern tells you there are six bolts holding your truck’s wheels on, and those wheels are set into a 5.5-inch-diameter circle. Mechanics, enthusiasts, and auto parts dealers speak this equation as “6 on 5.5,” and now you can too!
Don’t run to the auto parts store just yet, though. You still need a few more specs, and we’ve got the for you right here:
- Factory wheel size: 17” or 18”
- Stud size: 14x1.5 (14 mm stud with 1.5 mm thread spacing)
- Offset: 20 to 40 mm
- Center bore: 78.1 mm
- Wheel tightening torque: 190 Nm or 140 ft-lbs

How to measure your 2013 Chevrolet Silverado’s bolt pattern
Want to do it yourself? Luckily, measuring the bolt pattern on any vehicle is super simple. All you need is a measuring tape—or, better yet, a ruler.
Choose any bolt on any wheel and measure from the center of that bolt to the center of the bolt directly across from it. This gives you the diameter of your circle. Then, just count the number of lugs in the circle, and Bob’s your uncle! On your Silverado you’ll measure out 5.5 inches across the two bolts, and you’ll see 6 bolts in the circle.
But what if you’ve got a wheel with an odd number of lugs? No worries! It’s still easy!
Instead of measuring to the center of the bolt directly across from the one you chose, just measure to the spot in the center of the two bolts directly across from it. This gives you your diameter, then you just count the bolts, and Bob is, once again, your uncle.
